BTW, FFmpegFrameRecorder does support audio conversion, so it should be
possible to refer to it and do something similar in FFMpegFrameGrabber.

Hi, I'm desperate, I do not get sound on this file to sound good. The ringing
sound is full of noise. Can someone help me out? or show me how I do it? Thank
you very much.
FFmpegFrameGrabber grabber = new FFmpegFrameGrabber("c:\\com4j\\video.avi");

grabber.start();
CanvasFrame cff = new CanvasFrame("Playing");
System.out.println("Caneles de audio: " +grabber.getAudioChannels());
System.out.println("Samplerate: " +grabber.getSampleRate());
System.out.println("getSampleFormat: " +grabber.getSampleFormat());
//AudioFormat audioFormat = new AudioFormat(grabber.getSampleRate(), 192, grabber.getAudioChannels(), true, false);
AudioFormat audioFormat = new AudioFormat(grabber.getSampleRate(), 16, grabber.getAudioChannels(), true, true);
DataLine.Info info = new DataLine.Info(SourceDataLine.class, audioFormat);
