I've used Javazoom project for decode MP3 files: *Decoder decoder = new Decoder();* Next we can get stream of bytes: *Bitstream bs = new Bitstream(fis);* **Frame** is small part of file, for *.wav* files a frame is a signal, for *.mp3* files signal is encoded, so we can:
read header of frame:
*Header header = bs.readFrame();*
decode frame:
*SampleBuffer sBuffer = (SampleBuffer) decoder.decodeFrame(header, bs);*
and close frame:
*bs.closeFrame();* Now we can read array of bytes:
*short[] buffer = sBuffer.getBuffer();* Voila
