Hey! So there's a little thing I've noticed a couple of times now when mastering my tracks. After I'm starting to feel finished and have boosted up the volume, there's some sort of noise in the background that you can hear in the most quiet parts of the track if you crank up the volume in your speakers a bit. The reason I noticed it is because I usually have a bar or two at the end of the track where there is complete silence, but it's not actually silence because of this noise. Why does this occur and what can I do about it? Is it something I'm doing wrong when mixing, or does this happen to everyone?

I don't know if it's worth mentioning but I'm using ableton live.

Alright so I started working on a remix for Artifact's remix competition and would appreciate some feedback from you guys! Haven't put down too much time with mixing so you don't have to state any obvious mixing errors or so. I'm also new to deep and tech house so any tips from the tech-heads would be awesome!
