AcousticBrainz

AcousticBrainz is a project that analyzes music to identify its characteristics, such as tempo, rhythm, and genre, using advanced audio analysis techniques. It collects and shares this data publicly to help musicians, developers, and researchers understand and categorize music better. Think of it as a detailed musical fingerprint database that helps improve music recommendations, playlist creation, and music research by providing insights into what makes each song unique. It operates as part of the MusicBrainz ecosystem, which aims to create an open, comprehensive database of music information.
