You can use any regular MP3 codec API to decode a stream, work with it and save it again. For example, you can use libLAME for this part.

Answer 5

Very good C ++ STK audio / synthesizer library . It downloads a lot of things and is under a license like BSD / MIT, that is, you can use it to develop commercial products. Wav is supported, but not MP3. For example, for MP3 you can use irrklang , which is free for non-commercial use (also MAD by underbit, used by human loads).
