Probably a stupid question, but does there exist a plugin or tool that can remove (or diminish) wah pedal effects from an isolated guitar track? (lemmy.world)

I transcribe music, and I sometimes come into possession of original instrument stems for the music I'm transcribing. Even with the isolated guitar track, the wah effect can sometimes make it difficult to hear what's actually going on (I'm talking mainly about very fast/chaotic metal music where the guitarist is flapping the wah pedal like a tasered duck's beak). I believe that if I could solidify the tone by removing the timbre-shifting effect of a wah pedal, it would work wonders for the audibility of individual notes.

Obviously I don't need the plugin or tool to preserve the original studio quality of the audio or to make it sound convincingly de-wahed to a casual listener, it's purely for making the audio more uniform and easier to "read".

Do such dark arts exist?

Cheers!

We’d treat it as a transcription aid rather than trying to reconstruct the original tone. A wah creates a moving resonant peak, so perfect removal is unlikely, but a spectrogram can help track note fundamentals while the passage is slowed without changing pitch. Then compare candidate notes with the surrounding harmony and use narrow, automated reduction only where the sweep masks the attack. Keeping the untouched stem alongside the processed version helps preserve timing and note starts.
