Audio Video Recorder

A Python application for simultaneous audio and video recording with timestamp synchronization.

Features

• Simultaneous audio and video recording
• Timestamp synchronization between audio and video streams
• Configurable recording duration
• Support for multi-channel audio input
• Automatic file organization with timestamped folders

Requirements

• Python 3.8+
• OpenCV
• NumPy
• SoundDevice

Installation

1. Clone the repository
2. Install dependencies:

   pip install -r requirements.txt

Usage

Basic usage:

from src.recorder import AudioVideoRecorder

# Create a recorder instance
recorder = AudioVideoRecorder(
    mic_device_name="UMA16V2",  # Your audio device name
    video_device_index=0,       # Video device index (usually 0 for default camera)
    duration=2700              # Duration in seconds (45 minutes)
)

# Start recording
recorder.start_recording()

Output

The recorder creates two directories for each recording session:

• data/audio_stream_[timestamp]/: Contains audio chunks in NumPy format
• data/video_stream_[timestamp]/: Contains the video recording in MP4 format

Notes

• Make sure your audio device is properly connected and recognized by the system
• The video device index might need to be adjusted based on your system configuration
• The default recording duration is 45 minutes (2700 seconds)
