Bounce to disk sample rate

[royalb]

ok using protools and im recording and mixing at 24 / 48 so my question is when i bounce my session to disk as .wav and select 16/ 44.1 what do i do to maintain the sound of my 48k session>?

[slidey]

what is your purpose for bouncing in the 1st place, because to bounce onto CD it has to come down to 16@44.1

otherwise you should be able to bounce into 24@48

[royalb]

well i want to put it on a cd and i know cds only support 16/44.1 but i mixed it at 24/48 so once i bounce it at 16/4.1 its plays slooooooooow.
Im new at this but slowly im learning....thanks


im using a
ma200->sessionpack220->rossetta800->002r->rossetta800->centralstation->Bm15a's-> ME

you just need to bounce it to 44.1/16 and add dither to your master track to help with the bit depth correction.

if you're playing the bounced 44.1 file back through the Rosetta 800, you need to change the sample rate on the Rosetta to 44.1

ok so your saying

take my pt session that i recorded and mixed at 24/48 and bounce it to disk
at 16/44.1 as a stereo .wav. Then start a new session at 16/44.1 and import audio to track(the bounced .wav) at which point i will use the dither plugin on that track. then what?


im sorry but i just want to burn cds so i can do comparison tests on different systems.


thanks so much

no, in your 48kHz session create a new track and make it a stereo master fader.
Then on the last insert on that track, select the dither plugin. This will add dither to your signal...then bounce to disc as a 44.1Khz, 16 bit file....then burn that to CD.

ok thanks alot for your help
i tryed what you said but i still keep running into the problem of a slooow
song.

where are you listening to it back at? You've burned it to CD and taken it to a car or something and it still sounds slow? Or are you still listening to it back on the computer?

also, when you're recording you have your Focusrite set to 48kHz (if you're using the digital outs on it), your Rosetta set to 48kHz and your Pro Tools session set to 48kHz, correct?

[royalb]

yes the rosetta is set to 48 as well as protools(evrythings clocked to the rosetta)

and yes i am using my cars cd player..

the dither plug im using(protools factory) only has the option to change bit resolution which i have set at 16

[royalb]

i even tryed changing the sample rate to 44.1 on everything before i bounced it to disk but still no results...

In Pro Tools when you select "Bounce to Disk" a dialog box comes up. I don't have it in front of me now, so I can't remember exactly what it looks like, but somewhere in the window is a check box for sample rate conversion, and a drop down menu that sets the speed and quality of the conversion process. The slowest speed and highest quality is called "Tweak Head", and that's the one you want to use for best audio results.

Most computers are fast enough now that even Tweak Head doesn't take all that long - but I remember many years ago when I had a Mac Centris and I would have to schedule sample rate conversions around my lunch break.

If your audio is playing back slow and in a lower key, it means you never successfully converted from 48k to 44.1, so your CD player is basically playing a 48k file at 44.1 speed.

If you still can't get it to work right, PM me. When I'm in my studio and in front of my PT system I can walk you through it. I've had to do what you are trying to do all the time (usually with stuff originally recorded on 48k ADATs), and it shouldn't be a problem.

the conversion quality isn't what is wrong with it, that just tells Pro Tools how much work it should do to make sure it's converted perfectly...and he's already said that he's selected the "bounce to sample rate" as 44.1kHz

Believe me, I've gone through this before...and I still say it's a clocking issue with one of the pieces of gear you have hooked up. And it's not something you can easily fix right now, more than likely you recorded it with an incorrect clock setting. The Rosetta might have been set to 44.1kHz while Pro Tools was set to 48kHz and was trying to receive clocking information from the Rosetta.
Also, are you sure your session is set up at 48kHz? Press Ctrl (apple)+2 to see.

yousa, I knew there was a reason for me reading this thread (apart from trying to help the OP)

I've been mixing a compilation of tracks from a load of live recordings I did. One of the said sessions was (for some reason) recorded at 48. I didn't realise this untill it came to burning the disc. Suddenly I thought of BBS & this particular thread, I imported the mixes into another session applied a dither & badabip badaboom

thanx folks
