Cavern 1.6 - Happiest Halloween update

Released: 31st October 2022.


Driver changes

  • E-AC-3 + JOC (Dolby Digital+ Atmos) visualization and rendering

QuickEQ additions

  • Added Expert crossover for complete cutoff frequency and subwoofer matrixing control.
  • Added MultEQ-X support
  • Added one-click Equalizer APO export
  • Added the Smoother curve which keeps the system's character and does not require a dedicated measurement microphone
