Are there any advantages to collecting data at a sampling rate higher than a recording device can physically record?
As you know, the minimum sampling frequency is twice the highest frequency of interest. If you can afford, you could sample at least 3 times the highest frequency improving the signal waveform close ...

Are there any advantages to collecting data at a sampling rate higher than a recording device can physically record?
However, the highest frequency response that the device's microphone can collect is 16kHz.
This isn't really true, at least it's not true for typical microphones. The maximum rated frequency is the ...

Are there any advantages to collecting data at a sampling rate higher than a recording device can physically record?
Yes, as WMXZ has mentioned the Nyquist rate determines the maximum frequency that can be reproduced with fidelity, but I think that's only part of the story here.
If one wants to avoid aliasing, then ...

Recommandation to design a fish tank for acoustic experiments
IMO, a lot depends on the type of sound, and experiment you wanted to carry out.
I see two different issues:
resonance that can occur for lengthy tonal and tank linear dimensions of wavelength/2 (e.g:...

Anyone have experience using frequency trigger in AudioMoth?
Megan, Hi. The trigger option within Audiomoth firmware is quite new, so there are probably few people able to comment well on this?
However... the use of amplitude-based triggers within the audible ...
