Command line interface to make a ogg mono from stereo

Question

Is there a command-line interface I can use to make one or more ogg-music-files into mono?

Answer 1

You can use it with oggdec and oggenc. In good old unix fashion, the decoding and encoding process is separated, so oggenc cannot take ogg as input. However, it is straightforward and easily combined in a shellscript if so desired.

oggdec myfile.ogg
oggenc --downmix myfile.wav -o myfile_mono.ogg
rm myfile.wav

If you wish to control the output quality, run oggenc with the -q flag with a value from -1 (very low) to 10 (very high)

Answer 2

sox is a nice tool for all sorts of command line audio processing

sox your_inputfile.ogg your_outputfile.ogg remix -
