I am using TarsosDSP library to apply a low pass filter on a wav file. Here is the code.
private void eq2(File file) throws FileNotFoundException {
new AndroidFFMPEGLocator(this);
InputStream inputStream = new FileInputStream(file);
TarsosDSPAudioFormat format = new TarsosDSPAudioFormat(16000,16,2,true,false);
AudioDispatcher adp = new AudioDispatcher(new UniversalAudioInputStream(inputStream,format),2048,0);
adp.addAudioProcessor(new LowPassFS(100,16000));
RandomAccessFile raf = null;
raf = new RandomAccessFile(Environment.getExternalStorageDirectory()+ "/cibiodLogs/audioFiltered1.wav", "rw");
adp.addAudioProcessor(new WriterProcessor(format,raf));
adp.run();
Thread audioThread = new Thread(adp, "Audio Thread");
audioThread.start();
}
It gives output but the output is choppy and not even filtered. Here take a look at the original wav file and the output wav file.
I have tried different buffer sizes from 2 - 4096 but every time either the output is choppy or the audio is not filtered. Can someone point me what might be going wrong here.
