Triggering on sound pressure level peak (dBa) in frequency domain

Hello,

I can't seem to figure out how to trigger my recordings on sound pressure levels (dB(A)) in the frequency domain.

For example I would like to store sound recordings when there is a peak of 80 dB(A) between 4 and 14 kHz.

What is the best way to do this? The triggering function offers triggering on fft but the sound pressure level option is only available in the monitoring part of the system, not among the triggering alternatives.

Hi,

in the attachment is an example, how it is possible to trigger the values from the FFT using the vector reference curve.


If you experience any problems, we can also make an example on your setup file.
