That documentation is fascinating
@My name is mud . It seems to describe a gate + dynamic filter combined approach. I attempted to approximate this concept with a quick-and-dirty preset.
In this clip there are three sounds:
- Neither noise reduction technique - just an unadulterated Strat tone. Not very usable.
- Just the gate - even though the gate was dialed in very roughly, it does its normal nice job of chopping out noise between notes. However, during the final note decay, the gate obviously remains open and the noise essentially ruins the clip.
- The gate and a dynamic EQ. This Parametric EQ is controlled by an envelope follower such that it is basically flat when the guitar is loud, but the treble turns down as the guitar gets quieter.
I made a video even though I'm terrible at videos because it's fun to watch the EQ going bonkers while the guitar plays:
...Yeah, yeah, I know, leave the videos to Cooper. But still, for a rough hack, it's not terribly bad, eh? I think what would be better is this: Instead of just following the overall signal envelope at Input 1, if you could slice out a high-mid frequency range of the signal, and then use the volume of THAT to control the EQ. Then you would be saying "if the guitar is playing high mids loudly, leave it alone. If the guitar is NOT playing high mids loudly, start to EQ out the high mids." You could do even better by using a more refined EQ shape that really hones in on the buzz. Maybe you could use the tone match tech to tell the Axe "here's what the buzz sounds like by itself" and then the Axe could use
that to dynamically shape the sound, or something...?
Greater minds than mine have explored this in vastly more depth, but perhaps this hints at what might be possible using tech that already ~exists in the Axe code.
