.wav file exported on Mac won't play on Windows

I’m delivering stems for a film and the .wav files play fine on all my machines (Macs, iPads, iPhones) but won’t open on the film editor’s windows machine or his colleague’s windows machine. I’m on Cubase 13.0.30 and MAC OS Ventura 13.2.1. I’ve seen other threads with .wav issues where people talk about format of the drive being the issue? Cubase is installed on an APFS drive and the files are stored locally and in iCloud. They were delivered using file transfer.

Any ideas on how to fix this one?

Hi Stuart and welcome to the forum!

What export settings did you use? Specifically this section.

Would you be able to make a test export that you can share for testing purposes?

Thx for helping - here is a screen shot. I have a test export but not sure how I can share on here as file type not supported and links not allowed

its 64 bit float isn’t it… :slight_smile:

24bit is enough for an export.

Btw, your file system is encrypted.
Maybe the OS is protecting the files?

Well I went for highest quality extract for production quality. Won’t make that mistake again

I agree with @st10ss, sounds excessive. 44.1kHz is also an uncommon sample rate for film.
Are those the specs the recipient of your stems asked for?

To be on the safe side, always export audio 24/48kHz or 24/96kHz for film. These were the guide lines for given me many years ago.

If you want to keep your files in the floating point format (rather than going integer) 32bit float should do the trick. My cheap consumer level soundchip from Realtek can play back those.

Right, 24 bit /48 kHz and 24 bit /96 kHz are the universal formats for this situation for almost every film and similar media project I’ve worked on for years. Also, it’s ALWAYS good practice to confirm film formats/specs with producers beforehand anyway, just in case.
