Noise Gate for Windows

Noise reduction using spectral subtraction.

This is a noise gate VST plugin — software for audio noise reduction ("cancellation") before or after applying other effects that may highly amplify noise like a distortion, compressor (sustainer, limiter) or a guitar amplifier at high gain. The plugin can also make noise reduction on a whole phonogram with some conditions. But the main purpose is to cancel noise from a microphone or pickup of a music instrument like guitar before sound processing rest. The plugin has good enough characteristic at signal release.

There no common highly effective technique for canceling any existing type of sound trash so far. Clear interface of the 7AMP Noise Gate with just a knob and just a button allows to understand quickly if the plugin is able to implement reduction of your particular stray signal, saving your time. You simple hold your strings for a second, or keep your microphone in silence, allowing the plugin to study noise pattern, then you set filtering level. Works? Fine. Doesn't? Try another noise reduction plugin.

Inside the 7AMP Noise Gate there are 7 fast fourier transform elements applied to 512 samples length audio blocks to implement standard (almost) spectral subtraction with all advantages and drawbacks of this method.

Guitarist/vocalist/another live artist (while recording and working at PC), sound engeneer.
