Nothing is boosted in the plug-in due to the possible introduction of clipping. Visualize a graphic equalizer with the controls set in a diagonal line with the lowest frequency band set to no attenuation and the higher-frequency bands set for gradually increasing attenuation (decreasing levels). Less attenuation is applied as the frequency decreases, with no attenuation of the lowest band (25 Hz). The one control, “warmth”, is the amount of attenuation in dB that will be applied to the highest frequency band (16 kHz). It attenuates high frequencies in a diagonal ramp across the audio band. It is designed to add “warmth” to a recording and works well with male vox by simulating proximity effect, like working a ribbon mic up close. Below is code for a bass tilt plug-in adapted from the 15-band equalizer plug-in by Josu Etxeberria and David Sky.
