+*   **🎨 White-Labeling**: Upload your custom company logo.
-    ```bash
-    brew install ffmpeg
-    ```
-*   **Infomaniak AI Account**: You need an API Key and Product ID from the [Infomaniak Developer Portal](https://manager.infomaniak.com/).
-
-### 2. Installation
-1.  Download the latest `.dmg` file from the [Releases page](#).
-2.  Open the `.dmg` and drag **Hearbit AI** to your Applications folder.
-3.  Launch the app.
-
----
-
-## 🎧 Recording System Audio (Teams, Zoom, etc.)
-
-We've made this easy! **Note: You must have the BlackHole driver installed.**
-
-1.  **Create "Hearbit Audio" Device**:
-    *   Open the app and select **Meeting** mode.
-    *   If you don't have the device yet, click the **"🪄 Create Hearbit Audio Device"** button.
-    *   This creates a specialized "Multi-Output Device" that routes audio to both your headphones/speakers AND the app.
-
-2.  **Configure Teams / Zoom / Webex**:
-    *   **Speaker / Output**: Change this to **Hearbit Audio**.
-        *   *Why?* This ensures the audio goes to the recording app *and* your ears.
-    *   **Microphone / Input**: Leave this as your normal microphone (e.g., MacBook Pro Mic).
-        *   *Note:* Do **not** select Hearbit Audio as your microphone in Teams.
-
-3.  **Start Recording**:
-    *   In Hearbit AI, ensure **Hearbit Audio** is selected as the input.
 
 ---
 
 ## 🛠️ Usage Guide
 
-1.  **Configuration**:
+### 1. Installation
-    *   Click the **Settings** (gear icon).
+1.  Download the latest `.dmg` file from the [Releases page](#).
-    *   Enter your **Infomaniak API Key** and **Product ID**.
+2.  Open the `.dmg` and drag **Hearbit AI** to your Applications folder.
+3.  **Permission Check**: On first launch, grant "Screen Recording" permission (required for capturing System Audio).
 
-2.  **Connect M365 (Optional)**:
+### 2. Configuration
-    *   Copy the **Application (client) ID**.
+1.  Click **Settings** (gear icon).
-    *   Click the **Meetings** tab.
+2.  Enter your **Infomaniak API Key** and **Product ID**.
-    *   Enter your **Client ID** and click "Connect".
+3.  (Optional) Configure **SMTP** for email sending and **Microsoft 365** for calendar integration.
-    *   Proceed with MS login.
-    *   View your upcoming meetings.
 
-3.  **Recording**:
+### 3. Recording a Meeting
-    *   Choose your **Template** (e.g., "Meeting Protocol").
+1.  **Select Mode**: Choose "Meeting" (captures Mic + System) or "Voice Memo" (Mic only).
-    *   Select your **Input Device**.
+2.  **Auto-Start Logic**: 
-    *   Click **Start Recording**.
+    - **Meeting Mode**: Triggers only when the call actually starts (system audio detected).
+    - **Voice Memo**: Triggers immediately when you start speaking.
+3.  **Standby**: Click "Standby (Auto-Start)". The app waits silently.
+4.  **Join Call**: Join your Teams/Zoom call.
+5.  **Trigger**: Hearbit starts recording automatically based on the selected mode.
+6.  **Finish**: When the call ends (silence > 25s), Hearbit stops, transcribes, summarizes, and **goes back to Standby** for the next call.
 
-4.  **Processing**:
+### 4. Optimal Setup (MS Teams / Zoom / 3CX)
-    *   Click **Stop** when finished.
+For the best experience without changing any software settings:
-    *   The app will transcribe the audio (with timestamps!) and generate a summary based on your selected template.
+*   **Hearbit App**: Select your **real microphone** (e.g., "MacBook Mic" or Headset).
-    *   You will be automatically taken to the **Transcription** tab to review the results.
+*   **Meeting Software**: Use your standard output (Speakers/Headset).
+*   *How it works*: Hearbit captures your voice via mic and the other side via macOS System Audio Capture automatically.
 
