Ah, I see. Hmm, I want to try that with my cards as well. How do I have
to interpret the signal I've recorded?
Record silence and then comprare the highest peaks of noise level
to full scale and express the result in dB scale?
Example: If I get a peak-to-peak noiselevel of 6, is that -80 dB?
Or do I have to calculate RMS of the noiselevel first?
