Web Audio API - record to MP3?

Question

I am asking because I couldn\'t find the answer anywhere. I have successfully implemented RecorderJS in order to record microphone input in JS. However, the recorded file is WAV

Answer 1

Encoding into smaller formats is currently only supported by Firefox:

• https://developer.mozilla.org/en-US/docs/Web/API/MediaRecorder

Chrome Firefox (Gecko) Internet Explorer Opera Safari (WebKit) Not supported 25.0 (25.0) Not supported Not supported Not supported

AFAIK only OGG is supported. But better OGG than WAV.
