Unreal Engine Game Audio Tutorial Asbjoern Andersen


Curious what you can do in terms of sound with Unreal Engine's built-in audio capabilities? In this video, Tzvi Sherman demonstrates the many opportunities offered using Unreal Engine's blueprints. And as a bonus, we've also included Tzvi Sherman's video that highlights what a game audio middleware solution such as Wwise brings to the table when using Unity.

Video introduction:

Even without middleware, Unreal Engine’s blueprint system provides the tools necessary for complex audio gymnastics. In this video, Tzvi Sherman demonstrates procedural, spatial, and dynamic sound design. From core basics like adding ambience to a scene through asynchronous looping 2D layers as well as randomized and modulated one-shots to more advanced techniques like controlling audio playback through Blueprints – the sky is truly the limit. If you’d like to follow along or give this a shot yourself, Tzvi uses Epic’s free Action RPG game asset available in the Unreal Marketplace.

Bonus: Learn what you can do with a middleware solution such as Wwise

Adding a middleware solution to your game audio implementation gives you additional possibilities – and below, Tzvi Sherman shows you some of the things you’ll be capable of when using Wwise:
What’s in the video:

For this example of what’s possible in Wwise, Unity’s 3DGameKit asset package is used to show some of Wwise’s integration scripts, like AkAmbient and AkRoomPortals, as well as functions you can use within Wwise itself without needing to touch code. Covering basics like Random, Blend, and Sequence Containers as well as game parameters like Switches, States, and Real-Time Parameter Controls (RTPCs), this video shows an overview of how, as the sound designer, you can take control of implementation and further your creative realization by creating an immersive, in-game world through Attenuation Sharesets and complex 3D Positioning.

  • Presenting the most malfunctioning, dirty old gritty sounding engine failure library out there

    Featuring a staggering 81 files with numerous takes in most tracks, the Kaput sound effects library will cover the bases of almost any broken false starting engine scene one can imagine.

    I can honestly say, that finding the vehicles and tools for this library, has been among the most challenging I have come by. Old and broken cars and trucks are hard to come by these days. Most cars are obviously either driving and dont have start problems, and many of the rest just wont start at all.

    Just as rare are broken petrol powered tools, which usually fit the latter category of not working at all.

    Still, with amazing recording help from recordist Michal Fojcik Soundmind Poland, and just as amazing help from recordist Erik Watland from Norway, the Kaput sound effects library is featuring no less then

    24 different cars, trucks, moped and motorcycles

    1 boat engine

    A few weird sounding power generators and water pump motors

    Back firing exhausts

    Petrol powered garden tools, chain saws, and hedge trimmers

    Brutal construction machines

    From old eastern european trucks, vintage US V8 muscle trucks, classic scandinavian cars, and more modern diesel and petrol engines to funny sputtering dying petrol power tools.

    There is even a few more recording sessions planned, that just didn’t make the deadline for the first batch of sounds in this library (buying a copy of this first of sounds, will of course make any future sounds added to the library free of charge).

    KAPUT is 81 stereo and mono files, 96/24. 1,6 gb big, all UCS ready!

  • Hear the majesty of tropical seas from soothing surf, trickling water laps, and crashing wave sound effects.

  • ACOUSTIC GUITAR FOLEY FOR YOUR PROJECTS
    The SB111 ACOUSTIC GUITAR FOLEY Sound Effects Library is a collection of handling movements, grabs and sets, string noise, drags, impacts, strumming, fingerpicking, tuning, and the smashing and destroying of an acoustic guitar.

    A UNIQUE ACOUSTIC GUITAR FOLEY LIBRARY
    We’ve gone above and beyond just capturing the sounds of strumming and picking – we’ve recorded the nuances and details that make acoustic guitars so special. Like the subtle sounds of the guitar strap as it settles against your shoulder, string noise of fingers on the fretboard, the satisfying sound of the guitar being tuned, grabs and set downs, strings being clipped and even a full restringing sequence. Of course we’ve also included the playing of chords and riffs while strumming and fingerpicking – some played in tune and some out of tune. We did not forget to record your pick as it rattles around in the abyss of the guitar’s sound hole – and the satisfying sound of the guitar being smashed and destroyed. All the details you need to bring realism to your project.

  • Car Sound Effects Broken Car Engine Play Track 5 sounds included, 28 mins total $27

    My car engine broke! As a result of making a huge costly mistake caused by accidentally skipping an oil change service from getting dates and miles mixed up (on top of being a higher milage car), my 2006 Volvo V50 T5’s engine starting making incredibly loud knocking, clicking and rattling sounds. Took it for one last drive before it was picked up by a junk yard, and recorded the process. I put a DPA 4061 and a Rode NT5 in the engine and drove it around the neighborhood, first on residential streets, then drove it harder on some faster streets (the engine was so loud you can’t hear any other cars in the recordings), abusing the manual mode for higher rpm recordings the whole time until it started overheating, smoking and dumping liquid (coolant I think? Oil? Both?). I Quickly took the DPA out because it was right near a section of the engine that was overheating, but I left the NT5 in. Satisfied with what I recorded but still a couple miles from home, after my car cooled a bit I continued to record my drive home, this time with the DPA inside the car to get an interior perspective (this drive is labeled “bonus drive” in the library).

    This library is just 5 files, totaling 27 minutes and 28 seconds, 24/96k, 956MB. Quality Soundminer metadata and UCS compliant. Recorded with a DPA 4061 and NT5 for starts, idles, off, revving, slow to moderate driving, harder faster driving, with lots of variation. One file is just the NT5 engine recording for an additional 5 and a half minute drive, and one is just the DPA for an interior perspective of that drive.

    I’ll miss that car a lot, but at least I got some great recordings out of it! I hope you find them useful.
