Purpose

EQ shapes tone with three peaking bands: low, mid, and high. Each band has its own frequency, boost or cut, and bandwidth, plus a master output level. It is the everyday tone-shaping node for balancing a source or a bus.

TouchDesigner Use

Insert it inline on a source or a mix bus. Wire audio into in and out onward. Set each band frequency, then boost or cut its gain, and narrow or widen with Q. Use Master to make up level after large cuts or boosts.

Inputs And Outputs

• Input 0: in accepts mono or stereo PCM. It is required.
• Output 0: out emits the same shape as the input.

Main Controls

• Lowgain, Midgain, Highgain: boost or cut per band, in decibels, from -24 to 24.
• Lowfreq, Midfreq, Highfreq: center frequency per band, in Hz.
• Lowq, Midq, Highq: bandwidth per band. Higher Q is narrower and more surgical.
• Master: overall output level after the bands.

Notes

• All three bands are peaking filters, so each boosts or cuts around its center rather than shelving the extremes.
• For surgical cuts use a high Q on the offending frequency. For broad tone shaping use a low Q.
