Live audio noise reduction hardware,
using an analogue strong pass audio filter, with adjustable setting of minimum pass level. Idea & solution by Joar Falstad.
The weakest parts of the total signal, smaller than the preset minimum
pass level, are redused by a factor.
Up to 100x or -20db reduction
is used in our filter .
The result is natural sound and the background noise is reduced to a minimum. This system will shave any audio signal below the preset minimum level all the time , also inside a message .
Fast analogue filter action.
No audio signal delay. Compared to the original signal
, tone balance and pitch are not changed in any way,
only the disturbing background noise has almost vanished.
