Real-time Automatic Equalization for Reducing Spectral Masking in Problematic Frequency Bands between Vocal and Instrument Tracks

 

Audio plug-in software development in

C++ / JUCE / Faust

 

The analyzer graphics shows

1) Frequency spectrum of each signal

2) Problematic frequency bands indicated red color

3) Automatic EQ curve

 

(Gain constant) and (threshold) are user parameters.

Gain reduction for each band uses a peak filter centered at fc and the Q factor of the corresponding bandwidth.
