+# 🎵 WAV zu MP3 Konverter
+
+Ein einfaches, benutzerfreundliches Python-Tool mit grafischer Oberfläche (Tkinter), das WAV-Dateien in MP3-Dateien konvertiert. Es unterstützt automatische Metadaten-Erstellung (Künstler, Album, Titel, Tracknummer) und fügt sogar ein Cover-Bild ein. Alle Dateien werden automatisch alphabetisch sortiert.
+
+---
+
+## ✅ Features
+
+- 📂 Mehrere WAV-Dateien auswählen
+- 📝 Standard-Metadaten definieren (Künstler, Album, Cover)
+- 🧠 Vorschau & Bearbeitung der Metadaten vor der Konvertierung
+- 🔄 Automatische Sortierung nach Dateinamen
+- 🖼️ Cover-Bild einfügen
+- 💾 Einstellungen werden gespeichert (Metadaten & letzter Export-Ordner)
+- 📊 Fortschrittsbalken während der Konvertierung
+
+---
+
+## 🛠️ Installation
+
+Damit das Programm reibungslos funktioniert, gibt es Installationsskripte, die automatisch alle benötigten Komponenten (`Python`, virtuelle Umgebung, Abhängigkeiten sowie `FFmpeg`) für dein System herunterladen und einrichten.
+
+### 🍏 macOS
+1. Öffne ein Terminal und navigiere in das Verzeichnis deines Projekts, oder speziell in den `install` Ordner.
+2. Mache das macOS Installationsskript ausführbar und führe es aus:
+   ```bash
+   cd install
+   chmod +x install_macos.sh
+   ./install_macos.sh
+   ```
+   *Dieses Skript nutzt Homebrew, um `python` und `ffmpeg` zu installieren, erstellt eine isolierte virtuelle Umgebung und lädt die benötigten Python-Bibliotheken herunter.*
+
+### 🪟 Windows
+1. Wechsle in den Unterordner **`install`**.
+2. Mach einen **Rechtsklick** auf die Datei **`install_windows.ps1`** und wähle **"Mit PowerShell ausführen"**.
+   *Dieses Skript prüft und installiert `python` und `ffmpeg` mithilfe von WinGet, erstellt dann eine virtuelle `.venv` und installiert die nötigen Pakete.*
+
+---
+
+## 🚀 Anwendung starten
+
+Nach der erfolgreichen Installation, kannst du den Konverter immer kinderleicht starten:
+
+- **Auf macOS:**
+  Führe **`start.sh`** aus dem Hauptverzeichnis aus. Entweder per Terminal (`./start.sh`) oder per Rechtsklick -> "Öffnen mit" -> "Terminal".
+
+- **Auf Windows:**
+  Einfach einen Doppelklick auf die Datei **`start.bat`** im Hauptverzeichnis ausführen.
+

+- Nur `.wav`-Dateien werden akzeptiert.
+- Cover müssen eine `.jpg`- oder `.jpeg`-Datei sein.
+- Export erfolgt im `.mp3`-Format, z.B. benannt nach dem Originaldateinamen.
+- Metadaten können vor jeder Konvertierung überprüft und angepasst werden.
