CLICK DETECT version 0.16, september 28, 2010, Pieter Suurmond.
  Latest version available at: http://kmt.hku.nl/~pieter/EDU/c/cd_click_detect/

  A small (bash) shell script plus a small C program to find ticks and glitches
  in a large collection of WAV- or AIFF-files (that were ripped from audio-CD).
  In case of WAV files, you need the SOX program to be installed.

  For example, the following may happen when you extract from audio-CD
  (but unfortunately none of the CD-ripping softwares complains about it!):

  

  First compile the C-program with for example:

            gcc -O3 -Wall click_detect.c rdaiff.c -o click_detect

  Shell script 'click_detect_wav' doesn't need to be compiled. It expects WAV
  files and calls sox to convert them to (temporary) AIFF files, which are then
  checked for ticks and glitches. To inspect a directory, type something like:

            ./click_detect_wav /media/TERABYTE_2/wavs

  When ticks or clicks are suspected, the program reports them like this:

    CONSTANT DC (47 for 1703 samples) in channel 1 at frame 416953 (9.493 s).
