Hi, I'm another researcher at the Music Technology Group, which runs Freesound. Definitely, this one of our long-time challenges. Facilitating search and exploration is one of our main research directions related to Freesound. We do audio ML research, in particular, audio-based auto-tagging (see the already mentioned Freesound Datasets https://annotator.freesound.org/fsd/ https://annotator.freesound.org/fsd/ we've built for this purpose) but also similarity and clustering based on audio analysis and tags. So far, Freesound API provides similarity search and audio analysis features. Have a look at the Freesound Explorer, which is an example of a 2D sound exploration interface built on top of audio features: https://labs.freesound.org/apps/2017/08/21/freesound-explorer.html https://labs.freesound.org/apps/2017/08/21/freesound-explore...
