Audio-to-Notes

Audio-to-Notes is a Python application that streamlines the process of transcribing audio files and generating concise notes using state-of-the-art AI models. It features a simple command-line interface for processing audio files, and leverages OpenAI Whisper for transcription and OpenAI's GPT-4o for note generation.

• Automatic Processing: Monitors a folder for new audio files and processes them automatically.
• Automatic Transcription: Uses OpenAI Whisper for accurate speech-to-text transcription.
• AI-Powered Notes: Summarizes transcriptions into clear, concise notes using OpenAI's GPT-4o API.
• Organized Output: Saves both transcription and notes with filenames containing the original title, current date/time, and a descriptive suffix.
• Robust File Handling: Handles audio conversion (via ffmpeg) and long file chunking for optimal processing.

2. Using the GUI:
   • Click the button to select an audio file (any supported format).
   • Enter a descriptive title in the textbox.
   • Click the button to start processing.
   • The app will:
     • Convert the audio to a compatible format if needed.
     • Transcribe the audio using OpenAI Whisper.
     • Save the transcription as <title>-<datetime>-transcription.txt.

Example

Suppose you have an audio file meeting.m4a and want to generate notes titled "Team Meeting". The app will produce files like:

• Team Meeting-2025-05-18-15-30-12-transcription.txt
• Team Meeting-2025-05-18-15-30-12-notes.txt

---

Troubleshooting

• ffmpeg Not Found: Install ffmpeg using your system package manager (see above).
• OpenAI API Errors: Make sure your API key is valid and has sufficient quota.
• tkinter Not Installed: On some Linux systems, install with sudo apt-get install python3-tk.
