for mastering, it would be really helpful to see how frequencies in different tracks add up. For example mixing bass guitar with kick drum, it’s easy for levels to become unnecessarily high, and seeing them stacked in an analysis could really help mastering.
I think the best way to deal with this would be a spectrum analyzer which can show the analysis broken down by track, stacked.
It would be great for renoise to support something like this. any thoughts? I know of a VST that can do something similar, but it doesn’t stack the signals so it’s still not ideal imo.
I think it would be smarter to use external spectrum analyser suite. I personally would vote for the internal spectrum analyser to be replaced with a spectogram with user controlled transformation size.
