A Simple Equalizer for "Audio>Primary Microphone"!
Add a EQ to the primary microphone! Reduce the mud or brighten your tone to get a clear broadcasters voice.
Setting UI idea could be a simple 3 gain sliders with pre-fixed frequencies (low, mid, high, with -6/+6dB range).
For the "Advanced Options", reveal access to the "Mid EQ" frequency setting, bandwidth control, and a option to enable/disable a fixed high-cutoff filter for cutting out low sub/inaudible noise.
or possibly just without the bandwidth control, to keep the interface from being too crowded with controls. So we have 4-5 sliders and 1 on/off button.
