在 Android 上使用 TarsosDSP 进行实时变调

Question

这是我想要的：
1. 播放歌曲时实时变调
2. 变调也应该记录到文件中。

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);

但是我遇到了以下错误：

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

第

行

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

如果我删除此行，一切正常，只是歌曲未录制到文件中。
如果有人可以提供帮助，请告诉我。

此问题已使用不依赖于 JVM 的 WriterProcessor class 解决。
