Do yourself a favor and read a bit. The human ear does have it's limitations, and for example, why do you need the full spectrum for a recorded voice? That's just ridiculous.I.S.T. wrote:2 is a fallacy. You can train a motherfucker(or he can train himself) to hear the differences. Sound compression is not that good yet.
Mp3 is just one of many codings and has only middle quality, even surpassed by Ogg Vorbis. However, even Mp3 encoding is suitable enough for voice recording (which is what I think would take up most space there).I.S.T. wrote:Supposedly, LAME uses that type of psycho acoustic model when compressing(Might have my terms mixed up a bit here... Been a while since I read this stuff, and I am horrible at remembering names for things.), and we all know MP3s are easily beaten by many, many codecs.
Then again, how much losless audio is being recorded? 80 mins is around 800 mb, and without any compression at ALL (whereas losless codecs get this reduced to around 300mb).
