我可以将wav文件转换为pcm

ffmpeg -i file.wav -f s16le -acodec pcm_s16le file.pcm

我该如何恢复此操作？

@Override
public void onCreate(Bundle savedInstanceState) {
...
        mMediaPlayer = new MediaPlayer();

        mMediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
            public void onCompletion(MediaPlayer mediaPlayer) {
                playAudio(getNextAudioFile());
            }
        });
..
}

@Override
protected void onDestroy() {
    super.onDestroy();
    if(mMediaPlayer != null) {
        mMediaPlayer.release();
        mMediaPlayer = null;
    }
}
    private boolean playAudio(String file) {
        if(file.isEmpty()) {
            return true;
        }

        if(mMediaPlayer.isPlaying()) {          
            mMediaPlayer.stop();
        }
    mMediaPlayer.reset();

        mAudioFile = new File(mBaseAudioDir, file);
        if(mAudioFile.canRead()) {
            try {
            mMediaPlayer.setDataSource(mAudioFile.getPath());
                mMediaPlayer.prepare();
            } catch (IllegalArgumentException e) {
                return false;
            } catch (IllegalStateException e) {
                return false; …
