Resolution Note:
The submitted project was not accessible and the user is unreacheable (invalid email). Since we could not try with the user's project or audio files, we made our own test project to explore the different audio asset conversion paths for WebGL by:
* Generating tones in the .wav, .mp3 and .ogg formats
* Testing them for our 3 compressions settings (ADPCM, PCM, Vorbis)
* Building with the 3 WebGL options (Shorter Build Time, Runtime Speed, Disk Size)
After multiple attempts, we were never able to reproduce the issue described (audio spikes appearing after conversion).
We believe his issue might have been linked to a corrupted original audio file or to an unsupported version of the AAC converter (Windows Media Foundation) on the user's machine.
