AudioZip is a lossless audio compressor developed at the Centre for Signal Processing - Nanyang Technological University, in Singapore, by professor Lin Xiao. The compression ratio is decent, but the compressor is quite slow.

The interface is quite unfriendly. Despite looking like it, there is no way to batch compress files. You have to click "Compress", select the .wav track, type the name of the compressed file (it does not just append the compressed extension), click "New" and then click again "Compress" after selecting compression level. For each and every file. Sometimes it crashes after clicking the second "Compress". All in all, it is a quite buggy program that feels rushed.

One unique feature of AudioZip among audio codecs is that there is an option to use a password at compression time to "protect" the compressed file. Decompression fails without the password. I put "protect" surrounded by quotation marks because the password is stored in plain text at offset 0x06 of the compressed file...
Certainly the work of accomplished cryptographers!

Compression performance in my limited test: 54,96% (maximum setting)
