alsa and sox questions

[Charles Hallenbeck]

I tried that, Jim, but I still got raw files. I have not played
with it a lot myself, so perhaps I screwed it up while checking
it out or something. I went to the beta11 version of alsa because
the last time I looked there had not been a beta12 version of the
alsa OSS package posted.

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.
