cd question.

[%seRge%]

I've been having trouble keeping my 74-80 minute mixes under 700mb.
Whether I record live into soundforge or import from a cd, I always end up with a total file size of about 740mb...and this is without any type of processing or tweeking.
My computer will play these "overburned" cd's fine; I only run into trouble on consumer cd players. The last track ussually skips or has dropouts.

The file size decreases if I drop the bit rate to 16 but once the files get into nero they still show up over 700mb. WTF??
Should I compress my 78 minute, 44.1 khz wav files to 32 khz ?


Tips ?
Ideas ? graemlins/conf44.gif


thanks people

A "consumer" audio CD (Red Book standard) is always 16 bit, 44.1 kHz, up to 74 minutes. Anything longer, and it won't be compatible with all CD players. Many newer ones will continue to play past 74 minutes, and some play other formats besides Red Book (like .mp3s), but the majority of players out there are limited to the standard.

Changing the bit or sampling rate of your source file doesn't make any difference, because when you burn to audio CD, it is converted back to 16 bit, 44.1 kHz. Changing the rates only decreases your sound quality. Unless you really know what you are doing, you should record mixes you intend to put on CD at 16 bit, 44.1 kHz for the best sound.

Either keep your mixes < 74 min or make some of your audience live with the skipping at the end. Those are really your only options for standard audio CDs.

First off 1 stereo minute is 10.585 MB/min. So a sound file of 74 min is 783 MB and a 80 min is 846 MB. Now when a cd is used for audio only, the data is written to the cd differently than it would for data & audio. That's why a 74 & 80 min cd can have more than 650 or 700 MB written on them.

If you're recording to your PC first,119 minutes and 55 seconds is my standard.

Anything over that may be too large to fix and it's a pain to edit just a couple of seconds off of such a large file.

Peace
