% Steam Audio 4.0.3 % Valve Corporation
Steam Audio supports Windows (32 bit and 64 bit), Linux (32 bit and 64 bit), macOS, and Android (armv7, arm64, x86, x64) platforms.
Steam Audio supports Unity 2017.3+, Unreal Engine 4.16+, and FMOD Studio 2.0+.
I've upgraded to 4.0.1 from 2.0.20. I'm using Unity 2020.2.0f1.
The editor crashes extremely often now. After hitting the [>] Play button to test, there's about a 1/3 chance that it will crash.
The crash logs reveal that these crashes are always from within a Steam Audio related DLL, usually Phonon:
I uploaded the crash logs here. Crash_2021-09-22_020218439.zip
The scene most of these crashes occurred in involves a simple cube-shaped room with baked pathing and reverb. Probes are placed using custom code using the ProbeBatch and ProbeArray classes, though these crashes occur in levels without these things added.
Hi all,
I don't know if it is just me, but I cannot find a proper difference in the room acoustics when changing materials. For example, metallic materials should turn to a more reverberant environment because the attenuation rate is lower; with carpet material, the other way around. I have also tried the Custom material and, in my opinion, I can't see a difference.
Am I doing something wrong? Because that is not working for me.
Thank you!
Hi,
I'm developing gstreamer plugin based on phonon C API, I created 1st order test file that I'm able to play using iplApplyAmbisonicsBinauralEffect and it gets rendered properly, but if I try to rotate the the ambisonics data using: iplRotateAmbisonicsAudioBuffer before i apply the effect nothing happens to the data in the output buffer (tried both in place rotation and separate in and out buffers, rotator is initialized and rotation set). What I do looks more or less like:
//once at beginning: iplCreateBinauralRenderer iplCreateAmbisonicsBinauralEffect iplCreateAmbisonicsRotator
//each time the viewer moves/rotates iplSetAmbisonicsRotation // the quat is normalized.
//on each audio frame: iplRotateAmbisonicsAudioBuffer iplApplyAmbisonicsBinauralEffect
I tried rotation in each axis but it looks like the data remains untouched.
many thanks in advance

Hey there, I am using the new version of the steam Audio plugin with costum HRTF. I did everything described in the HTML file. Checked it several times, deinstalled and installed all plugins several times, but my costum HRTF won't load. When I type a random name for HRTF the "not found" error occurs, when using the name of a sofa file, no error occurs (as expected), but the used HRTFs are not my costum ones. To verify my problem, I used HRTF with time delays and also used HRTF with only zeros in it, but it seems that it doesn't change to my costum HRTF, instead using the default ones (but no error occurs, saying that the system switched back to default). I am using simpleFreeFieldHRIR Sofa conventions, as explained in the HTML file. Does anyone have a clue what I am doing wrong? Or is it a common error? Thanks for your help.
Hi, apologies in advance for opening an issue essentially to ask a question, I'm limited in terms of places to turn for guidance on this one!
I know this feature isn't technically supported, but I've been trying to this plugin to work with my own custom HRTFs in Unity. I think I sorta understand how it's supposed to work, from a combination of the guide posted on the page for the app on Steam and trial and error, but I've hit something of a dead end.
I have three functions (assigned to the _____callback variables in the HrtfParams):
public void onLoadHrtf(int numSamples, int numSpectrumSamples, Phonon.FFTHelper fft, System.IntPtr data)
public void onUnloadHrtf()
public void onLookupHrtf(System.IntPtr direction, System.IntPtr leftHrtf, System.IntPtr rightHrtf)
However, the problem is that I can't find any way to access my HRTF set once I've loaded it using onLoadHrtf! I've checked, as far as I can tell, every class in the Phonon namespace going entirely off Visual Studio prompts that pop up when I start typing "phonon."
I don't know if I'm misunderstanding the intended way of implementing this, or if it's actually impossible to get custom HRTFs working with this plugin at the moment, literally any tips/pointers would be so appreciated - I'm utterly stumped!
I have integrated Steam Audio 4.0.2 in my Unity project by installing the "SteamAudio.unitypackage". I am targeting Android (Oculus Quest 2) with the IL2CPP scripting backend.
By default, the target architecture of my project was initially set to ARMv7, and builds with this configuration ran just fine on the Oculus Quest 2.
However, I just changed the target architecture to ARM64 (recommended by Oculus due to performance) and this causes Steam Audio to completely stop functioning in Android builds. I am faced with a multitude of errors that are constantly streaming (unable to load DLL 'phonon'), no spatialized audio sources play, and the game sometimes crashes. What can be done to fix Steam Audio for ARM64?
See images below:
(Logs from the Oculus Quest were taken via Android Logcat in Unity)
I'm trying to implement Steam Audio together with FMOD 2.01. So far sounds work and binaural works as well but what doesn't work is any attenuation (all sound plays at the same volume at every single distance) and the reflections/occlusion don't work.
I've exported the scene and put a SteamAudioSource on it, but it simply refuses to work.
Is this a problem with FMod 2.0?
Hello
I'm very new to the world of Unity so there is a strong possibility I'm missing something glaringly obvious, but here goes!
Firstly, if this makes a difference, I am using Mac OS.
I'm trying to create and immersive sound experience, in which a user can move the player around and hear full 3D sound, complete with HRTF and have the materials of the room effect the audio sources eg echoes, occlusion etc. However, although I am getting a 3D sound as far as directivity is concerned, the geometry of the environment has no effect on my audio sources.
Following the documentation supplied by Steam Audio, I have created my project, imported the Steam Audio Package and selected Steam Audio for my Spatializer Plugin and Ambisonic Plugin.
After selecting Steam Audio from the Window tab, I have created my walls and floor using cubes, stored them in an empty object, and tagged the empty object with a Steam Audio Geometry component and selected Export All Children. Then, I have added Steam Audio Material component and selected Concrete (I thought this would give an obvious echo to test). The documentation then suggest Pre-Export Scene in Window>Steam Audio 'to ensure scene setup changes are available to Steam Audio'. I don't fully understand the importance of this so there might be something here where I am going wrong.
Once I have quickly create a player using a capsule and camera, I add a Steam Audio Listener to the camera, and create a Cube to attach my Audio Source to. I check 'Play On Awake' and 'Loop', 'Spatial Blend' is set to '3D' and check 'Spatialize'. After adding a Steam Audio Source to my cube, the setup in this component is; Direct Binaural - checked; HRTF Interpolation - Bilinear; Direct Sound Occlusion - On, Frequency Dependant Transmission; Occlusion Method -Raycast; Physics Based Attenuation - checked; Air Absorption - checked;
I also have Indirect sound; Reflections checked, simulation type at Realtime and Indirect Binaural checked.
Now, I don't believe there is anything I have missed but the materials in the space seem to have no effect on the sound.
Sorry if there is a lot to read through, but I didn't know a better way to describe it. I'm pulling my hair out as I can't see why this isn't working and I'm hoping it's a really silly mistake!
Any ideas?
Thanks in Advance
Hi, I revisited steam audio today, about 2 years later. It seems oclussion is still too agressive (No diffraction #9) and it also cuts of audio in wierd ways when moving through door ways and similar. What's the general state of the software? It seems it was a long time since project members were active here in the issue section?
Here I showcase some of my problems, steam audio 2 beta 17
https://youtu.be/77pR0z87-T4
In the Unity plugin, the Audio Source can be configured to use a non-physical distance attenuation curve, and the Phonon Effect can be configured to use that curve. However, sound propagation simulation does not seem to be using the custom attenuation curve properly.
When an audio source plays sound for the first time, spatial blend seems to default to zero and take a moment to update to the value set on the audioSource component. This results in a moment of very loud audio playing from even distant sources. Most noticeable when an audiosource plays well into a level load, e.g. an enemy spawns in and fires their gun.
We are using Unity Docker images from game.ci for building (actually, exporting native projects and then building on the target development OS). The image we are currently using is ubuntu-2021.3.3f1-android-1.0.1
When we try to use a reverb using SteamAudio, we get this segfault - which doesn't happen when we build manually on Windows.

