alsa and sox questions

[Charles Hallenbeck]

Greg -
The alsa 0.9.0beta11 archives are there where the others are, but
since they are placed in alphabetical order they are not near the
end of the list. Use the Lynx search command to search for
"beta11" and you will find them.

The alsa "arecord" command will generate two files from a stereo
source if you want it to, one for the left and one for the right.
It appends a ".0" to one and a ".1" to the other. They seem to be
".raw" files rather than ".wav" but you can easily convert them
with sox.

I think this is defined as left and right channels, but if this isn't correct, please assume that it is throughout this post. Based on reading the sox man page, I think I can do the following, but I need someone to reassure me.

What I'm asking is if I record this tape as a wave file, can I then strip either the left or right channels from this recording?

Yes, it is for a purpose, and depending on what answers I get, I may or may not do what I'm planning, it really is a long story. Thanks for bearing with me, and for any help in advance.
