I've used WavPack this time around for better (lossless) compression than simply RARing the WAV.
Unlike FLAC, WavPack preserves the extra RIFF chunks (bext, minf, elmo, regn, ovwf & umid) present in the original WAV from Belbucus.
Unless you also use ProTools audio software as Belbucus did, those extra chunks probably won't mean anything to you.
Nevertheless, I want to redistribute the files exactly as I received them.
APE also retains the extra RIFF chunks, but I like WavPack's open-source licensing terms better that Monkey's.
