There are two pieces of code needed here, and one utility. First is a program called track_rec. Track_rec is used to take input from a sterio system from whatever source. It is handy in that you can enter the names of the tracks on the interface, then simply press a button to have it start a new output file.
The second component to the Vinyl Project is Gnome Wave Cleaner. GWC allows you to amplify, denoise and declick the audio of any wav file. But was designed to deal with imperfect audio from old media.
The third component to the Vinyl Project is Wavlist. wavlist is like an "ls" for wave files, printing the filename, followed by the length of the audio track in minutes:seconds format, useful for importing into jewel case editors such as kover, or gcover.
WARNING
GWC and Track_rec are both beta code, back up your
data, we do not warrant that the software will work at all.
