Since someone here has just mentioned .ogg files I was wondering what encoding rate I need to use so that I cannot distinguish my .ogg file from my cd. A couple years back I read about a double-blind (maybe just single blind) study with 256kbit constant bitrate mp3's. The listeners, who were described to have excellent ears, could not distinguish the mp3's from the cd's, though a computer could. I don't care what a computer can distinguish.
I have searched the net several times and found no similar study with .ogg files. Aren't there any people who have done a blind study with .ogg files? I want to know the minimum quality settings I can use with .ogg in order to save hd space. I have about 120gb 256kb mp3 music. According to my preliminary research I think I can save at least 30% space.
Thanks, Jeff
