It looks like we’ve lost the noise gate again. I remember that happening with 3.0.0 and then fixed in an update but it looks like it’s a bug once again. I tried it in both 3.2.0 and 3.2.1 on my MacBook Pro with an M1 Pro processor. No go.
Works for me on W10 with 3.2.1
It opens ok but applying the effect does nothing. This is what it did back in 3.0.0 too. I think it got fixed in 3.0.1 but it’s reared its ugly head again. At least for me on a Mac.
If the threshold on a noise-gate is set too low it will do nothing to the audio.
If the attack on a noise-gate is set too long it will do nothing to the audio.
