Hello,
I'm looking for a quality spectral gate. Something that allows me to attenuate lower volume sounds, but leave the others intact.
It's not a normal gate, because it affects only some (lower in amplitude sounds).
Any help would be very appreciated.
Thanks!

Umm..can't you use the threshold control on any normal get for the same effect? Or did you mean lower pitched sounds? Oh wait. You did mean pitch. Perhaps the combo of a filter and gate would do the trick.

Naah, this sounds like the job for an expander. It's the reverse of a compressor. Actually some nifty compressors can do expanding!
Now I wonder what the "spectral" thingy should do...

It's not an usual expander. Its based on spectrall componets, so the lower volume sounds are attenuated while the higer volume sounds with keep intact.
An normal expander will get all the mix attenuated.

That's a standard method for noise reduction, so you might try searching for noise reducers. I can't name any off the top of my head, though (that's the kind of thing I program myself whenever I need it).

spectral means the gate works based on frequency
normal gate does exactly what you described. the treshold determines the volume of the sound where the gate kicks in. have it lower and only lower volume sounds will be affected

For those still confused, a spectral gate mutes individual frequencies below the threshold.
Say you have a sound which consists of 100Hz at -0dB, 200Hz at -5dB, 300Hz at -15dB, 400Hz at -10dB, and 500Hz at -20dB.
If you use your spectral gate to gate everything below -12dB, then the 300Hz and 500 Hz components of the sound will disappear. Ideally of course. It depends on the quality of the analysis process.
This, as previously stated, is particularly useful for noise reduction (aside from odd sound design, of course
). All the tiny (we're talking really, really narrow) frequency bands where there's nothing significant (i.e. above a certain volume) going on are eliminated. Basically, since you can only hear low-level noise through the 'gaps' in the frequency spectrum which the music doesn't occupy (it's masked otherwise), completely silencing these gaps works pretty well as a psychoacoustic means of noise reduction.

Thanks all
I'm looking for real spectral gates. Avanced ones with many controls. I found Ionizer but can't put it sounding half good. http://www.arboretum.com/products/plugi ... er_dx.html
Spectral expanders would be cool too.

delaydots.com SpectrumWorx have excellent spectral gate thats for sure.

All the ones posted here are "real". And if you can't get good results with Ionizer, maybe something that works well for you is more important than something advanced.