----
+*Note: If you choose "Hearbit Audio" (Aggregate Device) in the app, you MUST set your Teams/Zoom/3CX speaker output to "Hearbit Audio" as well.*
 
-## 🎨 Custom Branding (White-Labeling)
+### 5. Customizing Prompts
-
+You can create custom AI templates in Settings -> Prompts. Example:
-You can replace the default Livtec logo with your own company branding:
+*   **"Sales Call"**: Focus on budget, timeline, and decision makers.
-
+*   **"Daily Standup"**: Extract blockers and next steps.
-1.  Go to **Settings** (gear icon) → **Branding**.
+*   **"General Protocol"**: Standard meeting minutes.
-2.  Click **Upload Logo**.
-3.  Select your file (PNG, JPG, SVG).
-4.  The content changes immediately across the app.
-5.  *Tip*: Use a transparent PNG for best results.
-
----
-
-## 📧 Advanced Email Templates
-
-The email system supports **full HTML & JavaScript** templates. This allows for dynamic dashboards, charts, and interactive reports.
-
-**How to use:**
-1.  Go to **Settings** → **Email**.
-2.  Create a new template.
-3.  Use `{{summary}}` as a placeholder for the raw AI JSON output.
-4.  In your HTML/Script, parse it:
-    ```javascript
-    const reportData = {{summary}};
-    // Now you can use reportData.todos, reportData.updates, etc.
-    ```
-5.  Use `{{date}}` for the current date and `{{subject}}` for the meeting title.
-
-*Example*: Create a "Daily Standup Dashboard" that visualizes Blocker/Updates/Todos in a grid layout.
 
 ---
 
 ## ❓ Troubleshooting
 
 ### "Hearbit AI is damaged and can't be opened"
-This is a standard macOS warning for apps not signed with an Apple Developer Certificate. To fix it:
+If macOS blocks the app because it's not notarized:
-
 1.  Open **Terminal**.
-2.  Run the following command:
+2.  Run: `sudo xattr -cr /Applications/Hearbit\ AI.app`
-    ```bash
+3.  Enter your password and try again.
-    sudo xattr -cr /Applications/Hearbit\ AI.app
-    ```
-3.  Enter your password.
-4.  Open the app again.
 
-### Long Meetings (> 1 hour)
+### Audio cuts off at the start?
+v1.2.0 includes a **3-second buffer**. The Meeting mode now uses a more sensitive trigger (0.005 energy) to catch even quiet participants.
 
-**Automatic Handling**: The app automatically handles long recordings:
+### "Batch processing failed"
-- **MP3 Conversion**: All recordings are converted to MP3 (64kbps) for 10x compression
+This means the audio was empty or too short. Check the **Logs** tab for detailed error messages from Infomaniak. The most common cause is selecting the wrong input device or a lack of Screen Recording permissions.
-- **Chunking**: Files ≥18 MB are automatically split into 10-minute segments
-- **Processing**: Each segment is transcribed separately and merged with timestamps
-
-**Example**: A 2-hour meeting:
-1. Records as WAV (~120 MB)
-2. Converts to MP3 (~12 MB) 
-3. Stays under limit → No chunking needed!
-
-**Very long meetings** (e.g., all-day workshops):
-- Automatically chunks into segments
-- Shows progress: "Processing chunk 1/15..."
-- Merges all transcriptions seamlessly
-
-### No Audio / Can't Hear Meeting Participants

+# 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. Dies ist der moderne Apple-Standard für Audio-Capture.
+
+### Smart VAD (Intelligente Spracherkennung)
+- **Ignoriert Musik:** Die App unterscheidet jetzt präzise zwischen menschlicher Sprache und Musik.
+- **Wartebereich-Filter:** Musik im Teams-Wartebereich wird nicht mehr aufgenommen. Die Aufnahme startet erst, wenn wirklich gesprochen wird.
+
+### UI Verbesserungen
+- **Neuer Setup-Flow:** Das komplizierte Audio-Setup wurde entfernt.
+- **Freie Wahl:** Nutzen Sie jedes Mikrofon, das Sie möchten.
+
+## 🛠️ Technische Änderungen
+- Update auf `screencapturekit` Framework (macOS 12.3+ erforderlich).
+- BlackHole-Abhängigkeit entfernt.
+- Audio-Mixing direkt in der App.
