Use the intuitive display of the Oxford DeBuzzer from Sonnox to help isolate the fundamental frequency—constantly giving you feedback on the top contenders—or define the frequency manually with the help of a tone generator. Don’t worry if the fundamental wanders, the default Auto Tracking Mode will follow it in real time. The harmonics of your problem fundamental frequency will also be tracked. All that remains is to engage the default comb filter or the optional parametric EQ, and then fine-tune the content that’s removed using Diff auditioning. It is provided as AAX, AU, and VST3 plug-ins and works with macOS and Windows.
