GDC 2015 recap

March 10th, 2015

GDC 2015 has ended and those who weren’t there have gotten their information solely in 144 character fragments. I wanted to write up a quick post of my experiences at the conference, key takeaways, etc. to give those who weren’t able to there a (slightly) more comprehensive idea of what transpired.

To be clear, there was no drinking, having fun, or gallavanting because we’re all professionals and don’t have time for such shenanigans.

The big takeaway from the week as a whole is that everyone is interested in VR and 3d audio, but we’re still figuring out what to do with it.

I arrived Monday night, not to hit audio bootcamp on Tuesday, but because I’m lucky enough to work for Sony and have the opportunity to be a part of their Game Technology Conference before GDC in which I sit in a room with some of the most talented game audio developers in the world and talk about game audio. We heard talks from Evolution studios, some of the Morpheus team, and others from SCEE and SCEA. Talented folks. Here I am sitting in a room with guys from Naughty Dog, Sony Santa Monica, Bend Studio, Sony Cambridge, London, Evolution, Sony Japan, Insomniac. It’s a very humbling experience being surrounded by such incredible, inspiring talent, all the while having great discussions to further inspire and innovate.

I actually cut out of conference for an hour to catch the beginning of the Audio Bootcamp and Jay Weinland’s talk on Weapon Design in Destiny.  I always enjoy talks where people share some screenshots of their Wwise projects. I find it fascinating how we all use the tool in different ways to sometimes do similar things and other times create totally innovative concepts. The two big “that was cool” moments from Jay’s talk which have been done elsewhere, but were elegantly implemented: the notion of silence duckers: using a Wwise silence plugin with 0.1 second length played with an explosion to duck most other sounds by 12dB for the .1 seconds with a .2 second recovery time to carve out some space for the explosion without being detectable. Also their passby solution for rockets in which they created several sounds of the same length with the pass by the listener at the same spot in each file. Based on velocity of the object they trigger the sound based on when the midpoint should go by the listener and if it’s too late to start the sample from the beginning, they seek into it.

One final comment about Audio Bootcamp: since the beginning it’s been more of an “introduction to game audio” day. This year it seemed far more like an extra day of the audio track. So many interesting speakers and talks on music, technical sound design, VO, etc. Pretty cool that audio has so many compelling topics that it takes more than the 3 day conference to cover all pertinent info.

Wednesday started with a talk from Jim Fowler of Sony talking about using Orchestral colors in Interactive music. While it was a bit esoteric for non-music people, Jim did a fantastic job of presenting a great concept in regards to working with music stems: rather than arrange music by instrument or section, arrange it by function within the score. He then showed how he marks up charts for an orchestra so they can tell what they need to play when. Really neat concept, and some lovely dry, British humor to boot.

I then headed over to my one non-Audio talk by Alistair Hope from Creative Assembly on building fear in Alien Isolation. Unfortunately it was only a half hour talk, but somehow he managed to get through all of his content. The key takeaways here were how they used prototyping to figure out their concept and then stayed true to the concept through further testing. These guys really get the meaning of the term “grounded” in regards to design and how something is grounded when it makes sense in the world you are building, rather than the real world. Interestingly they toyed with making it a 3rd person game at one point due to the fact that most other survival horror games have been 3rd person and there was also the conflict at the time with FPS Aliens Colonial Marines. In the end they found that 3rd person felt like an Alien game, while 1st person felt like Alien, so they stuck to their guns. The last, most important thing, which should apply to all projects were their Key Universal Learnings. The seem so self-explanatory, but are definitely worth reminding ourselves (and our teams) of when working on a project:

  • Have a Strong Vision
  • Everything should work together to support that vision
  • Deliver strongly on the vision
  • Believe in what your doing

Next up for me was a talk from Harmonix on creating the interactive musical experience of Fantasia. My one wish for this talk was that they brought a Kinect along because it was cool to see some movies of their prototypes in Max/MSP and Live, but watching the movies of gameplay made we want to see how the 3d motion of the user caused various changes in the music. Still it seems like everyone that works at Harmonix is a musical tech wizard and they definitely have a lot of fun developing their gameplay.

