Fast Spectral Density is not normalized:
The MathCHOP that normalizes for FSD uses 1-1000 as a criterion whereas in the previous tox versions it was 100-1800
tox save build 2022.22260
version 6.0.2
Sorry, we changed the range to 0 to 1000 in December 2021 as the previous defaults weren’t meaningful enough, like when the input is 0. However the Slow Spectral Density wasn’t changed and the math may be approximate. We will look further into it. Thanks for pointing that out.
