Frequently asked questions
Will reversing lose original quality?
WAV keeps the decoded PCM samples; MP3 applies lossy compression according to the encoder settings.

Yes. Each channel is reversed independently while preserving the channel count.
Why cannot some files load?
decodeAudioData support depends on the format and platform. Try a common WAV or MP3 file first.
