v1.4.0:
- Added a Range parameter to set the gain reduction limit.
- Added a setting to show the maximum gain reduction value when enabled.
- Fixed a bug where LR Linking would have no effect in some cases and remain at 100%.
- Fixed a bug where the level meter would not display MS in MS mode.
- Fixed a bug where stereo channel settings for priority curve bands were not saved.
v1.3.0
- We are pleased to introduce SpecCraft, which now features Zero Latency Mode!
- By default, SpecCraft, like many other frequency-oriented processors, uses a linear phase filter,
which is optimized for mixing but has significant latency. SpecCraft now features Zero Latency Mode,
which, when enabled, switches to a minimum phase filter for zero-latency processing. - This makes SpecCraft suitable for a wider range of real-time intensive applications.
- Zero Latency Mode can be activated with a single click using the speaker icon in the top right corner.
Bug Fixes:
- Fixed an issue where CPU usage was abnormally high on some machines.
- Fixed an issue where line thickness settings in theme configurations were not being applied correctly.
- Fixed inaccuracies in the modification status of presets.
- Fixed several typos.
