        <p class="essnt-about__text">
          Essentia is a open-source C++ library for audio analysis and audio-based music information retrieval. It contains an extensive collection of algorithms including audio input/output functionality, standard digital signal processing blocks, statistical characterization of data, and a large set of spectral, temporal, tonal and high-level music descriptors.

Essentia is cross-platform and it is designed with a focus on optimization in terms of robustness,  computational speed and low memory usage, which makes it effective for many industrial applications. The library is also wrapped in Python and includes a number of command-line tools and third-party extensions, which facilitate its use for fast prototyping and allow setting up research experiments very rapidly.
