ripcheck

ripcheck runs a variety of tests on WAV files to try to detect common CD ripping errors, including:

1) a short click at the beginning of a WAV file

2) the occasional dropped sample (i.e. a sample value of zero) in the middle of a song. This might be audible as a click as well.

3) the occasional repeated sample value, for about 1/1000th of a second. This would be audible as a very short tone.

4) the occasional empty spot in the middle of a song.

Two versions of ripcheck are available:

A) a very fast C version which displays warnings as text. We're providing compiled versions of the program for Mac and Windows. On Unix/Linux, compile from source with the command "gcc ripcheckc.c -o ripcheckc"

B) a much slower Tcl program, which makes pretty graphics of the WAV audio data around a probably defect, zooming in on each one.

Note: this program will display warnings on audio files that are sometimes perfectly ok, especially on highly processed electronic music.
