This application allows you to upload video files, extract the audio content, and generate acoustic fingerprints.

How It Works:

1. Upload your video file and select a geographical region
2. The system extracts the audio track from your video
3. Our algorithm generates acoustic fingerprints (perceptual hash values)
4. All data is stored in a database with geographical association
5. You can view the processing results and fingerprint statistics
