Branching from the MP3/AT3 (lossy) Compression thread Damien posted, this is similar, but is done with the FLAC (lossless) audio compression technology (suggested by @Zoku).
A suggestion from @_caustic_ is to drag & drop the folder ala-Moresampler style. (drop into the encode.bat the whole VB.)
Check the additional Information URL for instructions for decoding.
This part is made by me alone. I do not speak in behalf of Damien for this one.
