v0.4.14

ArSonKuPik OBS Audio Enhancer v0.4.14

Highlights

• Delivers a consistent immediate ON/bypass wow effect across every factory preset.
• Preserves the v0.4.13 real-time hardening for crackle-free parameter changes, lower CPU cost, and stable dynamics.
• Uses a fixed per-preset calibration instead of a moving loudness AGC, so the level benefit does not chase the source or recreate pumping.

Preset wow calibration

• Moderate macro values now use slightly stronger response curves, so Mastering, Audiophile, Movie, Podcast, Night Listening, and other restrained presets sound more clearly processed while preserving their own tonal identity.
• Every factory preset receives a fixed source-independent calibration trim.
• The maintained smoke signal measures both RMS and peak benefit for every preset.
• Required factory-preset window: approximately +3 dB RMS, with transient peak benefit guarded below +4.7 dB and no clipping.

Real-time architecture retained from v0.4.13

• UI updates publish only atomic numeric values and flags. Preset names and std::string values never cross into shared audio-thread state.
• DSP engines are prepared and mutated only by the OBS audio callback.
• Preset changes are prepared in a second engine and crossfaded for 10 ms; no remainder of the OBS block is muted.
• Continuous macro automation uses a fixed 96-stage-capacity biquad bank with stable stage count inside each preset.
• Repeated macro retuning is allocation-free after initialization.

CPU and stability

• Compressor attack/release coefficients, limiter release/ceiling/drive, width-detector coefficients, and linear input/output gains are cached.
• Compressor transfer calculation runs at an interpolated 8-sample control rate.
• Stereo analysis runs every 16 samples using true energy correlation.
• Meter conversion runs once per audio block instead of once per sample.
• Parallel compression uses unity-preserving linear dry/wet mixing.
• Gain staging keeps fixed -8 dB creative-chain headroom with calibrated restore; there is no dynamic full-band makeup AGC.

Preset calibration results

The maintained 48 kHz stereo smoke signal produced the following default ON/bypass differences:

Preset	RMS benefit	Peak benefit
MasAri	+3.10 dB	+4.41 dB
Mastering Global	+3.07 dB	+3.82 dB
Max Enhancer	+3.16 dB	+4.03 dB
SonKuHoreg	+3.10 dB	+4.28 dB
SonKuBattle	+3.00 dB	+4.55 dB
SonKuBalap	+3.00 dB	+4.37 dB
Audiophile	+3.08 dB	+3.66 dB
Punchy Music	+3.27 dB	+3.95 dB
Open Air	+3.06 dB	+3.85 dB
Movie Sub	+3.00 dB	+4.15 dB
Podcast	+3.02 dB	+3.88 dB
Night Listening	+3.00 dB	+3.80 dB

No preset clipped in this calibration run.

Hardening regression results

• Automation maximum-jump ratio versus static render: 1.00071× (limit: 1.10×).
• Limiter stress-test output peak: -1.90 dBFS.
• Correlation meter: +1.000 for identical stereo and -0.999996 for inverted stereo.
• Bass-linked pumping test variation: 0.0057 dB.
• Realtime parameter/process allocation test: 0 allocations after initialization.
• AddressSanitizer and UndefinedBehaviorSanitizer standalone tests: passed.

Listening boundary

The numeric gates prevent quiet-preset regressions, extreme hidden boosts, clipping, allocation regressions, and known hardening failures. Final approval also includes listening in native OBS with music, voice, bass-heavy material, rapid knob movement, repeated preset switching, and several plugin instances.

v0.4.12

ArSonKuPik OBS Audio Enhancer v0.4.12

Highlights

• Recalibrates gain staging after the stronger v0.4.11 VST-style macro controls.
• Keeps the audible knob movement, but prevents Filter ON from becoming a large hidden volume boost.
• Adds an internal -8 dB creative-chain headroom trim before the DSP rack, with only partial calibrated restore afterward.

What changed

• The creative rack now receives lower internal level so EQ, color, compressor, and width stages have cleaner headroom.
• Smart makeup is capped lower and rises more conservatively.
• Compressor makeup and parallel density are reduced so bass-heavy content does not feel like it is pumping.
• Output gain mapping is recalibrated so the main MasAri preset targets roughly +3 to +4 dB benefit in the smoke test instead of a very large level jump.
• The DSP smoke test now fails if the main preset moves outside the calibrated target or if any preset creates an extreme hidden boost.

Test result

• MasAri smoke-test peak benefit: about +3.41 dB.
• SonKuHoreg smoke-test peak benefit: about +3.48 dB.
• SonKuBalap smoke-test peak benefit: about +3.92 dB.
• SonKuBattle remains the hottest stress preset at about +4.63 dB, still below the extreme boost guard.
• Clipping: no.

Notes

This release intentionally does not weaken the v0.4.11 macro feel. The fix is gain staging: more internal headroom, lower restore, and tighter smart makeup.

v0.4.11

ArSonKuPik OBS Audio Enhancer v0.4.11

Highlights

• Ported the stronger askp-vst style macro control behavior into the OBS engine.
• Smart Bass, Smart Treble, Vocal Body, and Stereo Magic now react more clearly when moved from minimum to maximum.
• Kept the v0.4.10 crackle-free smoothing, CPU-safe dirty apply behavior, and stable no-pumping makeup guard.

What changed

• Smart Bass is now bipolar: left cleans rumble/mud, center is neutral, right adds sub/body/punch.
• Smart Treble is now bipolar: left smooths harshness/sibilance, center is neutral, right adds air/presence/sparkle.
• Vocal Body is now bipolar: left tucks/smooths vocal, center is neutral, right moves vocal forward with body and clarity.
• Stereo Magic is now bipolar: left narrows toward mono, center is raw/neutral, right widens/open side air.
• Macro EQ lanes stay allocated in a stable order so slider automation remains crackle-safe.

Testing focus

• Sweep each knob from 0 to 100 while audio is playing.
• Confirm the effect is clearly audible without zipper noise.
• Confirm bass-heavy sources do not create obvious pumping.
• Confirm Stereo Magic at minimum narrows strongly and at maximum opens the image.

Notes

This release is a feel/behavior release. It makes the four main creative knobs more useful while preserving the crackle-free and CPU-conscious architecture from v0.4.10.

v0.4.10

ArSonKuPik OBS Audio Enhancer v0.4.10

Highlights

• Crackle-free slider movement with a lighter CPU path.
• Continuous OBS knobs use 80 ms smoothing, snap-to-target, and dirty-apply behavior so the engine does not retune forever after controls settle.
• EQ retuning preserves biquad history, preventing filter-state discontinuities during automation.
• Smart makeup recovery is slower while peak protection reacts faster, reducing audible pumping on dense music.

User-facing result

• Moving Enhance, Smart Bass, Smart Treble, Vocal Body, Stereo Magic, and Output Trim while audio is playing should feel smooth instead of crackly.
• Normal playback after controls settle should be lighter on CPU because retuning stops when the target is reached.
• Loudness benefit remains, but gain recovery is calmer to avoid obvious breathing/pumping.

Technical notes

• rebuild_eq() is state-preserving for same-topology retunes.
• Butterworth Q values use static tables instead of repeated vector allocation.
• OBS wrapper stores target parameters, smooths them per audio block, and applies runtime state only while parameters are changing.
• Preset switching still uses an equal-power micro-fade around topology swaps.

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.

v0.4.8

ArSonKuPik OBS Audio Enhancer v0.4.7

Highlights

• Refreshed the public README with the new hero image, stronger product positioning, clearer download guidance, and a more professional open-source presentation.
