With the Freesound API you can browse, search, and retrieve information about Freesound users, packs, and the sounds themselves of course.
In order to use the Freesound API you need to be authenticated with an API key. You can manage your existing API keys or apply for a new one in the following url http://freesound.org/api/apply (Freesound login is required).
If you need more help after reading the documentation or want to stay up to date on any changes or future feaures of the Freesound API or if you would like to request more features for the API, please use our google group: http://groups.google.com/group/freesound-api.
Freesound is an open-source project and we will be very happy to get more people involved in its development! We coordinate using a Github public repository to host the code, organize the work to do and discuss about specific implementation aspects. Furthermore, we also have a google group to discuss about more general ideas and future directions of Freesound (http://groups.google.com/group/freesound-dev). If you want to contribute, don't hesitate to contact us!