Wednesday concluded with a talk from Monolith about Shadows of Mordor which was really great. Brian Pimantuan, the audio director as well as his programmer and staff composer did a really good job of showing how they set out to maximize emotional resonance in the open world environment of the game.  Some of the interesting things they did were moving the listener back to the player to make things more intimate and tie things closer to the player. Similar to Condemned, they added music stingers to impacts on Uruk Captains. Really nice, subtle touch of integrating music into sound design and increasing intensity. Also really dug they way they took a few queues for the Nemesis Orcs and made each one unique and reinforced each Orcs character by chanting the Orc Chieftains name over the music cue. Really slick. Also of note, though they barely touched on it, was how great the mix of this game is. So much going on and just a fantastic job of keeping everything balanced and sounding good.

Thursday was the (almost painfully) long day. The morning began with Oculus’ Brian Hook and Tom Smurdon talking about their experiences thus far with audio and virtual reality. They had some interesting perspectives on how we need to handle audio for VR including all mono sounds and a very judicious use of music. Gone are the days of simple tagging of anim roots with sounds to be replaced with a joint-based animation tagging system since the immediacy of virtual reality means we need greater spatialization of near-field sounds. They provided a great, early insight to playing with audio in VR games. It also made me very excited and encouraged about the work Sony is doing on the same front. The Oculus programmer, Brian Hook, made a VST plugin of their 3d audio SDK implementation which allows Tom, the audio lead, to easily audition 3d audio sounds before getting them in the game. A nice touch and one we should (hopefully) expect to see for other 3d audio solutions soon.

I had plans to troll the expo floor for a bit after the Oculus talk. I tried to see Nuendo’s implementation into Wwise 2015.1, but the line was too long, so I started to wander and ran into Mike Niederquell of Sony Santa Monica and Rob Krekel from Naughty Dog. We spent the next hour chatting about a gamut of topics including best practice uses for the PS4 speaker controller (perhaps a future blog post). Before I knew it, it was time for the next talk, which was Joanna Orland of SCEE talking about how to get a team on board and understanding your audio vision. Using the Book of Spells project she introduced the concept of creating a common language with the rest of the team so they could provide feedback to audio without being obtuse. In the Book of Spells example, each spell type was given an elemental name derived from natural sounds. If the rest of the team wanted changes to a specific sound they would use these elemental descriptions to help describe to Joanna the exact aesthetic they were looking for.

Rob Bridgett gave a very compelling talk on adaptive loudness and dynamics in mobile games next. His talk was arguably about much more than mobile games and easily spills into handhelds and also has implications for consoles. Rob is doing some supercool stuff out at Clockwork Fox. Not only does he do different mixes and loudness settings via compression based on whether the user has headphones connected or not, he also uses the device microphone to measure the noise floor of the room to help determine optimal loudness for the game mix. Brilliant adaptive techniques which, given the availability of a microphone, should be used in consoles as well.

Next up, Martin Foxton presented a talk on modular sound design using the Frostbite engine. His concept was essentially the notion of building sound events or in-game sound effects from smaller building blocks of sounds which can be reused as necessary and also creating templates for these sounds a la prefabs in Unity where you can create a script to carry over various settings for a sound. If you’re not already using modular sound design, it’s a great way to achieve variety while still maintaining sane bank sizes. It’s the reason every time you fire an R2 smoke bolt in inFAMOUS Second Son there’s 1024 possible derivations of the sound that can play!

The final talk of Thursday was a mind blowing presentation by Zak Belica of Epic and Seth Horowitz of Neuropop, a neuroscience research company. Seth was pretty damn hilarious and I only wish they had another hour or two to discuss their concepts. The takeaway here was that sound was one of the fastest of your six senses (yes, there are six. Seeing dead people is not one of them, but balance is). Anyway, because audio is such a fast sense, especially compared to vision, it means there are fewer possible illusions we can play on the auditory sense. However there are some neat tricks: For example the sound of bacon frying makes most non-vegetarians salivate, especially when you show an image of bacon with the sound. Speed the sound up and show a picture of bees, and people think they’re hearing bees and feel a little more uncomfortable. They showed us a few other really neat tricks including modulating a sound at 18.1 – 22kHz to make the eyeball vibrate and create a discomforting feeling. Using infrasonic distortion panned alternatively left and right to create unease. And even why fingernails scratching on a blackboard used to give everyone such shivers when blackboards existed (the envelope of the sound is identical to a child screaming in pain). Seriously, we all need to do more research into neuroscience and how it affects or manipulates audio perception. There’s a lot we can play with there.

