The Shazam mechanism revealed: this is how song recognition works

Have you ever had a song stuck in your head, but didn’t know the title or artist? Shazam, the music recognition app, comes to the rescue in seconds, unravelling the mystery behind the tune. But how does Shazam do this magic?

The answer lies in a complex process involving artificial intelligence and audio analysis. Here’s an overview of how it works.

1. The digital track: When you press the Shazam button, the app begins recording the audio of the song you are listening to. This audio is then converted into a digital track, a sound image that can be analyzed.
2. The acoustic fingerprint: Shazam uses a sophisticated algorithm to create an acoustic fingerprint of this track. This fingerprint is essentially a unique code that represents the melodic structure, rhythm and timbre of the song. Imagine a human fingerprint, but for music!
3. The Shazam database: Shazam has a vast database of acoustic fingerprints of millions of songs. Once the app has generated the fingerprint of the song you’re listening to, it compares it to the database looking for a match.
4. Searching for a match: Using processing power and artificial intelligence algorithms, Shazam quickly compares your fingerprint to the database. If it finds a match, it identifies the song and displays it on your screen.

Shazam is surprisingly fast at recognizing songs. This is due to a combination of several factors: the use of efficient algorithmsthe enormous processing power of Shazam servers, and database optimization for fast search.

In addition to recognition

Shazam doesn’t just identify songs. The app also offers additional information, such as the title, artist, music genre, lyrics and music videos.

The magic of Shazam is the result of advanced engineering and sophisticated artificial intelligence. The app has revolutionized the way we listen to musicmaking music recognition immediate and accessible to all.

The Shazam process is not only efficient but also constantly evolving. With updates and technological developments, Shazam continues to improve its accuracy and its ability to recognize even the most complex and lesser-known songs.
