Autoduck modifications

Hi mixxx users. Is there a way to modify any of the config files to speed up the autoduck time? The slow fade and rise of the volume is ideal for some, i get that, but i would prefer the autoduck of mixxx 1.2 and even version 2.0.

Unfortunately this is not currently configurable. We should expose the full controls of the compressor, not just the duck strength.

We have a feature request for Mixxx 2.4 already.
Should be no big deal to make attack time, decay time and ducking threshld configurable.
