在Android上使用TarsosDSP实现实时音高变换

以下是我想要的：
1.播放歌曲时的实时音高变化。
2.音调偏移也应记录到文件中

代码：

    double rate = 1.0;
    RateTransposer rateTransposer;
    AudioDispatcher dispatcher;
    WaveformSimilarityBasedOverlapAdd wsola;

    dispatcher = AudioDispatcherFactory.fromPipe(mAudiopath, 44100, 5000, 2500);
    rateTransposer = new RateTransposer(rate);
    wsola = new WaveformSimilarityBasedOverlapAdd(WaveformSimilarityBasedOverlapAdd.Parameters.musicDefaults(rate, 44100));
    WaveformWriter writer = new WaveformWriter((TarsosDSPAudioFormat) dispatcher.getFormat(), BASE_PATH + "Recorded" + File.separator + "PITCHED_" + mVideoFileName + ".mp3");

    wsola.setDispatcher(dispatcher);
    dispatcher.addAudioProcessor(wsola);
    dispatcher.addAudioProcessor(rateTransposer);
    dispatcher.addAudioProcessor(new AndroidAudioPlayer(dispatcher.getFormat()));
    dispatcher.setZeroPadFirstBuffer(true);
    dispatcher.setZeroPadLastBuffer(true);
    dispatcher.addAudioProcessor(writer);

但在这里，我面临以下错误：

Error:(362, 41) error: cannot access AudioFormat
class file for javax.sound.sampled.AudioFormat not found

用于线路

   WaveformWriter writer = new WaveformWriter((TarsosDSPAudioFormat) dispatcher.getFormat(), BASE_PATH + "Recorded" + File.separator + "PITCHED_" + mVideoFileName + ".mp3");

如果我删除这一行，一切正常，只有歌曲不会录制到文件中。

请告诉我是否有人可以帮忙。

这个问题是使用WriterProcessor类解决的，它不依赖于JVM
