Mastering EQ
Properties
Input → five RBJ biquad bands in series (Low Shelf, High Shelf, Peaking, Low Pass, High Pass, Notch, Band Pass or All Pass per band) → Output. Solo replaces the soloed band with a band-pass and mutes the other bands' processing; Gain only affects shelf and peaking types; zero latency. The GFX and VST3/CLAP interfaces draw a real-time FFT spectrum (4096 points, Hann window, 300 ms fall) behind the EQ curve; the FFT POST / PRE / OFF selector in the display picks the output, the input or none (an interface setting, the audio is unchanged).
