I'm trying to use bandpass filter to filter out music from music+voice stream. Audacity does using FFT and Noise Gate you can see youtube for example. As I understand how basepass works, it should similar job just fine. Passing:
f = new TarsosDSPAudioFormat(info.hz, 16, info.channels, false, false);
b = new BandPass(1650, 2700, info.hz);
But results not what I expected, seems basepass does not filter correct band frequencies.
