Hi,

When burning an audio CD, I take it there are two limits i.e 80 minutes and 700MB. Whichever is reached first right?

Ta.:)

They are equivalent, 80 minutes of audio data is 700mb.

Ah I see. Cheers. Strange that though because I'm thinking you could compress that 80 min audio data to say 350MB but then that would mean I could fit another 80 minutes on...:confused:!!!

No, because an "audio cd" is in raw uncompressed audio, that oddly enough takes 700MB to fill 80 mins ;)

A data CD (ie full of MP3's) can be as much audio as you can fit on, so will all depend on bitrate and compression used.

For audio a cd spins at a certain rate so unless im confused you cant compress audio cd's only use biger/longer or smaller..
 
Just speed the track up, then you can get 160mins worth of ausio on an 80 minute disk.

Please note: Audio may sound slightly faster.

Only if your car head unit plays MP3 CDs ;)

44100 16 bit samples per second = 1.41 megabits per second. Unless you went with the original spec of CD (44.1k in 14 bit) you cant get any more audio onto a CD.

Incidentally, that only came about because of how good a sound philips had got with their 14-bit DAC so Sony moved the goalposts to give their kit a sonic advantage!
