Save audioClip to MP3

!WARNING!
Probably, saving to mp3, broken for Unity 2020+. But all other stuff working
FormatException: Not a WAVE file - no RIFF header
Sorry, no time to look into that

With this package you can save an audioclip to mp3 in unity3d. Also plugin can save audioclip to wav and convert wav to mp3.

It works with Windows, Android and IOS(tested). And probably on Mac(untested, but should work).

Lame unity port from https://github.com/3wz/Lame-For-Unity
Wav save script from https://gist.github.com/darktable/2317063

Convert audio clip to mp3 bytes array. For example to send it via network:

public AudioClip clip;

void Start(){
// Convert wav clip to mp3 bytes array
//128 is recommend bitray for mp3 files
byte[] mp3 = WavToMp3.ConvertWavToMp3(clip, 128);
}

Save AudioClip at path with defined bitray as mp3

// THIS METHOD PROBABLY BROKEN FOR UNITY 2020+
public AudioClip clip;

void Start(){
// Save AudioClip at assets path with defined bitray as mp3
//128 is recommend bitray for mp3 files
EncodeMP3.SaveMp3(clip, $"{Application.dataPath}/mp3File", 128);
}

Save AudioClip at path with as wav

public AudioClip clip;

void Start(){
// Save AudioClip at assets path as wav
SavWav.SaveWav($"{Application.dataPath}/wavFile", clip);	
}
