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
Cavern 1.5 - Nearly 5 years update

Driver changes
- New front and center speaker models for Studio and Home layouts, new Home subwoofer model
