Here is what I want :
1. Real time pitch shift while playing song.
2. Pitch shift should also be recorded to a file.
code :
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);
But here I am facing following error :
Error:(362, 41) error: cannot access AudioFormat
class file for javax.sound.sampled.AudioFormat not found
for line
WaveformWriter writer = new WaveformWriter((TarsosDSPAudioFormat) dispatcher.getFormat(), BASE_PATH + "Recorded" + File.separator + "PITCHED_" + mVideoFileName + ".mp3");
If I remove this line everything works fine only song is not recorded to file.
Please let me know if someone could help.
