actually on reflection it might be due to the audio file size
wav files are notoriously big
try converting it to an mp3 this will be much smaller, try a bitrate of 192kbs, decent sound but small file
im not sure what prog ur using to convert cd to audio, but check if it has a quality setting for the conversion, reduce this
BG: since your here, i meant to ask you ages ago for some Glenn Millar, big band music, so far ive went back as far as Chuck berry, but next stop is big band
if you could send me some or give me some pointers
