I just finished my first track in Bitwig, and when I did the final export I was surprised to discover that my sample rate options were limited to just 44.1khz and 48khz. I like to work at a moderate sample rate and perform the final export at a high sample rate, typically 192khz, so this was disappointing to see.
Although I have searched I can't find reference to anybody else running into this limitation, so maybe there's something I am missing, my system is misconfigured etc.
I also attempted to change the audio engine to a high sample rate, thinking maybe the export-time engine is tied to the configuration of the real-time engine, but even when the engine is configured with a 192khz sample rate I only see 48/44.1 options during export.
Does this sound familiar to anybody else? Is there something I can do to make high sample rate export options available?
Windows 10/11, Bitwig 5.1.

Well as soon as I wrote that out and submitted it I realized something I might have overlooked:
The sample rate options I see when I export are "Current", "44100 hz", and "48000 hz". Wanting to explicitly choose the sample rate I ignored "Current".
"Current" _does_ use the sample rate configured for the real-time engine, so if I change the global audio engine settings to e.g. 96khz, then export with "Current", I get a 96khz file.
So mystery solved. This is workable for me, though I would prefer that the export settings are separate from the global settings so I don't have to mess with them during export (e.g. reconfiguring how Bitwig connects to audio drivers pretty regularly causes unexpected errors, lockups, crashes, etc.).

Hi,
I had a similar limitation on MacOS. How I worked around it is that I created a virtual audio device using BlackHole, which I then routed to the output. This virtual device I could put up to 192Khz.
There is probably a way to set up a similar virtual device in Windows. Then your current samplerate is also that 192Khz or higher, and using this trick I can export at 192Khz.
There is an extra benefit to exporting to a higher samplerate and then using a specialised program to downsample if necessary, even if you only want to export 44Khz in the end. It allows turning off some upsampling in plugins, which first upsample, then downsample. Upsampling and downsampling involves filters, and if you do it a lot in a chain, it becomes audible. Having the whole basis samplerate be higher, you can avoid the whole issue.
Of course, test by ear in the end
Best, Christian
