aQ-31 is a classic 31-band graphic equalizer plugin designed to deliver a clear and precise sound. It features adjustable gain ranges of ±6, 12, 18, and 24 dB for each band, allowing detailed control over the tonal balance of your audio. The plugin includes a Q-knob that adjusts the filter's bandwidth, enabling you to shape the equalizing curve to be either smooth or more defined, depending on your preferences.

This plugin offers flexibility in processing with four distinct versions tailored to different audio channel configurations. The mono version provides a straightforward single-channel equalization, while the stereo version handles two channels with ease. For more advanced control, the stereo dual channel version allows independent equalization on left and right channels, and the stereo mid-side dual channel version offers separate processing for the mid and side components of a stereo signal, enhancing creative mixing possibilities.

With its combination of traditional graphic equalizer design and multiple operational modes, aQ-31 is well-suited for detailed sound shaping in various audio production scenarios. Its clean sound character and adjustable parameters make it an effective tool for both subtle tonal adjustments and more pronounced equalization effects, fitting seamlessly into any digital audio workstation setup.
