How to clean up Guitar hum
How to clean up Guitar hum
Hi, i use a direct recording with that setup:
Guitar > Tubeman 2 > audio card > Ableton > Waves GTR 3
I got a very good sound but even in the cleanest setting with no distortion i got a little background hum. I would like to have a superclean silence between notes in the quiet musical situations.
Do you know a way to clean it up? Maybe a professional solution , NOT a noise gate plugin which cut out the notes decay, thanks!

Re: How to clean up Guitar hum
are u using balanced cables? a Di Box?
have you tried a DC-offset Killer?
+ there are many plugins for that purpose

Re: How to clean up Guitar hum
yes, balanced cables and the Tubeman is a tube Di Box.
Never had an offset killer, would be nice to hear something about it from you, thanks.

Re: How to clean up Guitar hum
have a look at live`s utility or saturator! they both have a DC button, which is supposed to do that
Re: How to clean up Guitar hum
the lowest pitch in standard guitar tuning is about 77Hz so start by cutting everything below about 75Hz.

Re: How to clean up Guitar hum
How good quality/old is the tube in it? New good quality tubes can sort hum.
Then there's other general ideas too though such as move your guitar (i.e. pickups) further from the PC or anything with PSUs/Electromagnetic stuff in it. Standing up close to an amp with big transformers is a great way to make you guitar hum due to the big transformers in it.

Re: How to clean up Guitar hum
Sonic Foundry's Noise reduction plugin is what I have always used. Probably a Sony version now...
You take a small sampling of the noise itself and get the plugin to analyse it. Then you can apply across an entire recording. A lot of adjustment may be necessary to try and reduce as much noise as possible without affecting the recording itself, but I've found it to work really well.

@Piplodocus: i think it's more than 1 year old tube, so changing it would be a good idea. I record directly so i don't have an amp with big trasformers; however you made me think about my audio stuff transformers near to the pc... I will try to go far away from them...
@crumhorn: your eq advice is a good idea, i'll try it.
another cause of the hum could be a heavy eq setting in the GTR3 preset (even the cleanest one), 'cause i noticed that if i turn the vst off the noise is very very low. But maybe GTR3 increases an already existing guitar hum.

Re: How to clean up Guitar hum
i rec (bass) at a medium volume, say peeking at -3 then bring the track gain down til any hum is gone, then waves x-noise to taste
arrived at by trial and error, probably not the 'pro' way, but it works (getting out my umbrella and raincoat now)

Re: How to clean up Guitar hum
also, if you use a CRT, turn it off ( more like a 90's advice tho, not a lot of people using crt's nowdays)

Re: How to clean up Guitar hum
If you've nailed some recordings and the hum isn't causing you a problem where you're playing you could try gating the audio so that you get that silence you're after between notes.
Re: How to clean up Guitar hum
I tried to gate the audio but this is not working for clean guitar notes at low volume.
The hum is not so big, but would be nice to have a professionally clean recording.

hum is part of the ambient sound of the guitar, let it go.filter_7 wrote:The hum is not so big, but would be nice to have a professionally clean recording.
a gate should be enough, anything beyond that is part of the instrument.
yay humbuckers.

Re: How to clean up Guitar hum
Most times, the hum is actually at double the line frequency (so 100 or 120 Hz). A very steep notch filter at that freq can be used to reduce hum.crumhorn wrote:the lowest pitch in standard guitar tuning is about 77Hz so start by cutting everything below about 75Hz.
Use downward expansion rather than a noise gate to deal with hum at low volume levels.
But the best way to get rid of hum is at the source, make sure the guitar is properly shielded and grounded (guess what, out of the box very few are).
Re: How to clean up Guitar hum
@doghouse: ouch, i never thought about guitar grounding, i will check that.
One thing: how can i be sure about that without being 'expert'? Is there a kind of box that can measure the hum?
I have a Tubeman too, so i must check every ring of the gear chain.
