Extensive collection of analysis algorithms
State-of-the-art algorithms for music description with extensive industrial use available as a web API instantly accessible for any developer. Musical key, tempo (BPM), loudness, genre, mood, instrumentation, danceability, arousal, valence, approachability, engagement, and many more. 🔊🤖
Focus on building, and iterate in no time
Focus on building applications and let us do audio processing, machine learning and infrastructure.
Transparency and open innovation
Our API is based on Essentia, an open-source library and AI models for audio and music analysis under the non-commercial CC BY-NC-SA 4.0 license. It is built upon 15 years of R&D experience at Music Technology Group, Universitat Pompeu Fabra, a renown research institution in music informatics.
