I have a technical question which I suspect has a straightforward answer that I
have somehow just not grasped...
Does anyone know of a way to batch process a number of vocalizations (some very
loud, some very soft) so that their maximum amplitudes are all the same, using
AviSoft software?
I have several 100 vocalizations that I want to analyze in AviSoft. As these
recordings were done under natural conditions -- I had varying distances
between the calling monkey and my microphone -- my spectrograms all have
different amplitudes.
I want to normalize all these spectrograms to have identical maximum
amplitudes. There is a "normalize" function under the Edit/Volume menu but I
can't seem to find the way to get all the different spectrograms to have the
same amplitude maxima. If I specify a certain % in the Normalize tab the
different calls still turn out to have very different maximum amplitudes.
I can adjust the individual spectrograms' amplitudes to a specific value by
multiplying/ dividing it with a different value for each spectrogram but this
forces me to determine that value for each call individually, and apply the
math to each spectrogram individually. I'm certain there has to be an easier
way.
Thanks so much for your help!
