Band EQ CHOP
The Band EQ CHOP is a 14-band equalizer which filters audio input channels in the same way that a conventional band equalizer uses a bank of sliders to filter fixed-frequency bands of sound.
The CHOP has 14 bands from 10 Hz to 82 kHz with one parameter per band. The 20 Hz band ranges from 14 Hz to 28 Hz (1 octave centred at 20 Hz). All these bands can be shifted up or down in frequency with the Base Shift parameter. The shape of each band filter can also be specified as a Gaussian (smooth falloff, where the bands overlap) or Box filter (sharp cutoff, where the bands don't overlap).
The first input contains the channels to be filtered.
The second input channels are the Filter Animation Channels, which allows the filter parameters to be changed over the CHOP's interval.
Parameters - Low Page (10-320 Hz)
Base Shift - The number of octaves to shift the bands up (positive values) or down (negative values). Each octave shifted up doubles each of the bands' frequencies.
Filter Shape - Selects the band filter type to use. Gaussian produces a smooth filter, while Box is a filter with a sharper frequency cutoff but more unintended audible artifacts.
10 Hz - 3200 Hz Bands - Controls boost/cut at the 10, 20 40, 80, 160, 320 Hz bands.
Parameters - High Page (640 - 82KHz)
640 Hz - 82 KHz bands - 640 Hz, and 1.28, 2.56, 5.12, 10.24, 20.48, 40.96, 81.92 KHz bands.
Parameters - Digital Page
See Digital Filter Overview (Pass Filter CHOP) for a full description of digital filters and the parameters on this page.
Filter Chunk - The size of the chunk that is processed at one time, in samples.
Chunk Overlap - The portion of the chunk to overlap with the previous one.
Chunk Discard - The portion of the chunk to discard.
