Question

我正在录制男声，当我点击播放按钮时如何将男声转换为女声并以女声播放。我引用了一些我试过sound pool的链接，通过改变浮动速率来改变声音，但我没有得到女性的声音，也没有改变音轨的频率。

这是我的代码：

           soundPool = new SoundPool(10, AudioManager.STREAM_MUSIC, 0);
            soundPool.setOnLoadCompleteListener(new OnLoadCompleteListener() {
              @Override
              public void onLoadComplete(SoundPool soundPool, int sampleId,
                  int status) {
                loaded = true;
              }
            });
            soundID = soundPool.load(mFileName, 1);


            AudioManager audioManager = (AudioManager) getSystemService(AUDIO_SERVICE);
              float actualVolume = (float) audioManager
                  .getStreamVolume(AudioManager.STREAM_MUSIC);
              float maxVolume = (float) audioManager
                  .getStreamMaxVolume(AudioManager.STREAM_MUSIC);
              float volume = actualVolume / maxVolume;
             /* if (loaded) {
                  iv.setImageDrawable(getResources().getDrawable(R.drawable.palyrec));
                  soundPool.play(soundID, volume, volume, 1, 0, 1.8f);
                  Log.e("Test", "Played sound");
              }*/
              int streamID = -1;
              do {

                  iv.setImageDrawable(getResources().getDrawable(R.drawable.palyrec));
                  streamID = soundPool.play(soundID, volume, volume, 1, 0, 1.7f);
                  Log.e("Test", "Played sound");


              } while(streamID==0);

更改频率代码： Integer [] freqset = {11025,16000,22050,44100};

   File file = new File(Environment.getExternalStorageDirectory(), "test.pcm");

    int shortSizeInBytes = Short.SIZE/Byte.SIZE;

    int bufferSizeInBytes = (int)(file.length()/shortSizeInBytes);
    short[] audioData = new short[bufferSizeInBytes];

    try {
        InputStream inputStream = new FileInputStream(file);
        BufferedInputStream bufferedInputStream = new BufferedInputStream(inputStream);
        DataInputStream dataInputStream = new DataInputStream(bufferedInputStream);

        int i = 0;
        while(dataInputStream.available() > 0){
            audioData[i] = dataInputStream.readShort();
            i++;
        }

        dataInputStream.close();

        int sampleFreq = (Integer)spFrequency.getSelectedItem();

        AudioTrack audioTrack = new AudioTrack(
                AudioManager.STREAM_MUSIC,
                sampleFreq,
                AudioFormat .CHANNEL_CONFIGURATION_MONO,
                AudioFormat.ENCODING_PCM_16BIT,
                bufferSizeInBytes,
                AudioTrack.MODE_STREAM);

       audioTrack.play();

audioTrack.write（audioData，0，bufferSizeInBytes）;

如何在android中转换为女声？
