| Algorithmix Easy NOVA Details
Denoising techniques work well for stationary or quasi-stationary broadband noise. Short clicks coming from old records or switching noise can be successfully removed and replaced by declicker plug-in. However, neither a denoiser nor a declicker can successfully cope with longer complex audio disturbances, especially if they overlap material we want to recover. This fact has motivated us to develop a special tool, reNOVAtor and later its brother, Easy NOVA, especially optimized for time-effective workflow.
Easy NOVA is intended to rescue high-resolution live or location recordings from extraneous sounds and unwanted audio disturbances. Often, from the performance point of view, brilliant live recordings can not be accepted for CD release, because of disturbing noises like coughs, squeaky chairs, feedback squeals, horn of a passing truck, a bell from the neighboring tower, or ring tones from a cellular phone. Such disturbances are especially critical if they occur in quiet passages when recording classical music. Similarly, location recordings film, broadcast or TV often include annoying incidents which disqualify them to be used as originally intended. In these cases any kind of traditional equalization or editing methods is very time consuming and causes audible discontinuities in desired signal and ambience. Often after hours of hard work even the best post-pro engineer will capitulate.
Easy NOVA helps when all other editing tricks and processing methods fail. It allows localization, identification and very precise removal of unwanted audio events mostly without audibly affecting the audio material we want to keep. The removed sound is replaced by a signal re-synthesized from the surrounding material. Unlike time editing methods, Easy NOVA does not make deep gaps in the sound track when eradicating a disturbing sound event. Rather, its an exactly tailored hole in the spectral representation of the processed signal that can be removed and replaced.
Algorithmix Easy NOVA Features
- flawless operation with up to 384 kHz sampling rate, thus perfectly suitable for DSD post-production including cleaning in the ultrasonic range

- audio fixes that were basically impossible until now
- enormous time saving in repairing critical live recordings
- easy-to-learn identification and localization of unwanted audio events
- well prepared preset-like controls for very time-effective workflow
- efficient removal of unwanted disturbances and their replacement by signals re-synthesized from the surrounding audio material
- all processing functions in linear-phase domain to prevent unwanted sound coloration
- no audible changes in desired signal and ambience after removal of typical discrete audio disturbances
- two different kinds of spectrum re-synthesis
- extended resolution for low frequencies
