How it works:

1. Extracts audio fingerprints using MFCC coefficients
2. Applies cross-correlation to find the optimal offset
3. Validates the delay across multiple segments (25%, 50%, 75%, end) for consistency
4. Reports delay, correlation score, confidence level, and time drift

Key features:
- Supports video containers (MKV, MP4, MKA) and many audio formats (WAV, AC3, AAC, DTS, FLAC, MP3, etc.)
- Multi-track selection (interactive if multiple audio tracks are found)
- Fully configurable via JSON (analysis time, sample rate, MFCC params, etc.)
- Detailed logging
- Confidence scoring with drift detection to catch VFR or different-source issues

Examples:
# Compare two audio files directly
Code:
delay-check original.ac3 dubbed.ac3
delay-check original.aac dubbed.aac
delay-check original.wav dubbed.wav
# Extract audio track from a video and compare against an audio file
Code:
delay-check movie.mkv dubbed.ac3
# Compare two video files (will use their first audio track)
Code:
delay-check original.mkv dubbed.mkv

I'd love for people to test it with their own files and report any issues or suggestions. ]]> Audio sicuskyle https://forum.videohelp.com/threads/420783-Delay-Check-Open-source-tool-to-calculate-audio-delay-between-two-files need help to download space twitter https://forum.videohelp.com/threads/420703-need-help-to-download-space-twitter?goto=newpost Sun, 14 Jun 2026 22:47:06 GMT Hello, i need help to download this space : https://x.com/melhamy/status/2065886834962358664?s=20 https://x.com/i/spaces/1wxWjjqejwwJQ thanks Hello, i need help to download this space : https://x.com/melhamy/status/2065886834962358664?s=20
