My Amadeus Pro sonogram preset
When I do audio editing in Amadeus Pro, I find its Sonogram command useful. That command gives me a three-dimensional graph of frequency distribution through time:
The default setting shows the z axis with a color gradient of white through orange through blue to cyan, which I found hard to read. What you see above is my variation on the built-in “Greyscales” preset: Just like a printout, white is dead, black is maxed.
The difference with my preset is that the original is linear, whereas mine is a curve. Here’s the preset editor, showing my preset:
Sampling the swatches in that screenshot will tell you that the five equally-spaced gradient stops are:
- White
- 50% gray
- 25% gray (at the halfway point)
- 12.5% gray
- Black
I’ve found that these settings make the spectrogram clearly readable without my having to fiddle with the “range” and “gain” sliders.
