AFT — acoustic fingerprinting and audio matching

Audio Fingerprinting Tools (AFT) is a proprietary patented* acoustic fingerprinting solution for reliable audio matching, comparison, identification, and large-scale monitoring by means of compact, highly representative, and robust acoustic fingerprints.

AFT highlights:

- industrial-grade acoustic fingerprinting performance providing:
    · robust and compact fingerprints
    · real-time hashing
    · on-the-fly database updates
    · instant search over very large databases (including millions of tracks)
    · scalable database architecture
- live stream and file tools
- comprehensive client-server (TCP/IP) functionality
- multi-threaded
- cross-platform software (Windows, Linux, macOS, embedded)
- console tools for automation and rapid deployment on servers
- tools for acoustic matching and identification via database lookup
- dedicated acoustic comparator (de-duplicator) tool
- SDK available
- unique, proprietary, patented* technology and algorithm
- evaluation package available upon request
- optional multi-million-track music fingerprint database

Details and a demo of the technology are available upon request.

AFT can be licensed with or without a multi-million-track music fingerprint database.


AFT applications

AFT is a scalable and flexible acoustic fingerprinting and matching solution suited to applications and use cases from the following areas:

  • Music recognition in live broadcasts or files
  • Monitoring of airplay (e.g. commercials, music, etc.)
  • Acoustic de-duplication
  • Live channel detection

How to evaluate

An evaluation (demo) version of AFT for all major desktop, server, and mobile platforms is available upon request.

All packages contain command-line (terminal) tools (acoustic hasher, recognition server, client, database manager, de-duplicator), a detailed technology manual, and a set of illustrative examples. If you are interested in integrating AFT into your software, the AFT SDK is available for all major desktop, server, and mobile platforms upon request.

Request information or evaluation

Evaluation packages are prepared individually, following an initial discussion of your use case and requirements.

AFT SonicDeCloner — Freeware music deduplication tool

AFT SonicDeCloner is a dedicated freeware audio de-duplication tool that automatically detects acoustically similar audio files (duplicates or "clones") within a folder. Instead of comparing bits and bytes, the tool actually "listens" to the sound — just like a human ear would. SonicDeCloner is based on the AFT technology.
