AudioSyncPro

AudioSyncPro is a powerful, open-source tool designed to synchronize high-quality audio recordings with video footage. It is built for musicians, videographers, and content creators who need precise alignment between their video source (camera audio) and an external high-quality audio track (recorder/interface) or Music.

Features

• Visual Synchronization: Fast, hardware-accelerated waveform visualization to manually align tracks with millisecond precision.
• Auto-Alignment Tools:
  • Peak Match: Automatically align the highest peaks in both tracks.
• Audio Drift Correction: Fix synchronization issues where audio gradually drifts out of sync over time (common with different sample rate clocks) using the Drift Tool.
• BPM Grid Detection: Detect the tempo (BPM) of your music and overlay a rhythmic grid to ensure perfect alignment with the beat.
• Noise Reduction: Apply visual noise gating to see peaks clearly even in noisy camera audio.
• Fast Performance: Uses FFmpeg direct piping for near-instant loading of large video files.
• Export: Mux the synchronized HQ audio with the original video into a final MP4 file ready for sharing.

Installation

Prerequisites

• Python 3.8+
• FFmpeg (Must be installed and in your system PATH)

Dependencies

Install the required Python libraries:

pip install -r requirements.txt

(Dependencies include: PyQt6, numpy, opencv-python, scipy, moviepy)

Usage

1. Run the application:

   python main.py

2. Load Video: Select your video file (MP4, MOV, etc.).
3. Load Audio: Select your high-quality audio file (WAV, MP3, etc.).
4. Synchronize:
   • Use the Zoom slider to inspect the waveforms.
   • Drag the waveform to shift the HQ audio.
   • Use Tools > Beat Detection to generate a grid for rhythmic alignment.
   • Use Tools > Audio Drift if the sync is lost towards the end of the video.
5. Export: Click "EXPORT FINAL VIDEO" to save the result.