By Friday, brains and livers were full, but there were still a couple more good talks to attend. Before these final sessions, I walked the expo floor and was finally able to check out Nuendo’s implementation into Wwise. It’s not fully realized yet (you can only import audio files, not folders which you can templatize into containers), but it’s a great start which I hope other DAWs will follow suit with. Needless to say, I’m starting to evaluate Nuendo now and hope they come to their senses, realize the opportunity they’re creating for themselves, and offer competitive crossgrades. There’s some great forthcoming features in Wwise 2015 besides Nuendo as well: calling events from other events, batch rename tool, profiler enhancements, optimizations, incremental bank building, advanced cache streaming and more.  Can’t wait to start playing with it!

The afternoon started with David Collins and Mike Niederquell having an informal discussion about the sound design of Hohokum. Super awesome that they did a live demo during their talk. Not only are there not enough live demos at GDC, but watching Mike play through some of the levels made me really want to play the game again. It was cool to watch such a fun, light informal talk and also bask in the joy that is Hohokum. Seriously, if you haven’t experienced it (I would say “play,” but it’s less of a game and more of a audiovisual experience) you should definitely seek it out and give it a go!

A perfect cap on GDC was Dwight Okahara and Herschell Bailey from Insomniac giving a glimpse into the open world sound design of Sunset Overdrive. Key takeaways here were that the audio team helped drive and sculpt the irreverent style of the game by implementing offbeat audio into early “gritty” concepts which brought the rest of the team around to the more fun style we now know and love as Sunset City. They showed off some of their fun tech like contextual storefront dialogue and the horde crowd/walla system and it was fun and refreshing to see such a talented team facing the same frustrations my own team does with streaming, lack of programming resources and other annoyances that plague our daily audiocentric lives.

So that was the talks that I made it to. Granted for every audio talk I went to, there was another at the same time. I missed tons of great talks from Matthew Marteinsson of Klei talking about Early Access to  the PopCap team blowing minds with their work with Wwise and 5mb of memory to create Peggle Blast on iOS to Jon Moldover, Brian Schmidt and others talking about turning music games into instruments and more of an interactive experience.

One final note which I’ve said so many times this past week and hope to never stop repeating: the game audio community is something truly special and wonderful. Hanging out with and meeting so many inspiring men and women and being able to openly share our passion is such a fortunate thing. Of all the people I met, hung out with, joked with, talked shop with, etc., there wasn’t an ounce of ego anywhere. Everyone in the community seems dedicated to each other and hellbent on push our entire industry forward together and I can’t express how lucky I feel to be just a small part of that experience.

The Sound Design of inFamous Second Son: Neon Power

October 23rd, 2014

In contrast to past inFAMOUS games, Second Son was a tricky beast in that our power sets were pretty abstract. Electricity can really hurt someone, but smoke, neon, and video? This was definitely one of the many challenges we faced with the sound design of the powers. For neon, we took a pretty direct approach and then got creative with our source materials.

We struggled early on with making neon sound “neon” and not “laser.” There was some confusion during development in which power we were making as those two words were often interchangeable. (Fetch even refers to herself at one point in the game as “Laser Girl”). Making her sounds laser-y was ok, but at the same time I didn’t want to tread on the hallowed ground of Ben Burtt. I actually cursed his name a few times during production because Andy had made some beautiful sounds that unfortunately sounded too Star-Wars-laser-gun. Andy  had a REALLY long spring (originally an induction coil for an industrial kiln we got from a local glass maker named Chris Daly) attached to the ceiling of his office. Whenever he would accidentally hit it, I would hear the telltale “pew pew” in my office next door.

