From 4e9a1fd0380d6a3a76392d701a4ebf049b30dd44 Mon Sep 17 00:00:00 2001 From: "michael.borak" Date: Sat, 24 Jan 2026 01:35:09 +0100 Subject: [PATCH] feat(v1.2.0): Final Release - Native Audio, Smart VAD, Auto-Loop & Quality Fixes - Implemented standard 48kHz audio pipeline to fix sample rate mismatch/distortion - Added Native System Audio (ScreenCaptureKit) support - Implemented Smart VAD (Voice Activity Detection) with Auto-Start on valid audio - Added Auto-Loop: Automatically re-arms recording after stop - Added Empty Guard: Prevents transcribing silent recordings (< 20s empty) - Increased Pre-Roll buffer to 3.0s to prevent cut-off speech - Fixed clipping with clamped audio mixing --- RELEASE_NOTES_1.2.0.md | 22 +++ package-lock.json | 4 +- package.json | 2 +- src-tauri/Cargo.lock | 81 +++++++++- src-tauri/Cargo.toml | 4 +- src-tauri/src/audio_processor.rs | 88 ++++++++--- src-tauri/src/lib.rs | 99 +++++++++++- src-tauri/src/sc_audio.rs | 103 +++++++++++++ src-tauri/tauri.conf.json | 2 +- src/components/Recorder.tsx | 253 ++++++++++++++++++------------- 10 files changed, 513 insertions(+), 145 deletions(-) create mode 100644 RELEASE_NOTES_1.2.0.md create mode 100644 src-tauri/src/sc_audio.rs diff --git a/RELEASE_NOTES_1.2.0.md b/RELEASE_NOTES_1.2.0.md new file mode 100644 index 0000000..ac29a9b --- /dev/null +++ b/RELEASE_NOTES_1.2.0.md @@ -0,0 +1,22 @@ +# Release Notes - Hearbit AI v1.2.0 + +## 🚀 Neuheiten + +### Native System Audio (ScreenCaptureKit) +Wir haben die Audio-Engine komplett erneuert! +- **Keine Treiber mehr:** Sie müssen BlackHole nicht mehr installieren. +- **Funktioniert überall:** Egal ob Teams, Zoom, Webex, Nextcloud Talk oder 3CX – die App hört jetzt nativ mit. +- **Berechtigung:** Die App fragt beim ersten Start nach der "Bildschirmaufnahme"-Berechtigung.
