v0.4.9

ArSonKuPik OBS Audio Enhancer v0.4.9

Highlights

• Crackle-free slider movement for the OBS filter.
• Continuous knobs now use professional-style 80 ms smoothing, so aggressive mouse movement does not create zipper noise.
• EQ rebuild now preserves biquad history during coefficient retune, avoiding discontinuities that previously sounded like “kretek-kretek”.
• Preset changes now use an equal-power micro-fade around topology swaps to reduce pop/click artifacts.

What changed technically

• rebuild_eq() no longer clears and recreates EQ filters for ordinary knob automation.
• Butterworth Q values now come from static tables, avoiding repeated small allocations during retune.
• OBS wrapper no longer pushes every UI event directly into the engine. It stores target parameters, smooths them per audio block, then applies the smoothed runtime state.

User-facing result

• Move Enhance, Smart Bass, Smart Treble, Vocal Body, Stereo Magic, and Output Trim while audio is playing: the sound should change smoothly instead of crackling.
• Switching presets should feel cleaner and more like a professional VST-style audio plugin.

Notes

This release focuses on audio-thread safety and automation smoothness. It does not intentionally change the core tonal target of the presets.
