hi guys

im making a mix cd for personal use, i want to fit a few more tracks on the cd without making shorter mixes.

at the moment i work on a mac and record in aiff format, ive noticed if you change the sample rate it alters the mb size slightly.

i did a little test
1 at 44100hz and it came to 90 mb
1 at 43000hz and it came to 87 mb

would i lose a great deal of sound quality thats noticeable by altering the sample rate.

does anyone have any other suggestions....

hope im making sense...

use 44.1

Standard and helps people who USE your mix.

I've had people send me 48khz and I have to sample rate convert to 44.1 to use it on the god damn radio.

yes as the last poster said use 44100, this is the standard sample rate for cd audio

thanks dudes

i know thats the standard, what im mean is would i notice that much difference if i did it at 42.000 instead

sample rate doesn't affect length of time on your CD. This is your original question correct? you can sample at 44.1kHz or 48kHz or whatever...but the length of the audio is not affected. similar to how an 128kbps mp3 and a 256kbps mp3 is still xx:xx long but vary in size.

as for how the quality is affected....I'm not too sure. Never tried, but I doubt 44.1 and 43 kHz will vary that much. however, when you burn audio to CD, 16bit/44.1kHz is the standard and actually, I'm not too sure if you can burn in any other sample rate and play it on your CD player.

hope this makes sense.

No you wouldnt, but in order to burn to an audio cd the audio will have to be resampled at 44100. Essentially this means converting the audio back to an audio waveform and resampling it at 44100 (of course its all done digitally). Everytime resampling like this occurs you lose quality, for the tiny gain of a few mb of space its really not worth it, just stick to 44100.

Did this answer the question any better?

ok i think i have a better answer

When burning an audio cd the file size means nothing, all that matters is the length of time of the audio.

Its late at night so i hope my posts are making sense :P
