different sample rates and bit depths

[Andres Gonzalez]

This is a basic question but I want to ask it anyway just to be sure.

I have been using PT HD for several months now but always at 44.1K sample rate. I now want to try some of the higher rates. I created a session at 88.2K sample rate, 24 bits. Then I imported a wav file that was 44.1K/16 bits. It works fine but I have a couple of questions.

I want to record some new tracks at 88.2K/24 bits in this session that has a wav track at 44.1K/16 bits. PT seems to handle tracks with different sample rates and bit depths but am I going to have any problems because of this?

I have been using Waves L2 on a Master track to mix down and dither back down to 16 bits. How do I down sample to 44.1K while I dither to 16 bits during mixdown?

Thanks,

-Andres

I'm pretty sure that the 44.1/16 file you imported was converted to 88.2/24 when you brought it into the new session. Unless I'm missing something, PT only works with one sample rate and bit depth per session. Even with 16 bit dithering, if you're rerecording into PT, it's still recording at 24 bit (I guess with 8 extra zeros per sample). I'm not sure how Bounce to Disk does it. Mixing down to 44.1/16 would be achieved by sample rate converting at some stage. (Bounce to Disk, Export, or 3rd party.)

If you import audio into a session that is at a different bit rate or sample rate, ProTools automatically converts the file to match the session.

Thank you for all of the responses and explaination. It makes alot more sense to me now.