The first element we captured which really felt “neon” was an actual neon tube. We have a couple Sly Cooper neon signs in the office, so I took my Barcus Berry contact mic and attached it to one and got some really nice neon hum. For more variety we captured a bunch of fluorescent lights as well, both via contact mics and using a Sennheiser MKH 8060 to capture various flickering sounds of turning them on and off. I have a very old fluorescent fixture in my house that created some amazing sounds which we ended up using for neon power sources powering down. And Delsin’s neon drain was composed of several tracks of neon hum processed through Izotope Iris with various frequencies cutout and some filter sweeps.

For the rest of Delsin’s powers, Andy got REALLY creative. As you’ll see in the video below no sounds were off limits and we used a broad range of varied sounds to create the final neon palette. Andy used Zynaptiq’s Morph plugin extensively to do some interesting blends of EMF interference and various hits on the aforementioned induction coil. Other tricks up our sleeve included an old signal generator I have which emits square and sine wave sweeps and some very cool power on and off sounds and a crazy electric shocking device from the 50s which would shoot small arcs of electricity at anything you put near it.

Once we got our power set close to completion, it was time for another milestone meeting and thus time for another movie to show off our work. The response from the team from our previous movie, the smoke “Sonic Equation,” was so overwhelmingly positive, I felt compelled to do another. Sure the equation doesn’t EXACTLY equate to the sounds as they are in the game, but it at least shows off part of our design methodology as well as the fun we’re still having.

Next time, we’ll discuss the enemy concrete powers and show some of the abuse we wrought upon varied chunks of concrete!

The Sound Design of inFamous Second Son: Smoke Power

October 7th, 2014

You know how sometimes you have lofty plans to do a project and then months later you think, “What the hell happened? I still haven’t gotten to that thing I meant to do months ago!” Well that’s pretty much where I’m at. I’ve been meaning to write a few short posts about some of the sound design we did on inFAMOUS Second Son for quite some time, and I’m FINALLY getting around to it. I hope this to be the first in a series of posts with an entertaining movie or two showing off some of the sounds we captured to make our various sfx in Second Son and how those ended up sounding in-game. Since the powers are the biggest sonic show piece of the game, I figured we’d start there.

A lot has already been written about smoke power, but since it’s the first power you gain in the game, I’ll touch briefly on it one more time in part just to show you the movie below.

But before that here’s something which may be of interest that has never been seen or heard outside of Sucker Punch.  The first thing we ever did in regards to powers on Second Son was to concept some ideas of what these powers may sound like. We had NO idea what they were going to look like (and as you can see from the video we were even concepting powers that never made the cut into the game). This was merely an exercise to start playing with sound and seeing what kinds of things were resonating with us in regards to these potential power sets. A lot of what we started with helped inform our extensive recording sessions to capture elements to mold and bend to our will. Other concepts we tried here didn’t work and were abandoned. For example, I thought it would be cool if the player’s footsteps had a sweetener applied to them based on your current power set. In the end it felt too heavy handed so we cut it. We played around with the notion of USTV feeds making their way into the video powers sounds (similar to Andy’s Neil Armstrong clip in the concept for what was then called TV powers), but that also just didn’t work in any meaningful way. None of the sounds you hear in this concept made it into the game, but it at least gave Andy, our senior sound designer, and myself a jumping off point to explore from.

Smoke was the first power we worked on, but it was also one of the most challenging: how do you make something as amorphous as smoke sound powerful? Furthermore, how do you make it sound like smoke, and by that I mean NOT like fire. These were the challenges before us. I noticed some steam pouring out from a grate in the ground one day and thought that could be interesting. But it made no sound! We experimented with other air releases from helium tanks and compressed air, but none of it fit the bill. I pretty quickly gravitated towards charcoal. I don’t mean those neatly-formed imitation charcoal briquettes either. I’m talking real burned chunks of wood. I knew from ample barbecuing experience that they made really interesting crackling sounds when burned and also they had a resonance to them when moving around which was kinda unique. After buying a couple bags of charcoal and a small grill I set to work doing most imaginable things to these chunks of burnt wood: moving them around, bouncing them off each other, crushing them, burning them, lighting them on fire and then dousing them, etc. It was a great start. Many other elements ended up playing into the final sounds: surprisingly blowing air through a plastic tube became a very important element in Delsin’s smoke dash and various movements of sand also played a role in both quicker smoke attacks and Delsin’s navigation abilities. Below is a video showing off some of these elements as they were recorded and as they sounded in the game. One quick word on this video: it was originally shown as part of a company meeting. Every milestone during production, each team would show a short video highlighting their work over the past several weeks. We liked to show the team not only how much fun sound design is, but how much fun we have doing it.  Enjoy and stay tuned next week for an exposé on Neon powers!

