I want to know the working principle of DeNoise

Question

Hello. I am an audio semiconductor developer who uses adobe audition in Korea.

I am using version 13.0.2.35 of Adobe Audition.

I am trying to remove Idle noise by using DeNoise to tune the sound source, but I need to know exactly how the sound is removed.

(Effects -> Noise Reduction / Restoration -> DeNoise)

For example, I would like to know the principle such as removing the input gain according to the Amount value. And if DeNoise remove the noise component, I am curious how to separate the noise from the original signal.

The homepage only mentions how to use DeNoise, and I have not been able to confirm how it works.

Thanks,

Gyuhwa

Sorry, we can't tell you - that specific information (and indeed all internal working information) is commercially sensitive and not made public. But all noise reduction works on the same statistically-based principles, and there are plenty of papers around that outline this - some in considerable detail. For instance - Statistical-Based Approaches for Noise Removal

But that's as much help as we are able to give you.
