Cavern release notes

Pre-released Cavern 1.6 features

Driver changes

  • A welcome screen is shown on first launch
  • Speaker layout auto-detection on first launch
  • File browser dialogs are now Mono library popups that look like a Windows file browser

QuickEQ additions

  • 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
  • Added a custom gain standard, where channel gains can be offset between -6 and 6 dB with sliders or manually without bounds
  • Multiple microphones can be selected for measurements, these measurements are automatically added to the Multi-mic panel
  • Default calibration files are automatically applied on MiniDSP UMIK-1 and XTZ II Pro microphones
  • Arbitrary measurement signals can be used
  • Warm-up mode against microphone clicking on measurement start
  • Warning messages when channel gains are too far apart
  • Error message when no microphone is connected

QuickEQ changes

  • Measurements are now exported in Limitless Audio Format, which can contain complete multi-mic measurements
  • Minimum corrected frequency is now allowed down to 10 Hz
  • Delays and polarities are calculated after simulation for convolution exports, making them superior to any other export
  • Delays smaller than half the filter size are baked into convolution filters
  • After overwhelming user feedback, Cavern is now the default gain standard instead of DCI
  • Filter sizes other than powers of 2 are now supported for convolution exports

API additions

  • CavernAmp accelerates some features with native code on 64-bit Windows for an average of 2x speedup
  • Ear canal simulations by angle and distance with the Distancer filter
  • Optimized convolution for basic impulse responses called Spike convolver
  • Many new waveform and audio file handling functions

API changes

  • Linearized virtualizer frequency responses