The Evolution of a Feature: Diegetic Music in Infamous Second Son

March 23rd, 2014

While I’m proud of so much of the audio design in inFamous Second Son, one feature stands out as a testament to never letting go of a good idea. It was a concept, not new or necessarily innovative, that began incubating around 7 years ago. It wasn’t until 2013 that I was able to make the idea work in a title. I thought it’d be fun to trace that feature from its nascent stages through to its full fledged life. To do so, we have to go all the way back in time to a year we called 2007. Ah 2007! There was a palpable hum in the air. The iPhone was introduced by a little upstart company called Apple, Microsoft excitedly released their newest blockbuster (*cough*) Operating System, Vista, and the Nintendo Wii had captured people’s hearts, minds, wrists, and pocketbooks.

I was working at Shaba Games, where we had just finished up the DLC/Gold Edition of Marvel Ultimate Alliance and were looking for a new project. Like many others, we were captivated by the Wii and began working on a concept for a downhill skateboarding game for the platform. Shaba’s other sound designer, Lorien Ferris, and myself began brainstorming ways we could introduce interesting audio to what would ostensibly be a multiplayer racing game. Obviously the skateboard sounds would reign supreme and we came up with an idea of emitters tied to occluder objects such as buildings which would play a quick whoosh as you passed them (an idea I would later harvest for the mobile title, SummitX Snowboarding). Another idea we had was to have music emanating from buildings as you skated by. You’d be going fast and could never go back uphill, so they could be short loops, and once we applied some doppler it would sound awesome!

Unfortunately, while the Wii as a piece of hardware was popular for a slew of years, the software didn’t seem to sell as well, so the project was scrapped before we got very far. BUT after multiple other false starts we were finally given something wholly different and rather exciting: Spider-Man, and what would eventually become Web of Shadows. The goal was straightforward: create a new, unique open world Spider-Man game using the engine from the recently released Spider-man 3. Once again Lorien and I dove into brainstorming cool new features we could implement on the audio front to push the superhero qualities of Spider-man and the real life interactivity of the city. Early on, our storefront music concept was revived. I even added some various loops to embed into some stores simulating dance and jazz clubs and restaurants. Unfortunately we ran into some design problems early on: the storefronts we had in the game didn’t really match the music, they were destructible but we didn’t have a signal to turn off the music when the store was destroyed, and truthfully it just didn’t sound super-convincing to have the sound of filtered talking and clinking dishes and glasses of a restaurant while you’re right outside fighting. You think there’d be screams and hushed whispers. Basically with a tight schedule and a skeleton crew, our storefront music plans would have to wait for another day…

…which came just a year and a half later. We were working on a new superhero title and, with so much of the infrastructure in place now, we spent some time focusing on how to make storefronts believable. We created a multi-stage approach: idle, which would be the default and would play a basic ambient loop. For example some cheesy Italian music emanating from a restaurant. If a fight broke out in the vicinity we would enter a threatened state which would trigger an appropriate one-shot sound effect of screams and maybe instruments falling, dishes breaking, etc. and the music would cease. During high-tension moments (using the same tension meter as our interactive music system) the stores would be silent. Once tension went back down to low, we would slowly ramp up the idle state again until another fight broke out. Perfect plan! Unfortunately the studio ended up shifting gears and we moved from superhero games to music games. The storefront music would lay dormant again…

