Mix/Mux 2 .WAV files together into single file?

[mvalpreda]

I have a large amount of .wav files that are comprised of two channels of a recorded phone conversation. There is one file of the local side and one file of the remote side. I need these in one file and preferably something I can do with a batch.

What program might I use to do that? Thanks!

You can google for "mix wave files". Here is one freeware I found using that search:

I don't know how good it is. Others may give you more specific advice.

I saw that program as well. It does not appear to work from a command line.

I have thousands of files I need to mix.

Ah, well, your post did not emphasize that you needed a command line utility, it just said "preferable".

Have you looked into sox? Google "mix wav files sox".

Thanks. That was just what I needed.

sox -m file-in.wav file-out.wav file.wav

Most appreciated.
