Binaural Beat Generator and Mixer

This project is a Binaural Beat Generator and Mixer that creates binaural beats and mixes them with a video file. The resulting output is a video file with the generated binaural beats as audio.

Features

• Generate binaural beats with customizable frequencies for the left and right ears.
• Set the volume of the binaural beats.
• Optional frequency transition for binaural beats over time.
• Mix the generated binaural beats with an existing video file.
• Save the final video with the mixed audio to an SQLite database.

Requirements

• Python 3.6+
• ffmpeg installed and accessible via the command line
• Dependencies listed in requirements.txt

Installation

1. Clone the repository:

   git clone https://github.com/yourusername/BinauralBeatGenerator.git
   cd BinauralBeatGenerator

2. Install the required Python packages:

   pip install -r requirements.txt

3. Ensure ffmpeg is installed and accessible from the command line. You can check this by running:

   ffmpeg -version

   If ffmpeg is not installed, you can download and install it from FFmpeg.org.

4. Please note the included binaural_frequencies file added, and refer to it as needed to create the proper binaural tones.

Usage

1. Place the video file you want to mix the binaural beats with in the same directory as the script.

2. Run the main script:

   python main.py

3. Follow the prompts to input the necessary parameters:

   • Sample rate (e.g., 44100 for CD-quality audio)
   • Duration of the binaural beats (in seconds)
   • Frequency for the left ear (in Hz)
   • Frequency for the right ear (in Hz)
   • Volume (e.g., 1.0 for 100%, 0.5 for 50%)
   • Frequency transition rate for left and right ears (optional)
   • Name of the video file (including the file extension, e.g., video.mp4)
   • Desired name for the output file (including the .mp4 extension)

4. The script will generate the binaural beats and mix them with the provided video file, producing an output file named as specified by the user. You will be prompted to save this output file to the SQLite database.
