Fast and effective removal of buzz, hum, whine and whistles. Use the intuitive display to help isolate the fundamental frequency – it’ll constantly give you feedback on the top contenders – or define it 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.
- Ultra high resolution detection and removal of unwanted buzz, hum, whine and whistles
- Separate Detect and Remove Sections for intuitive workflow
- Very accurate setting of fundamental over 3 frequency ranges
- Tracking Mode to follow fundamental and its harmonics
- Comb filter for tight removal over many harmonics
- Parametric EQ for more musical removal over fewer harmonics
- Audition removed buzz for confident fine-tuning
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.
In Auto Mode the nominal frequency is set with the large central rotary to within about 5Hz of a 50Hz or 60Hz hum frequency, the plug-in will automatically move towards the detected frequency And set itself up to remove it. Once the hum has disappeared, Freeze mode can be selected to set the nominal to this exact frequency and stop the detector from hunting. The large central rotary control can be setup to control three frequency ranges, determined by the LF, MF and HF buttons, and can be set with a very fine resolution of 1/10,000Hz. For removing whines and whistles it is best to set Freeze Mode, and then use the FFT to find the frequency of the whines. These show up as peaks on the plot, and then you can click on a peak to set up the plug-in to remove that frequency.
