Well, yeah, because that's the Nyquist limit at that sample rate. The max frequency needs to be below that (22.999kHz would not be undersampled). Of course, all of these frequencies are in the ultrasound range anyway.
Reducing the sample rate could cause aliasing. Oversampling shouldn't.
- klaff 9mo ago22 kHz is not a hard/fast limit. There are people who can hear a bit above 20 kHz. I learned this when working with motor drives (at 23 kHz) but also documented in this wiki reference. https://en.wikipedia.org/wiki/Hearing_range#cite_note-10 https://en.wikipedia.org/wiki/Hearing_range#cite_note-10
