**Brand Description: AcousticBrainz**

AcousticBrainz is an innovative project that played a pivotal role in crowdsourcing acoustic information from music recordings between 2015 and 2022. Developed as a collaborative effort between the Music Technology Group at Universitat Pompeu Fabra in Barcelona and the MusicBrainz project, AcousticBrainz focused on deriving comprehensive acoustic characteristics of music, including spectral details, genres, moods, keys, and scales.

At the core of this initiative is the Essentia toolkit, an open-source software that automates music analysis, making the extensive data generated accessible to the public. Although the project ceased data collection in 2022, the website and its API continue to provide valuable resources. Users can easily access the indexed data based on MusicBrainz IDs for recordings. The entire dataset is publicly available under the CC0 license, ensuring unrestricted access to music researchers and enthusiasts. AcousticBrainz serves as an invaluable tool for exploring the intricate acoustic landscapes of music.
