Ecasound even lets you record and encode directly to mp3, so you can record
for LONG periods of time without needing too much disk space. (I suspect
-z:db here really is the magic trick for the whole thing to come smoothly.)
I used to record my jams on tape so that I could listen to them afterwards
to look for good melodic lines and song ideas in them. Now I just do it
with ecasound. :) Real time encoding (with lame) doesn't even suck up too
much CPU time!
