EXCITER

EXCITER - Aphex Aural Exciter

This effect is inspired by the Aphex Aural Exciter. The cutoff frequency of the high-pass filter in the sidechain before the harmonic generation is set with the TUNE knob. The graph below shows the frequency response of the output signal for three different TUNE settings (1 kHz, 5 kHz and 10 kHz). Note that there is a dip in the frequency response right before the harmonic generation. This is due to the recombination of the sidechain and the unprocessed input signal.

The PEAK control accentuates the TUNE frequency, as shown in the graph below. However, the dip before the TUNE frequency also becomes more pronounced as the PEAK increases. For this example, the TUNE frequency remains constant at 1kHz.

The ZERO FILL control compensates for the dip before the TUNE frequency. In the example below, both the TUNE and PEAK controls remain constant.

Turning the TIMBRE knob counterclockwise adds more odd harmonics, while turning it clockwise adds more even harmonics. Adjust the amplitude of the harmonics added to the signal with the HARMONICS knob, and blend in the effected signal with the MIX knob. Disengage the DRY button to listen only to the harmonics that are being added.
