Release DDCToolbox v2.0 · timschneeb/DDCToolbox

Feature updates

Advanced peaking filter curve fitting
- Backend library provided by @james34602 (see james34602/libgradfreeOpt)
- Available algorithms: Differential evolution, bounded simplex search, flower pollination search, CHIO, and various hybrid optimization combinations
- Inspect the optimization history and MSE plot in real-time
Full macOS support and integration
- Precompiled macOS binaries for Intel-based devices
- .vdcprj files are automatically associated with the app and can be directly opened from Finder
New export options
- Export as EqualizerAPO IIR configuration (EAPO version 0.9 or later only)
- Export biquad coefficients as CSV dataset
New stability check dialog
- More detailed error descriptions
- VDCs cannot be exported anymore when at least one filter is unstable
Highlight unstable filters in the table
Windows shell integration for .vdcprj files (only available if installed using setup-executable)
Allow vertical layout orientation (press F4 or check 'View > Switch orientation')
Display detailed coefficient values of custom filters as a tooltip when hovering over their corresponding table rows
Added 'recent projects' sub-list in the menu bar
Added more quick-actions in the toolbar
Added various icons for menu and toolbar actions
Full rewrite of the filter table backend (more stable and much faster; model-based instead of item-based)
Notify about unsaved changes before exiting
- Includes basic support for OS-specific session managers

Fixed undo/redo stack corruption issue when re-sorting the table columns multiple times and undoing
Backward compatibility with older Qt versions (tested with Qt 5.7)
Forcefully set the correct color scheme and prevent OSes from overwriting it
Refactored various issues marked by clang-tidy and clazy to modernize the source code
Various crash/bug fixes, stability, and performance enhancements

Windows: A proper application installer (which enables *.vdcprj file associations) is now available; please consider using it instead of portable executables
Linux: The Ubuntu PPA has been discontinued; please use the snapcraft packages instead
macOS: Precompiled binaries packaged in DMGs are now available (both stable and nightly builds). ARM-based systems are not officially supported, and users need to compile the app on these platforms themselves (check manual macOS installation in README for further instructions). Tested on OSX 10.13.

Thanks to @james34602 for various contributions regarding the new peaking filter curve fitting algorithms (see james34602/libgradfreeOpt) and more.
