 I use myplay and rmplay scripts (see scripts subdirectory). The first one is a
 simple wrapper for interactive sox. The second playes consecutive files
 matching the pattern and detects Q (finish), and B (go to the previous file)
 commands.

 - socket communication (instead of pipe)
 - output should not appear on the screen but should be redirected to the socket
