AudioTTo

Audio Transcription, Slide Integration & LaTeX Notes Generation

Transform your audio recordings into structured, professional LaTeX notes instantly.

---

📖 Overview

AudioTTo is a powerful Python application designed to streamline the process of creating study notes. It takes audio recordings (lectures, meetings, etc.) and optionally PDF slides, then uses advanced AI to generate comprehensive LaTeX documents.

✨ Key Features

• 🎙️ Local Transcription: Uses Faster-Whisper for fast, accurate, and private audio transcription.
• ✂️ Efficient Processing: Automatically chunks audio for parallel processing, maximizing CPU usage.
• 🧠 AI-Powered Notes: Leverages Google Gemini AI to synthesize transcripts into structured LaTeX notes.
• 🖼️ Visual Integration: Extracts images from PDF slides and embeds them directly into the notes where relevant.
• 🚀 Modern UI: Includes a user-friendly web interface for easy drag-and-drop operation.

• A LaTeX Distribution installed and added to your PATH (required for PDF compilation). You can download it manually or use the included helper scripts:
  • Windows: MiKTeX (Recommended) or TeX Live
    • Alternative: Run Install_MiKTeX.bat included in the folder.
  • macOS: MacTeX
    • Alternative: Run install_deps_mac.sh included in the folder (requires Homebrew).
  • Linux: Tex Live
    • Alternative: Run install_deps_linux.sh included in the folder or run sudo apt install texlive.
• A Google Gemini API Key. You can get one from Google AI Studio.

3. Configure: Click the Settings (⚙️) button to enter your Gemini API Key.
4. Process:
   • Drag & drop your Audio file.
   • (Optional) Drag & drop your Slides (PDF).
   • Click Start Processing.

💻 Option 2: Command Line Interface (CLI)

For automation or headless environments.

Set your API Key first: Create a file named .env in the root directory of the project. Open it with a text editor and add your API Key:

GEMINI_API_KEY = your_actual_api_key_here

Run the script:

# Basic transcription
python AudioTTo.py lecture.wav

# With specific threads
python AudioTTo.py lecture.wav --threads 4

# With slides
python AudioTTo.py lecture.wav --slides slides.pdf

# With specific slide pages
python AudioTTo.py lecture.wav --slides slides.pdf --pages 1-15

# With slides and specific threads
python AudioTTo.py lecture.wav --slides slides.pdf --threads 4

📂 Output Structure

All generated files are organized in the output/ directory:

output/
└── [Audio_Filename]/
    ├── [Audio_Filename]_trascrizione.txt  # Raw text transcript
    ├── [Audio_Filename]_appunti.tex       # Generated LaTeX source
    └── [Audio_Filename]_appunti.pdf       # Final compiled PDF

🧹 Intermediate files (chunks, noisy audio, logs) are automatically cleaned up.
