aQ-31 is a traditional 31-band graphic equalizer plug-in with a clean sound. It has switchable gain range +/- 6/12/18/24 dB per band and Q-knob to adjust the filter's bandwidth; this knob allows you to make the equalizing curve more glossy or sharp.
aQ-31 v1.0 includes four versions:
- aQ-31m - mono
- aQ-31s - stereo
- aQ-31lr - stereo dual channel
- aQ-31ms - stereo with mid-side dual channel
