Changelog

Stability + battery — fixes Per-App Profiles freeze and saves up to 70% battery during silent gaps.

• Fixed freeze when opening Per-App Profiles on Realme, OPPO, OnePlus, Xiaomi, and Tecno phones.
• Fixed crash caused by apps with broken emoji in their names.
• Up to 70% less battery drain when nothing is playing — wake lock now releases during silent gaps.
• Auto-recovers if aggressive battery managers (MIUI / EMUI / ColorOS / HiOS) kill the service in the background.
• On Tecno / Infinix / Itel devices: honest warning shown — these chipsets bypass system effects, try Bluetooth output for full DSP.
• Now starts cleanly on Huawei devices without Google Mobile Services.
• Auto-preamp prevents digital clipping when boosting EQ bands — the input is now pre-attenuated by the highest peak so a +3 dB shelf at 20 Hz can't push hot masters past 0 dBFS.
• Master Gain now also takes effect on the legacy fallback path used on devices where Android's DynamicsProcessing engine isn't available (Honor MagicOS, Tecno HiOS, older Android).
• UI polish — Pro upgrade card title fits properly in long-translation locales (Russian, German, French, etc.); Cancel button on the Activate Promo Code dialog now translates; oversized Best-Value badge wrapped over the price in 10 languages.
• Visualizer runs lighter — poll rate reduced from ~30 fps to ~20 fps so budget Android devices don't lag while the spectrum is on screen.

Cleaner audio — bass is tighter and less muddy, highs are clearer with no harshness.

• Cleaner audio — bass is tighter and less muddy, highs are clearer with no harshness.
• Sharper parametric EQ — narrow peaks and notches now actually sound as sharp as they look.
• Smoother slider drags — no more tiny zipper or stair-step noise when adjusting bands.
• Better Loudness slider — at low listening volumes the mix now feels full instead of just louder.
• Steeper Low Pass / High Pass / LR2 / LR4 cutoffs — slope steepness closer to advertised dB/oct.
• Existing profiles get the upgrade automatically — no re-saving needed.

New: Master Gain slider for overall loudness control.

NEW: 10D Spatial Motion — multi-axis cinematic mode with 4 presets (Cinema, Concert, Surround, Meditation), bass-anchor toggle, and tunable intensity + speed. Real DSP layered on top of the 8D engine, not buzzword marketing.

• NEW: 10D Spatial Motion — multi-axis cinematic mode with 4 presets (Cinema, Concert, Surround, Meditation), bass-anchor toggle, and tunable intensity + speed. Real DSP layered on top of the 8D engine, not buzzword marketing.
• 3 new reverb presets: Spring (guitar-amp tank), Shimmer (long ethereal cloud), Gated (80s drum production). Cathedral preset rebuilt with much longer decay and lower diffusion for true echoey stone-cathedral feel.
• Reverb, 10D, and other Pro effects now correctly disengage when a temporary Pro unlock expires — no more lingering reverb tail after the 24-hour window ends.
• Fixed brief audio glitch + repeated "EQ active and running normally" banner that triggered every time the app was resumed from the notification pane or task switcher.
• Reduced interstitial ad frequency — fires every 10th preset apply (was 5th) with a 3-min cooldown (was 2-min). Roughly 60% fewer interruptions while you tweak.
• Carries forward the 1.2.3 hotfix chain: Auto-EQ canvas fix, L/R Balance polish, Mine tab fix, AudioEffect finalizer SIGSEGV mitigation on Oppo/vivo Android 8.1.

Auto-EQ database expanded from 95 to 8,850 headphone profiles — full jaakkopasanen/AutoEq snapshot bundled offline (oratory1990, Crinacle, Rtings, Innerfidelity, and more)

• Auto-EQ database expanded from 95 to 8,850 headphone profiles — full jaakkopasanen/AutoEq snapshot bundled offline (oratory1990, Crinacle, Rtings, Innerfidelity, and more)
• Live GitHub search retained as a delta for any profiles added after the snapshot
• Upgraded Google Mobile Ads SDK to the latest version (better fill rate, clears AdMob "install latest SDK" warning)

• Pre-emptively dropped READ_MEDIA_AUDIO request (we never read media files) for stricter Google Play policy compliance
• Hotfix: picking an Auto-EQ profile no longer blanks the parametric EQ canvas (bundled-snapshot field-shape mismatch)
• Visualizer engine rebuilt for performance: per-bin asymmetric smoother (slow-thump lows, snappy-transient highs), adaptive spectral-flux onset detector, decoupled canvas repaint (no more full-tree rebuild at 30 Hz), typed Float64List buffers, O(1) spectrogram history, cached colormap LUTs, reused Paint instances across all painters

Switched community profile photo selection to the system Android Photo Picker — no broad photo/media permission needed (Google Play "Photo and Video Permissions" policy compliance)
