CEDAR CS7: Debuzz
A plug-in to eliminate buzzes and hum, ideal for professional audio and forensic use
Buzzes and hums can creep into the highest quality recordings and live audio, but can be eliminated quickly and easily using Debuzz. This powerful but simple process removes unwanted signal components across the entire audio spectrum, and is capable of removing all manner of buzzes and hums with fundamentals as high as 500Hz.
Debuzz will also track wandering tones and, unlike traditional filters, can successfully restore your audio without unwanted side-effects such as limited bandwidth or the hollow sound introduced by comb filters.
