How do you get rid of the hissing? You know the stuff that just sits at the top end of a mix and the more you hear it the worse it gets…
Ive got good cables, nice pre-amp but just cant seem to get rid of the noise… everything Is sent to unit gain… any suggestions? No-body else’s music seems to have the same amount of noise as mines does, it’s actually bizzare! helppp!
please:roll_eyes:
Whats your signal flow? Knowing what gear you’ve got might help find a solution.
Modular, 12MTK, P6, Strymon timeline, Eventide space, ISA pre-amp.
Desk, p6, modular, pre-amp and adam a3x’s are being powered by samson power strip. Pedals are powered by a Lindy isolated power conditioner.
It really seems to be when Im using the prophet 6 tbh… I know it’s unbalanced outputs but did not for one second expect it to be this noisy. It normally gets to the point where I have to roll off pretty much all of the high end on the desks EQ which is never good if Im wanting that high pass sound…
Using overdrive? Overcompressing? Try recording the prophet louder so it’s peaks are higher than its noise floor?
Nah I never really overdrive and rarely stick my p6 through the compressor. The only way I can really get the prophet to cover the noise is when theres alot of bass frequencies (which is far too much ) kicking about. Later on it has to be filtered and then bam the noise is back…
Even still with all this bass going on it still sits at the top end of my mix every time…
Hmmmm Got any examples?
I could certianly find one! Bear with me.
Hmmm, do you have both powerstrips plugged into the same outlet? If not you could be introducing some ground hum.
Yeah, ive no other choice in the matter, believe it or not I have only 1 outlet in my room. It’s not hum that im experiencing or is that a technical term? 
In my experience ground noise is definitely noticeable vs line noise. Can you get the noise with no synths sounding off?
Yeah the noise is there when no synths are active and just the faders are up at unit gain. But more so with P6 and less so with modular and other stuff.
Sooo if it becomes impossible to eliminate but it’s around even when the synth isn’t playing. What you could do is borrow a technique from long exposure photography. And record what’s callled a “black” frame. In photos the sensor heats up the longer you leave it exposing. This raises the visual noise floor. If you’ve take a cellphone pick in the dark you know what this is. What some cameras do is fire the sensor for a equal amount of time after the initial exposure without firing the shutter so it’s just a black frame with the senseor noise. Then it uses that frame to remove the noise from th initial photo. The same could be done here by recording your rig with no synths playing after the jam and using that as a “black frame” phase invert it and it should do basic noise cancellation on the line noise frequencies.
It’s kind of in essence how balanced outputs work but it’d not be in real time. Could work though.
Not gonna lie man, im confused as 
…
Well first. Try and adjust your gain staging. Max your synths where possible and use as little preamp gain as possible. This should get you the cleanest unity gain.
If that doesn’t get rid of all the noise. Record your song. If it’s say, five minutes. Record ANOTHER five minutes of the rig but with no notes playing, JUST THE NOISE as an overdub.
In your daw. Phase invert the noise only track it should clash with the line noise in your synth recordings and lower the perceived. Noise level.
Phase cancelllaton is what happens when you have one signal at say +5 and another signal at the same time reading -5. 5-5=0 so the Percived amplitude to your ear would be 0 it’s not gone it’s just kinda masked away.
Recording noise like this means your generating as close to the same random signal as possible and when you flip it’s phase you’re sending - values to the original recordings + values. But only for the noise.
Nice man. Really appreciate this. Can always rely on this forum for a solid answer. Im going to give it a bash.
Just out of curiosity, where did you get your knowledge?
Also, lets say ive highpassed all my low end and wanting to get it loud enough to be audible again, whats the best way to boost without bringing up the noise again?
I’m just a dork who reads a lot and spends way too much time on YouTube learning how things work 
not sure how to help as far as the high pass question goes. Usually best practice is to try and scoop unneeded frequencies from your other instruments if you want something to cut through. Hard to tell without working on a specific project. Million ways to skin a cat and all that.
Yah man, I feel ya! Nothing wrong with being a dork if you’ve got the answers. Cool well thanks anyway man. Im going to try work on my gain staging. It’s strange for me to get my head around it. Anywhere youd reccomend to learn valuable info?
Sound on sound has a ton of old articles on their site that covers every topic imaginable
Phase cancellation doesn’t really work like this if it’s true, random noise. The noise floor won’t be the same exact pattern of noise, so it’ll just stack and the noise will be louder. It’d work if you had a persistent hum in the background of your recordings though, as long as you got the phase right.
I use Klevgrand’s super useful Brusfri plugin, it’s very good especially in my setup where I have a lot of old handheld game consoles with loud noise floors! It works in a similar way to your theory—you “prime” it with the noise floor you want to eliminate, but I think it uses FFT to remove the noise instead of phase cancellation.