Is Valve no longer working on this project for Unity?
There are some serious issues with the current branch, causing a lot of random crashes on loading. Last update was over 7 months ago.
Is any one else considering not even using Steam Audio for there Unity project? I am seriously considering removing it, because of this, and it's really disappointing.
Last few weeks I've spent the time updating a beta version of steam audio to the latest stable and there are a few things I wanted to bring up which stomped me with the implementation.
Under certain circumstances, simulations can fail or throw an exception within phonon without a clear indication of why it happens or what caused it. An example of this is attempting to bake a path without a probe batch. This ends up causing an exception within phonon without any feedback on why it happens.
Currently, if we need to fetch any information about a probe within a probe batch, there's no way to do this. We're able to fetch how many probes themselves exist within the batch, but we cannot any individual probes. In contrast, with a probe array, we're able to fetch information about any probe within it. This means to keep compatibility between versions we need to store a copy of all probes within our serialized steam audio file.
There's an inconsistency in the documentation for this. When specifying baking params for reverb, it's not stated anywhere that bakeBatchSize needs to be a non-zero value. Within the documentation this field makes note of Radeon Rays, however, the warning from the baker refers to this as "max sources"
When baking, we can specify a status/progress callback. There are situations where NaN can be passed to our callback function. This can lead to unexpected results when handling how far along the baking process is.
If you want to place one probe at a time within a probe array, there's no nice way to handle this. The workflow is to use iplProbeArrayGenerateProbes with IPL_PROBEGENERATIONTYPE_CENTROID, then add this to a probe batch. Calling iplProbeArrayGenerateProbes multiple times on a single probe array ends up replacing all the probes within the array. Having an option to append without deleting previous probes would make it more intuitive to use.
Loading serialized data overwrites everything within the probe batch already. There's no reason commit shouldn't be called here automatically as it's a major change. It's a bit counter-intuitive and caught me off guard.
There might have been a few other oddities I missed but if they come back to me I'll update the issue
When "Steam Audio -> Settings -> Scene Type" is set to Unity (in order to config the layers) the following exception is thrown when doing a bake on a SteamAudioProbeBatch or SteamAudioBakedSource
It is the same issue as reported here: https://github.com/ValveSoftware/steam-audio/issues/194 but that solution is not desirable. We still want to confiure which layers are used for raycasting.
This issue also sounds the same: https://steamcommunity.com/app/596420/discussions/0/3159832276060036018/

I've still noticed crashes after the 4.0.2 patch was released. They were a lot more infrequent, but they're still there - in both builds and the editor. A sore spot seems to be switching levels. There's a much higher chance of a crash occurring there. Perhaps SteamAudio classes are initializing themselves in an unexpected order? Perhaps they are being used before being initialized, or before other classes they depend on are initialized?
Here are crash logs I recovered for the editor in which Steam Audio was the cause: crash.zip crash2.zip
Current unity version: 2021.3.1f1 Current steam audio version: 4.0.2
The changes from 4.0.2 to 4.0.3 don't seem to contain anything that'd address this crash; changes are to:
(Though "Performance improvement in Ambisonics Panning/Decode Effect" doesn't appear in the diffs either.)
