Noise reduction for sounds coming from microphones
Hello everybody,
I am using a contact microphones (actually a couple of capsules with a circuit created for the purpose), but I get a very high noise when I get the sound of the mic inside a max patch.
Do you have any suggestion to reduce such a noise (withouth passing for fft)?
Are there some objects that implement hiss reduction and noise reduction?
Thanks in advance
Luca
Hi list, first time on this forum for me.
Luca, I think your problem comes from the microphones..contacts ones tend to increase noise drastically, especially if you're not using them for triggering purposes..also, if your sound source is not loud enough, you have to increase the gain a lot, doing so also with the noise.
I could be wrong, but I had the same problem with a yamaha DT 10..
I think the best solution is to fix first your 'hardware' problem..you won't need a noise or hiss reduction then.
Anyway, as I know, maybe some plug-in would meet your need, but I don't think there is any maxobject doing that (without passing through fft)

Hi Marco,
thanks a lot for answering. Of course the best solution should be to have better microphones, but at the moment I have to use the
microphones I have in hand.
So I need to reduce the background noise....of course it is amplified by the gain I put in the max patch because the signal in is too weak.
Any suggestion?
Thanks
Luca
Maybe you can try Xcrakle, Xhum, or Xnoise plug-in from waves.
Another solution would be to build in max (or again get the plug-in..)a gate with a noise-treshold, so the signal below the treshold (the noise) will not pass the gate.
If you're going to build it in max, you could gate the signal before, and then boost the 'clean' signal only (this is just an idea..I don't know if it's the best solution)
Hope it helps

Hi!
Thanks a lot for the suggestions.
I have already done what you suggest me. I have also implemented an external that taken the input signal, set the output to 0 if the amplitude level of the signal is less than a threshold.
The problem is that in both the cases some distorsion in the sound are introduced.
I think that a specific object for noise reduction is the best choice...
Does someone know any object that do this?
Cheers
Luca
