When I try to export a 5.1 PCM wave file I'm getting an error saying the file has exceeded the maximum size allowed for the selected format.
It has been years since I've had to export 5.1 audio, but I seem to remember in Vegas Pro 18 or 15 that there was a 64 bit wave format (*.W64 Sound Forge file or something) that could handle a larger file size. However, I can't find that option in Vegas Pro 23. Was it renamed or moved somewhere out of the ordinary? Is there a more modern format?
What is the official workflow these days for 5.1 audio?
