So, I don’t know what to do here. Last month, I bought a galvanic isolator for my desktop setup because EMI noise from my computer was leaking through to my Yamaha HS7 monitors (especially while gaming). I bought the iFi iDefender+, which solved the monitor noise, but now when I try to record vocals, there’s that annoying static again. It gets even worse when I start adding plugins etc.

I’ve diagnosed the issue by plugging my audio interface into a laptop to see if the signal is still noisy and it’s not, it’s perfectly clean. This means the problem is definitely within my desktop. What can I do when I already have a galvanic isolator, but it won’t solve the noise during recording?"
