Mid/Side mode to optimise the denoising of stereo FM broadcasts.Graph to draw in the amount of noise reduction against frequency, creating high quality results by applying noise reduction only where it is really needed.Fast adapting Automatic mode allows quick results, even when background noise is continuously changing over time."Manual", "Noise Fingerprint Capture" and "Automatic" modes.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. By default the plug-in assumes Auto mode, continuously hunting either side of the nominal frequency for a peak profile.
The DeBuzzer has three modes, Fast, Auto and Freeze. In the same way as you can tune a guitar, as you home into the fundamental, the beat frequency between the tone and the fundamental will become slower and slower the closer you get. The third method of isolating the fundamental frequency is a tone generator. It will automatically mark the three highest peaks found, and you can set the nominal frequency by clicking one of the peaks on the graph. Second is the large FFT display which accentuates any frequency components that are consistently present, making them stand out in the plot.
The DeBuzzer has several ways of helping isolate the fundamental frequency.įirst is the Peak Profile that is displayed above the central rotary control, which shows the strength of a given nominal frequency in the input signal. For this process to work well, the fundamental frequency must be very accurately determined. The comb filter has many tight notches that eliminate the fundamental frequency and associated harmonics of the buzz. The Sonnox Oxford DeBuzzer is divided into two stages: Detection and Removal.īuzz removal is usually accomplished using a comb filter.
