I am a researcher using Bela for generating auditory stimuli for mice. Mice hear far out to the ultrasonic range, and we would like to use frequencies on the order of 30-40 kHz. This necessitates at least doubling the existing 44.1 kHz audio output given Nyquist limitations. I saw several threads regarding changes to the sampling rate but the outcome seemed inconclusive; anyone have the latest on achieving 88.2 kHz with the audio out specifically?
The use case we have requires a mono output, so we can drop the second channel - no need for stereo. Indeed, my hope was/is to do exactly this, analogously to the way you can drop channels to increase the sampling rate on the analog outs.
If I understand correctly, one alternative is to buy the audio expander capelet and then per the supported manner, double the audio-out on the analog out that is now acting as an audio channel; I'd rather avoid this since it requires a dedicated amp etc.
So if anyone has any ideas on the best way to double the audio channel output frequency (I would be delighted to be told I am dumb and a thread already answers this!), it would be much appreciated.
