Assuming the audio is in stereo, how to extract the left channel and right channel ?

[Mhuang77]

import org.bytedeco.javacv.*;

public class TestMain {
    public static void main(String[] args) {
       // Replace with your audio file path
        String audioFilePath = "test.mp3"; 
        try (FrameGrabber grabber = new FFmpegFrameGrabber(audioFilePath)) {
            grabber.start();
            Frame frame;
            while ((frame = grabber.grab()) != null) {
                // Assuming the audio is in stereo, extract the left channel and right channel
                // TODO extract the left channel and right channel <------ ?
            }
            grabber.stop();
        } catch (FrameGrabber.Exception e) {
            e.printStackTrace();
        }
    }
}

I searched the Frame class methods but did not find a way can extract the left channel and right channel.

There's some sample code for that here thanks to @steeveen: https://github.com/bytedeco/javacv/blob/master/samples/AudioSplitMergeHelper.java
