Lossless compression of _not_ the samples,
but the rest of the module-data?
Lossless compression is a term used for Sound Or Video Compression (Most often sound) which means that you
"compress", remove parts of the sound/video which is
impossible to hear/see anyways - which means that you
decrease the file-size withouth losing anything...
When it comes to data (Not sound/video) it's quite pointless,
to not say impossible, to "compress" (in reality remove) parts of it in this fashion - since any little lost information counts when it comes to 1 and 0's..
