Hi All,

my wav file is multi channel, how can I use FFmpegFrameGrabber to get a specific channel and write it into an output wav file ?

Thanks a lot

The easiest way to do that is probably with the ffmpeg program: http://bytedeco.org/javacpp-presets/ffmpeg/apidocs/org/bytedeco/ffmpeg/ffmpeg.html https://trac.ffmpeg.org/wiki/AudioChannelManipulation
