• Python 3.6 or higher
• requests library
• tqdm library
• OpenAI API key

Installation

1. Clone the repository or download the script file.
2. Install the required Python libraries using pip:

pip install requests tqdm

3. Obtain an OpenAI API key by signing up at OpenAI.

Setup

1. Save your OpenAI API key in the script by replacing 'YOUR_API_KEY' with your actual API key.
2. Ensure you have a folder containing your audio files. create a folder called audio_files, but you can change this in the script if needed.
3. Ensure the output folder (srt_files) exists or will be created by the script.

Usage

2. Chnage audio type on the line 39.
3. Run the script:

python audio2srt.py

The script will process each audio file in the input folder, transcribe it using the OpenAI API, and save the resulting SRT file in the output folder (srt_files by default).

Notes

• Ensure you have a stable internet connection while running the script, as it communicates with the OpenAI API.
• Handle your API key with care. Avoid sharing or exposing it in public repositories.
