C: adds multiresolution operation for better handling of signal transients and even fewer musical noise artifacts.It is more CPU intensive and has more latency, but can still run in real-time on most machines. B: achieves more advanced musical noise suppression by using adaptive 2D smoothing (both time and frequency).It reduces musical noise artifacts by time smoothing of the signal spectrum. A: is the least CPU intensive process and is suitable for real-time operation.RX’s Spectral De-noise module offers four algorithms that vary in processing time. This selection directly affects CPU usage. QUALITY: Affects the quality and computational complexity of the noise reduction. Strong suppression of noise can also degrade low-level signals, so it is recommended to apply only as much suppression as needed for reducing the noise to levels where it becomes less objectionable. in some situations it can be desirable to reduce only unpleasant buzz while leaving unobjectionable constant hiss). You can specify the amount of suppression for these parts separately (e.g. Spectral De-noise can automatically separate noise into tonal parts (such as hum, buzz or interference) and random parts (such as hiss).REDUCTION (NOISY/TONAL): Controls the desired amount of noise suppression in decibels. If background noise changes in amplitude over time (like traffic noise or record surface noise), raise the Threshold to accommodate for the changes.Manually learned noise profiles are best suited to removing or reducing noise that is constant and continuous throughout the duation of the file. After a noise profile is captured using Learn, it remains fixed for the duration of processing.
LEARN: When Learn is enabled, Spectral De-noise will capture a noise profile from your selection. It also provides separate controls for tonal and broadband noise, management of denoising artifacts, and an editing interface for controlling reduction across the frequency spectrum. It is a flexible tool that can be used to quickly achieve accurate, high-quality noise reduction. Spectral De-noise learns a profile of the background noise, then subtracts that noise when a signal’s amplitude drops below the specified threshold. It can be useful for tape hiss, HVAC systems, outdoor environments, line noise, ground loops, camera motors, fans, wind, and complex buzz with many harmonics. Spectral De-noise is designed to remove stationary or slowly changing tonal noise and broadband hiss by learning a profile of the offending noise and then subtracting it from the signal. The new Spectral De-ess mode transparently attenuates sibilance with iZotope’s Spectral Shaping technology.Spectral De-noise Module & Plug-in Remove distracting mouth noise with the new low-latency Mouth De-click.
