Re: [SoX-users] Keep multiple files AND merge into one file

[Ryan D. <ry...@ju...>]

Jan,
Thanks for the reply. Please see my reply to Erich. Hopefully that will
clear up what I'm trying to accomplish.

In reply to one of your concerns, yes, the master.mp3 file would only be
for *one* day's worth of transmissions, so the file should not get to
uncontrollably large (the stream is not very active).

I currently have a bash script which watches the transmissions directory
and for every new file it renames the file based on modification date and
moves it into a new dir based on the day's date.
