My deployment times and recording durations are both modest, which mean that storage and battery life aren't an issue. If I want to record calls in the 2-8 kHz range, will I get the best results by setting the sample rate to 16 (the Nyquist rate for my target) or setting it much higher (for example the default of 48) and then filtering the recording in post?

If you want a better signal-to-noise ratio, lower the sample rate. This holds true whether you record at a slower rate on the device or apply filters and downsamples after the fact. basketball legends
