Sonnox Restore is a suite of three plug-ins - Oxford DeClicker, Oxford DeBuzzer and Oxford DeNoiser - designed to accurately restore audio recordings that are impaired. Restore represents a quantum leap beyond previous restoration plug-in technology with its advanced algorithms and novel features that allow fast and extremely effective removal of pops, clicks, crackles, scratches, hum, buzzes and extraneous background noise from virtually any recording.

Capable of exceptionally high quality audio repairs, the three plug-ins are intuitive and easy to use, with each interface providing detailed graphical feedback, benefiting the user by saving time which of course is critical in the post-production process.

Oxford DeClicker
The Oxford DeClicker has three main sections: DePop, DeClick and DeCrackle. These three sections deal with events that are up to 10ms, 3ms and 0.4ms in duration, respectively. Each of these sections has a threshold and sensitivity control, and an excitation profile which shows the residual signal left after harmonic content is removed. The excitation profile represents how much the signal deviates from the predicted signal.

Oxford DeBuzzer
The DeBuzzer has three modes, Fast, Auto and Freeze. By default the plug-in assumes Auto mode, continuously hunting either side of the nominal frequency for a peak profile. Once the lock strength rises to be above a certain level, the plug-in automatically sets the nominal frequency to the frequency of the peak found. If the hum is wandering in frequency, the detector will follow. Auto Mode is suitable for tracking a weak, slowly wandering fundamental and operates over all three frequency bands. Fast tracking mode allows the removal filters to automatically follow a quickly wandering fundamental.

Oxford DeNoiser
The Oxford DeNoiser removes wide-band noise from audio material using a variety of sophisticated techniques. The key to good de-noising lies in helping the user produce pleasing and accurate results, rather than encouraging the over-aggressive use of controls. The Oxford DeNoiser is based around the concept of a 'noise profile'. The noise profile is used to gate-out components of the frequency spectrum that are below it, and keep the components that are above it. There are several methods to arrive at an appropriate noise floor.



NOTE: Sonnox plug-ins require a 2nd Generation iLok for authorization.