Fast forward to early 2012. I had just joined Sucker Punch and we were in pre-production on inFamous Second Son. Being back in an open world title, I pretty quickly started to think about my beloved storefront music concept again. Everyone I pitched it to from our creative director to our music team down at Sony HQ loved the concept. So now it was time to design it. The first step was just to get looping sounds emitting from a point in space and figuring out proper attenuation and processing for them. Next it was time to get into the real nitty gritty. I had several challenges to tackle:

A world inside a world

inFamous Second Son takes place in present-day/slightly-future Seattle. It’s not real Seattle, it’s our take on the city, but we still wanted it to be a unique, diverse, funky place, just like real Seattle. We did not want it to be full of grunge music (and that is a story for another day!). I began talking with the environment team to get a sense of the variety of storefronts we would have, and some of what they created helped influence my ideas. Early on, we got an Irish Pub in the game. At which point I thought, man that’d be cool to have it play Irish music during the day and then become a punk club at night. Just like in real life! Then I started to take it further: what if we had traditional Irish music in the earlier times of day, changing to more upbeat, raucous Irish music in the evening and THEN a punk club at night. I was on to something. As we fleshed out the stores my list of music grew and grew. I wanted jazz and Chinese and J-Pop, club, top 40, and why not mariachi music in the Mexican restaurant and thai music, new age music for the yoga studio, and hell even Russian music to put into apartments where the Akulan gangs live? Sure they’re musical stereotypes, but they’re serving the purpose of a low ambient bed, they were never meant to be featured sounds. The result will be filling the city with greater perceived life. I also wanted to reach out to some local bands and get them featured in the game as well. I wanted a lot. So how the hell were we gonna get all this music?

APM to the rescue!

As anyone who’s worked with Sony can attest to, they have some of the most amazingly talented, brilliant people working in their music department. We were very fortunate to have a few of them working closely with us throughout the project. Beyond the game score, we started discussing this source music idea and they carved out some of their budget for a blanket license from APM for stock music. Matt Levine worked directly with APM who would put together playlists for various genres of music we were interested in. He would then send me the lists, which I would review, make notes and approve or ask for more. In the end, we had over 100 tracks in the game spread out over 8 times of day. On the local band side, having been in a band and played with some acts up here I reached out to some friends’ bands and also KEXP, the local college station, and got a list of some potential candidates, several of which made it into the final game. We also started talking to Sir Mix-A-Lot and he really wanted to get some tracks in, too. Now that we had music, we just had to get it playing in game.

Rock Against the Man

As I mentioned, I had earlier rigged up a test playing source music in a test world pretty quickly to help figure out volume, attenuation, and processing. From there, it was on to the challenging part: figuring out how to make it gel in-game. In inFamous Second Son, you play as Delsin Rowe, a rebelistic youth with super powers battling against an evil authoritarian police force, the D.U.P. (Department of Unified Protection, think of the TSA with guns, armor and superpowers). Delsin can clear the DUP out of each district of Seattle as part of the systemic, non-mission open world gameplay. The main theme here is freedom vs. security. The DUP keeps people secure, but Delsin gives them the freedom to do as they wish. To help reinforce this thematically we decided that when the DUP controls a district we’d only hear DUP music. We started with stoic, patriotic sounding cues, but steered the direction more towards syrupy, happy music that provides a wonderfully stark juxtaposition to the menace of the DUP. Once Delsin begins to drive the DUP out of a district, we stop the DUP music from playing in that area and instead let the storefronts come to life with their own individuality. We had a programmer working on the district status rigging, so I asked him to give me a callback signal for when the district status changed. I was then able to use this to determine what district the player was in and whether DUP music should be playing there (it emits from DUP speakers and closed off DUP storefronts), or whether the other storefronts should be allowed to rock in the slowly-becoming-free world. I didn’t feel my initial idea from way back about multiple states work work in this instance. The music acted more as personality for the district than simulating people inside, so I didn’t pursue any kind of multi-state reactive environment. Maybe next time!

