Record in 443HZ, but end up with 440HZ Wav Files?

[lokotus]

Hi folks,

the title says it all.
I have a wav file playback in 440 HZ but the musician wants to be recorded in 443 HZ.
I have heard that you can somehow change the playback speed in Pro Tools, so the musician can hear the playback in 443 HZ and record in his comfortable tuning but the final WAV File result will be 440 HZ when played back at original speed. .
Can anyone guide me through the settings about how to achieve this in Pro Tools for me to get a better understanding.

Thanks a lot,
lokotus

Hi, welcome to the community.

Musician just tunes the instrument by 443Hz, not 440Hz. It has nothing to do with sampling rate. If you need to re-pitch pre-recorded audio you need to process the files (443-440)/440*100=0.68% higher

Yes. You can do this. We do this in countries that have different tunings (or, tunings specific to materials.) The usual way is to use varispeed on the clocking on an HDX system. You set the word clock for the system faster during the record process and then put it back to standard rates (44.1k, 48k, whatever) after and it'll playback at the correct 440Hz tuning.
Not all hardware can do this!
The MTRX units can't do varispeed (Dante will not do varispeed.)
The HD IO can, the HD MADI can only when set to 56ch/48kHz, other third-party hardware can (like some of Antelope's which is used at Synchron Stage regularly in varispeed)

The SyncX and SyncHD (and there are other master clocks) can be used to set the varispeed. (but once again, not all master word clocks can do varispeed.) You need both (audio interface and master word clock) to be able to do varispeed in order to do this.

There are some CoreAudio/non-HDX hardware interfaces that can do varispeed but I don't know if Pro Tools will complain if they are at non-standard sample rates. The usual way (the only way I've done this) is with HDX hardware.

RME in the past have said CoreAudio does not play well with Varispeed, ASIO can but I think there may be other issues doing this with their USB interfaces. I remember asking and looking at their forum and my head hurt too much to want to go further.

You can use Elastic Pitch to change any existing 440 audio by pushing it +3 cents.

The OP's post had me curious about 443HZ tuning and I found an informative article on iZotope's website.

A little excerpt:

"For example, The New York Philharmonic uses 442 Hz, the Boston Symphony Orchestra uses 441 Hz, and many symphonies in parts of Europe use 443 Hz or 444 Hz."

440 to 443 isn't 3 cents, more like 12 cents.

As BScout says, the right way to do this is with a system that allows VSO. If you can't do that and it's only one instrument that's at 443, I'd make a ref mix of the other tracks, pitch it up 12 cents with some utility like Pitch 'n Time/SoundShifter/Elastique, record the 443 instrument to that, then pitch it back down to marry with the rest of the tracks. If it's mostly 443 instruments, then I'd just pitch up the other instruments to match and go with that. Much less ideal than the VSO scenario, but workable.

Thanks for the correction

thank you very much for the detailled answers - a lot to learn here

That there is Almost 20 years here and still learning stuff. In any case, Pro Tools won't change the pitch of anything unless you tell it to. If it records an instrument that is tuned to 443, it will play back at the exact pitch it was recorded at. Now with VI's(virtual instrument plugins), that's probably a different story. Some may have the ability to alter the tuning within the plugin. For those that do not allow this, you could commit the track(which creates an audio file) and re-pitch that audio file to match any tuning you need.
