    Re: Stereo to mono conversion

    What kind of file? If it's wav or some other non-compressed PCM format, you can read each sample from each channel and average the two channels into one and save it off to a mono PCM file. If it is a compressed file, you'll need to decompress to PCM first.

    Sox is an open source audio toolbox so you could take a look at how they handle it if you want the details:
