cdcover by rjp

cdcover analyses MP3s and other audio files, generating a picture of the waveform for each track, suitable as "album art" for an ID3 tag, or for combining as a single "CD cover"

Wholly inspired by Joshua Distler's "Music CD Labeling System" with prompting from Mr P.Mison

Sample output

How to run it

./process.sh [flags] [list of audio files]

Options

-o /path/to/output
--outputdir /path/to/output: Output directory
-s
--scaling: Scale to the longest
-w N
--window N: Moving average over N pixels
-m
--montage: Make a 4x4 montage of 150x150 versions
-e
--outline: Outline output
-x
--spiky: Spiky output
-f
--force: Force update of the png

Example

To convert a bunch of mp3s into ./png/esquivel/*.png output files...

./process.sh -e -s -f -w 5 -m -o png/esquivel esquivel/*.mp3

Dependencies

sox, mp3info, ruby, rmagick

Tested with sox v14.0.0, MP3Info 0.8.4, ruby 1.8.6 (2007-09-24 patchlevel 111), RMagick 2.9.1.

It does somewhat assume you've installed RMagick using rubygems and will probably break if you don't have rubygems anywhere. Easily rectified by deleting the first line of cdcover.rb.