At the same time, I wanted some semblance of reactivity and also wanted to ensure the source music didn’t clash with the game score. So I tied the volume of the source music to our tension rtpc (Real-time Parameter Control in Wwise) which is also used for controlling the music intensity. When the player got caught up in combat, the music would fade out, when the combat abated, the source music would slowly ramp back up in volume. As if the owners of the shops were peeking through their windows, and once they saw the DUP dispatched, they cranked up the tunes again. So everything was working great, but now I had dozens and dozens of songs across ten or so genres, how was I going to make it all fit in a shippable state?

Making it fit

Beyond the goal and using source music to bring more life to our fictitious Seattle, I also wanted breadth and variation within the music so you wouldn’t hear the same cue EVERY time you passed a storefront. With a blanket license from APM plus around 20 local musician tracks the content was near limitless. Our soundbank budget, unfortunately, was not. However, every time we change the time of day in the game, we do a load to bring in our new skybox and other time-specific content. In fact, I was already loading all of my ambient sounds with these time of day loads. I devised a scheme to load certain music which could play at any time of day in our core ambient bank, which is always loaded. This ended up being the DUP music and our local acts. For the rest of the store fronts, I would load in 3-5 cues per TOD per genre. This way we have some variation during each time of day, as well as completely new tracks for most storefronts for each time of day change. For the local music, we had all 20 tracks in a random playlist emanating from Sonic Boom Records (a real Seattle record store), Sir Mix-A-Lot played from some of our neon-drainable low-rider hatchbacks (we HAD to have My Hooptie for that!), and the aforementioned Irish punk club featured 3 bands each rotating through a set of 5 songs each. You could theoretically stand by the Irish pub at night and enjoy a whole night of music (if it wasn’t so much fun to run around and use your powers instead!)

My budget for the TOD banks was 7mb, of which I used 2-3mb for source music at VERY low bitrates. We processed them heavily with severe low pass filters and reverb, so we really didn’t need a lot of high end, and the lower encoded bitrates (24kbps OGG) aided in making the tracks sound like they were coming out of crappy speakers inside the storefronts. Most of the cues were edited to around 60-90 seconds since most people wouldn’t really be standing around listening to the music, and we wanted more quantity of tracks than longer songs for this reason.

Here’s a video showing off just a few of the myriad storefronts we added music to. If you have a copy of Second Son, I highly suggest pushing the DUP out of some districts and running around to see how the source music aids in filling in the world without stepping on the score or any critical gameplay. It’s a subtle effect no one would likely notice, but subtlety is often the key to effective sound design.

Adventures in Foley: The Tumbling Machine

November 26th, 2013

A few months ago we were recording some sounds for inFamous Second Son, when I realized how challenging it is to get continuous debris recordings in a tiny recording booth. Inspired in part by the ArenaNet team’s field recording journal from Guild Wars 2, I started to think about a way to be able to record long continuous debris recordings and, lo, the Tumbling Machine was born. I call it the Tumbling Machine because that sounds impressive, but really it’s ridiculously simple, yet pretty damn effective.

I started with a giant plastic garbage can. The issue there is that the molded handles on each side prevent an even roll, so I cut them off with a dremel tool. Now it rolled nice and smooth but the plastic surface would obviously color the sound of the debris. To counteract the resonance of the plastic, I bought a package of eggcrate foam that you put on top of a mattress and lined the bottom and sides of the trash can with it. I tried a few different methods to affix it, but found the most effective was gaffer tape (duct tape would work fine too). The foam did a great job of insulating the impacts so you get the debris, with very little coloration from the plastic. The drawback, is that the foam can trap smaller particles of concrete, wood, glass or other debris you may want to record, but worse off, you could always replace the insulation each time you record a different surface. Here’s a short movie detailing the construction and use of the Tumbling Machine. In this instance, we were using it to record concrete rubble sounds.

It’s a cheap, effective way to make clean, continuous debris movement sounds. Here’s a capture from the concrete recording session cleaned up, so you can hear the results:


The one issue we’ve had is that the debris spills out as you roll the trash can. I’m planning on cutting a fairly wide hole in the lid of the can (so a blimp can fit inside without hitting the edges during tumbling), and cover the inside of the lid with foam to prevent coloration and try to keep the debris inside. Hope this inspires someone to make their own Tumbling Machine or maybe even something more outlandish/useful. Happy Tumbling!
