How to convert .pcm file to .wav or .mp3?

Question

I am currently developing an Android Application that has audio recording and playing. I am new to dealing with audio and I\'m having some trouble with encoding and formats.

Answer 1

Just to register, I solved my need of recording an audio playable in common players using MediaRecorder instead of Audio Recorder.

To start recording:

    MediaRecorder mRecorder = new MediaRecorder();
    mRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
    mRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
    mRecorder.setAudioEncoder(MediaRecorder.OutputFormat.AMR_NB);
    mRecorder.setOutputFile(Environment.getExternalStorageDirectory()
                .getAbsolutePath() + "/recording.3gp");

    mRecorder.prepare();
    mRecorder.start();

And to play the recording:

    mPlayer = new MediaPlayer();
    mPlayer.setDataSource(Environment.getExternalStorageDirectory()
                .getAbsolutePath() + "/recording.3gp");

    mPlayer.prepare();
    mPlayer.start();
