It says to install from master for the latest updates, lists official releases on GitHub, and warns that behaviour can differ between versions.\n\n- Descriptor outputs can differ between Essentia versions, so record the version you use.\n- The README gives pip installation only for Linux x86_64 and i686; other platforms need the installation guide, which was not read.\n- The README does not list the descriptors or algorithms individually.\n\nThe README says Essentia is released under the Affero GPLv3 license. That licence has network-use obligations beyond the ordinary GPL, so read the licence before using it in a service. The licence file was not read here. Audio you analyse carries its own rights.\n\nWritten from the README text only. Statements are as the README gives them; nothing was installed or run and no audio was analysed.\nBased on README text only; the documentation site, the installation guide, the licence file and the code were not read.
