I have an aiff file that in Preview is 102MB. The duration is 01:20:54. I understand that a regular cd cannot hold more than 79 minutes of stereo hi fidelity sound. As you can see from the data, my file is a lo fi digitally recorded speech. It seems to me that the duration takes precedence over the reality of the 'number of bits' which is still 102 mb to be burned on a disk that has 701mb available. Tried Toast, Dragon, i-tunes. OSX 3.9 3g ram

If you're burning as CD Audio, then all the matters is duration. Irregardless of the quality of the original file, everything is converted to CD Audio (44.1kHz whatever). Before it could be burned as CD audio your CD burning program would have to convert it to the format used for Audio CDs, resulting in a file size of about 710MB.

You can burn it as a 102MB file on a data CD, but then you'll only be able to play it in computers (i.e. not in standalone CD players).

Hi, f100, it is 102MB in Get Info. mduell, many thanks for your clarification, I did not realize that when I select Audio CD everything gets converted to the 44.1kHz format no matter what the original file size and type is. Very helpful
