Date issues aside, I suggest compressing the .wav files with an audio
codec. If you don't want to loose any information to a lossy codec,
try FLAC. It is lossless like gzip, but it should give somewhat better
compression than a non-audio-specific compressor. And of course
something like vorbis on q4-q6 will give very good sound and give much
smaller size, if you don't mind lossy.
