NOTE: For macOS 10.6.8 -> macOS Mojave. Not compatible with macOS Catalina. The Spectral Repair Tool™ option for soundBlade allows visual localization, identification and very precise removal of unwanted audio events without affecting the audio material you want to keep. The removed sound is replaced by a signal re-synthesized from the surrounding material. Spectral Repair Tool For soundBlade does not make deep gaps in your sound track when eradicating a disturbing sound event. Rather, it’s an exactly tailored hole in the spectral representation of the processed signal that can be removed and replaced.
