DeNoise – software hiss reduction
Hiss, and other mid- to high-frequency noise, can be reduced using the DeNoise application.
Hiss reduction – how it works
Suppose you had a 1024-band graphic equalizer, and that you could adjust all 1024 gain controls 80 times a second. Impossible? Quite possible! DeNoise operates as an intelligent graphic equalizer, dividing the incoming audio into 80 overlapping frames per second, automatically and continuously adjusting the gain of 1024* frequency bands. It uses algorithms that judge what will be perceived as noise, and what will be perceived as desirable audio, and applies a balancing act to suppress the noise without doing perceptible damage to the sound.
* 2048 bands if the sample rate exceeds 48kHz.
