Best way to do this?

I have some stereo mixes on a stand-alone hard disk recording unit (the old Akai DR-4D). It has SPDIF and AES/EBU outputs. I need to somehow wind up with a stereo interleaved AIFF file on my G4.

What's the best way to get there, maintaining the integrity of the files as much as possible?

My first (and obvious) thought was to take the SPDIF outputs of the stand-alone unit into ProTools SPDIF inputs and record into a new session. But the problem with that is that it creates two mono files. I would then have to "bounce to disk" to create a stereo interleaved file, and I'm constantly reading people talking about how "bounce to disk" degrades the sound quality.

What should I do?

Hmm..

I am unclear on this.. I use a Masterlink to make a CDR..

Doesn't Jam 2.6 handle split stereo PT files??

Anyone?

BTD may be your only option...

BTW it is not clear yet how but it is rumored to have been improved lately.. It's 'difference' to a mix recorded to another digital device is deeply engrained in PT user folklore... I amyself have never stopped to see the diffeence.. I wouldn't let it hold you back... Do a BTD now (use 'best' not tweekhead') & see if someone turns up with better advice...

Hi,

Just surfing through and saw the topic and reply.
I know this isn't addressing the original post but...
Someone tell me about BTD and the degredation that it creates in audio quality???

To answer the poster, I would have suggested what he already thought of but did not know of this BTD problem.

What version of PT are you using ... I suppose one that doesn't handle stereo files yet right ???? If not you could just record stereo files in Pro Tools.

anyhow ... you want those old mixes on your HD to burn them to a CD using Jam or Toast or a program like that right ???

You do not necesseraly HAVE to bounce those files if you record them as 2 monofiles in ProTools. what you can try is create 2 mono tracks in PT and name them carefully with a .L and .R extention.

Jam and Toast and I suppose maybe other burning softs will recognise the .L / .R files (for example mix.L / mix.R) and burn them as one stereo track. It works both in SDII and wave format .... no need to bounce them again before burning.

Hope this helps ..... describe your setup / PT version soft and hardware / and what exactly it is you want to do with the files after they end up on your HD if you have more questions.


cheers


oh ... and allways keep an eye on the clock issue when doing digital tranfers ... especially with formats like spdif and optical ..... unless you use a masterclock you should make absolutely sure that the ProTools slaves to the akai when doing the digital transfer

Hello Chris,

Interesting.

I think I have the latest version of PT: 5.3. I'm not aware that it records stereo files, I thought it only recorded dual mono files.

Yes, I'm trying to burn the files onto a CD-R, but I only have ITunes for CD burning.

I was also under the impression that there wouldn't be loss transferring via SPDIF. Is AES/EBU any better?

Thanks for the tip about the slaving, I'll see if I can figure that out.

you are right of course .... Pro Tools does not "record" stereo files as one file .... it splits them in two mono files ... but with stereo tracks it automatically adds the .L/.R extentions to the file names.

I would go for aes if you can ... it is a balanced transfer and you are less likely to have clock problems when using aes.

try this : create a new session 16 bit / wav format .... stereo trck .... record the mix through aes into PT

after that trim the regions so you have the audio beginning right at the beginning of the region and stop at the end.

then select the regions and go to export selected as files from the audio regions menu .... in here you can set some options like aiff stereo interleaved. you're allready in 16 bit so no additional conversion other then the file format needs to be done

you need aiff because itunes doesn't support split stereo files I think.

I wouldn't think that there would be any 'loss' in the files but I'm not 100% sure so ....

that's about the closest and best way I can think of getting to aiff single stereo files using your PT setup.

On the other hand I would strongle recommend trying Jam or Toast as they do support split stereo files in SDII and wav ... so you save yourself a lot of hassle. just record them to a stereo track at 16 bit and write those split stereo files as stereo tracks to the CDR.

let us know how you end up doing it

Thank you Chris. That's good info to have.

Someone on Nika's board mentioned there's also other software like Bias Peak that will record directly to interleaved stereo, which I wouldn't have thought of. That would probably be the way to go, it seems. Apparently you can download a free fully functional demo that works for 30 days.

But I think what I'm going to do for now is take Jules' approach and just borrow a Masterlink from a friend and make a CD-R. Hopefully there's not too much loss in that transfer to the Masterlink! Or in the burning of the CD!

There will be no loss any way you transfer digitally - and once you get it into PT you export as files, not bounce to disc, to get stereo. BTD is only for mixing and processing plugins. That is basic information! Bouncing can give you stereo files, but export as is more direct.

Lots of mis and incomlete information in this thread.

But digital to Masterlink will give you either or both aiff stereo and redbook CDRs, so you are on the right track. Recording to Peak is also very good way.

No substitute for years of experience, trying it different ways, and getting good advice from people who have done all that...
