I used Audacity to create mono "audiobook" files (such as can be heard here), and want to create an audio CD from them for submission to CreateSpace.
They, though, require that the files be in .AIFF format (easy enough for me to save my mp3 files as AIFF) and also 2-channel stereo, to wit:
Accepted digital formats
Uncompressed AIFF (44.1 KHz, 16- bit, 2-channel stereo files required)
The files are already 44.1 KHz, but are not 16-bit (they are 32-bit float), and are mono rather than stereo.
How can I convert my mono files to stereo (even though I realize the "other" side or channel will simply be a "carbon copy" of the original mono track?
I've tried saving one file as a left channel, and another as a right, and combining them, but don't see how to make that work in Audacity.
I tried File > Import > Audio..., but that doesn't seem to be the ticket.
UPDATE
Okay, I was finally able to copy a mono track to another (the first track was stereo, and had to change it to mono first); now, though, how can I save those two mono tracks as stereo? I see no "Convert to Stereo" menu option...
If I go to save these two tracks as an .AIFF file, it tells me that they will be saved as a single mono track...
