Understanding the effect of the Whitening control If you need to cut very high, inaudible frequencies, set this to 0.The position of the slider controls the influence of psychoacoustic model on suppression levels. This potentially reduces the amount of processing done to the signal and may positively affect overall signal integrity. When noise in certain regions is calculated to be inaudible, this feature prevents any signal processing in these regions. Masking enables a psychoacoustic model that dynamically controls suppression amount to facilitate the use of softer suppression where noise is subjectively inaudible.MASKING: Reduces the depth of noise reduction where you wouldn’t perceive any effect from it.Enhancement can make the resulting signal brighter and more natural sounding, but high values of harmonic enhancement can also result in high-frequency noise being modulated by the signal.This aids in preserving high-frequency signal harmonics that may be buried and not detected otherwise. Enhancement predicts a signal’s harmonic structure and places less noise reduction in areas where possible signal harmonics could be buried in noise. ![]() ENHANCEMENT: Enhances signal harmonics that fall below the noise floor.Too much Synthesis may cause apparent distortion in the signal. Increasing Synthesis can increase the sense of life and air in processed audio.The synthesized harmonics remain at the level of the noise floor, and serve to fill in gaps in high frequencies caused by processing. When Synthesis is set to a value greater than zero, signal harmonics are synthesized after denoising.SYNTHESIS: Synthesizes high frequency material after denoising.However, when using FFT-based processing, the more audio you remove from your source, the more likely you are to create undesirable artifacts. The greater the FFT size, the greater the frequency resolution, i.e., notes and tonal events will be clearer at larger sizes. ![]()
