Use Sox to Make a File Mono

Kernel 2.6, GNU (Slackware 12.0).
sox 12.18.1

Hi:

Code:

bash-3.1# file receive48.wav 
receive48.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, stereo 48000 Hz
bash-3.1#

This file, I intend to make it mono. That is, to mix both channels. I know this is a piece of cake for sox. But exactly how do I do it?

More descriptive thread titles are courteous, helpful and more likely to attract expertise.

You've been a member for over 3 years now, and with more posts than I've managed since I've been here. You ought to know better, dude. To answer your question, you could probably average out the channels in the stereo. Something like:

Code:

sox receive48.wav -c 1 receive48_mono.wav avg
