I asked the following question in the Polyphone forum
(http://www.polyphone-soundfonts.com/en/forum/soundfonts-help/29-understanding-attenuation)
but didn’t get a conclusive answer.
I've created presets in Polyphone using a sine wave
sample with 72 dB, 48 dB, and 0 dB attenuation, then rendered a
1-s tone of each (at velocity 127) with Fluidsynth, then put the
wav files through Audacity's spectrum analyzer.
The difference in the peaks is only about half as much as the
numbers provided to Polyphone, and I don't understand why. Is
this a suitable way to verify the effect of the attenuation
parameter?
Thanks.
