Dry/Wet Mix	How much of the effect you hear. 100% is the full radio sound. Lower values mix in your normal voice.

Base Radio Tuning

Radio FX limits speech to 300 to 3000 Hz before and after adding radio texture. Change these to adjust the tone.

Each can be set from 0 to 20000.

Tick Enable Equalizer to add up to 16 bands after the base effect. Click Add band to add one.

The default bands are a low shelf at 250 Hz (-3 dB), a peak at 1200 Hz (+2 dB), and a high shelf at 4500 Hz (-2 dB).

Dynamics (Expander + Limiter)

Setting	Description
