m3udo allows you to apply a command to each line of a text file in the M3U format. It is similar to the xargs command, except that it supports of number of niceties useful for batch processing. Things you might do with it include moving a collection of files to a common directory, converting all files from one format to another, or calculating FFTs of an entire album.
fantastic. I am blown away.
There is nothing like it.
...given that you have a large enough collection of MP3s to let a power tool like this show what it can do, and given that you're at home with a shell interface.
good despite rawness
* defaults are still not so sensible.
* for one cd I ripped there were a lot of problems. Don't know yet if this was LAME or CDR...
* a lot of chrome still to go.
Second good stuff:
* the code is easy to patch. I found and fixed a dumb default in < 5 minutes.
* the look and feel is sweet.
* modularity of design (e.g. using Pico to edit playlists) makes CDR fit nicely into a unixy working mode.
Overall I like it and have no plans to find another ripper.
