This hypothetical “spectrum follower” feature could be applied in a similar fashion to noise reduction: in 2 steps …
-
Highlight a section of one track, then press a button, lets call it “save spectrum”.
-
Highlight another section, (typically on another track), then press an “apply saved spectrum” button and that portion of the second track is equalised so its spectrum matches the first sample.
Personally I’d be prepared to copy and paste the spectrum.txt data into nyquist code, like this
but the method I have described above would be more widely acceptable.
I’m not sure that the (limited ?) demand for such a feature would justify the effort required to create it.
