Record voice and save it to mp3 file

Is it possible to record (5 seconds) a voice with the microphone and save it as a mp3 file WITHOUT sending data to the server? I would 开发者_如何学Golike to save the file with FileReference (some times ago I did an experiment saving a bitmap and it worked).

You can use MicRecorder class for recording the sound, and as3lameencoder for encoding the recorded byte stream into mp3.
