Freesound API

With the Freesound API you can browse, search, and retrieve information about users, packs, and the sounds themselves of course. You can find similar sounds to a given target (based on content analysis) and retrieve automatically extracted features from audio files, as well as perform advanced queries combining content analysis features and other metadata (tags, etc...). With the Freesound API, you can also upload, comment, rate and bookmark sounds.

The Freesound API is a tool that can be used by researchers and developers in order to programatically interact with Freesound and retrieve research data or embed sounds in third-party applications. Freesound API usage is free for non-commercial use, but it can also be licensed to be used in commercial applications. 

Freesound is a community-driven repository of sound samples that was started in 2005 in our research group. One of the first aims behind Freesound was creating an open database of sounds that could also be used for scientific research. Currently, Freesound is one of the most popular sound sharing sites in the world. Freesound (and the Freesound API) is being maintained and developed at the MTG by the Freesound team, which is basically composed by current and former researchers and students of the research group.

Freesound aims to create a huge collaborative database of audio snippets, samples, recordings, bleeps, ... released under Creative Commons licenses that allow their reuse. Freesound provides new and interesting ways of accessing these samples, allowing users to:

  • browse the sounds in new ways using keywords and content-based queries, a "sounds-like" type of browsing and more
  • upload and download sounds to and from the database, under the same creative commons license
  • interact with fellow sound-artists!
