Audio Band EQ CHOP

From TouchDesigner 099 Wiki


The Audio Band EQ CHOP is a 16-band equalizer which filters audio input channels in the same way that a conventional band (graphic) equalizer uses a bank of sliders to filter fixed-frequency bands of sound.

The CHOP has 16 bands from 25 Hz to 22 kHz with one parameter per band. The bandwidth per band is approximately half the frequency between the prior and next bands.
