getting your "session" onto a CD?

[surferdeac]

Was just wondering how to go about copying / burning a sessions given info once you are satisfied with it onto a cd. Is there a reccomeded format to do so with?? can you burn your session onto a disk in - mp3 format; or avi format , or Wav; what i am trying to get at here is there one way thats better than the other in order to optimize or retain the overall sessions audio quality onto a audio cd. I have recorded most all of my sessions in 48khz in 24bit sample format, and have been informed that when you mixdown or convert your audio from a session onto a Cd that it automatically converts Down to 44.1khz???? Will i still Retain a 24 bit quality or does that get converted down to 16 bit as well.

---Also i have heard that sometimes if you create a session at 48khz and you have to convert it down to 44.1 khz to get it onto a disk that your "overall audio track length can be affected????-----

anotherwords once you have converted your session onto a cd and if you were to simutaneously playback you session on your computer at 48khz, with a burned version of that session on a cd at 44.1 khz that they would playback at slightly different speeds. Is this True?????????

You click on File and then bounce to Disk and then as far as I remember you can choose the sample rate and bit depth and whether you want it to be Stereo, Mono Summed or 2 Separate Mono Files. You need to bounce it as 16 bit and 44.1 kHz if you're going to burn it to an audio CD.

is any burning medium that can capture you session at 48khz at 24 bit or even can you get 44.1 at 24 bit instead of 16 bit onto a CD
???

[irishharry]

No, every CD you have ever listened to has been 16 bit.


A DVD contains 24 bit audio.


You wont notice any difference. I promise.

thank you IrishHarry!!!!!!!

Audio CDs are always 16 bit, 44.1kHz. Video DVDs are 16 bit, 48kHz. The only discs that I know of that can play back 24 bit audio are DVD-A, SACD and Blu-ray.

I think there are benefits to recording, mixing and mastering in 24 bit before going to 16 for the CD, so don't feel like you've wasted resources.

A 48kHz file played back at 44.1kHz will play slightly longer than at 48, but you will be converting to the new rate (not simply playing back at it) so the tracks should retain their original length.

last question i promise. So if you make a session in pro tools at 48khz at 24bit, when you convert down to 44.1 at 16 bit to get onto a cd, is the conversion going to effect how fast your CD will play back the audio from your original session at 48khz at 24 bit??

[surferdeac]

oh ok gotcha

Actually SACD is 1 bit, but the quality is equal to 24 bit thanks to the insane sample rate.

Recording at 24 bit/48K is fine. When you bounce to disk, if the goal is to send the final mix to be mastered, stay at 24/48 and let the mastering house provide the final version for replication(16 bit/44.1K for an audio CD). If you want to burn audio CD's yourself(even if just for reference), then you need to dither(from 24 bit to 16 bit by inserting a dither plugin on the master track in the last slot) and sample rate convert to 44.1K(just select 44.1K in the bounce window). Now when I bounce, I usually stay at 24 bit and dither in a separate step by importing the final 2 mix into either WaveLab or Pro Tools. That's where I trim the head and tail, add a fadeout if needed, and add dither(and maybe some mastering limiter). By doing all that separately, the bounced file(from the session) is ready to go to mastering as is. A lot of Mac users use Toast for audio CD burning(but you still want to use a 16 bit/44.1K file). Sample rate conversion will not affect the length of a song(playing a 48K song at 44.1K WILL be shorter and higher pitched. The opposite would happen for a 44.1K file played back at 48K).
