The Audio Commons Ecosystem (ACE) refers to a series of technologies and actors involved in publishing and consuming Audio Commons content. Audio Commons content (AC) refers to audio released under Creative Commons licenses and enhanced with meaningful contextual information (e.g. annotations, license information) that enables its publication in the ACE and facilitates its reuse.
Several of our tools allow the navigation of vast catalogues of sound and music content which is facilitated by a common data model: the Audio Commons ontology. This is used to support a common Web Application Programming Interface for the ACE.
In the following, we present some tools for music production and discovery that have been developed and tested through our research project.

SampleSurfer from Waves Audio Ltd. provides an audio content search engine embedded in the digital audio workstation with instant listening capabilities and transparent listing of licensing terms including Creative Commons content. It also embeds tools for content manipulation and repurposing. With SampleSurfer users are able to efficiently share, use and manipulate sounds within their DAW.

AudioTexture is LeSound’s sound texture synthesis technology released as a DAW plugin. AudioTexture allows sound designers to make use of any sound texture recordings available and create new sound textures, with semantic controls, for film/TV post-production and video games.

Identifying suitable sound effects for an audio project can be a difficult task but current tools are typically limited to keyword search. Filtering and sorting sound effects by their timbral and reverberant characteristics offers a better solution. As part of the AudioCommons project we have developed perceptual algorithms capable of predicting the Hardness, Depth, Brightness, Roughness, Warmth, Sharpness, Boominess, and Reverberation of sound effects to rank, filter, or limit the range of search results, assisting users to find the sound effects they want.

Freesound is an online collaborative sound database hosting more than 380k sounds by 20k contributors and published under Creative Commons licenses that allow easy reuse and modification in both commercial and non-commercial projects. Freesound is the biggest Creative Commons sound database with120M downloads since 2005. Freesound was developed at the Music Technology Group of Universitat Pompeu Fabra, one of the leading music technology research groups worldwide.

Frederic Font explains in this blog post how to use the Audio Commons Audio Extractor with Freesound.
Jam with Jamendo
Jam with Jamendo brings music learners and unsigned artists together by recommending suitable songs as new and varied practice material. In this web app, users are presented with a list of songs based on their selection of chords. They can then play along with the chord transcriptions or use the audio as backing tracks for solos and improvisations. Using AI-generated transcriptions makes it trivial to grow the underlying music catalogue without human effort.

The Audio Commons Music and Sound Search Tool (MuSST) is a web interface that allows users to search for and browse sound and music content from several sources (online digital audio libraries) within the Audio Commons ecosystem. It includes a search feature to retrieve audio content from several providers. At the moment, the following content providers are part of the ecosystem: Freesound, a collaborative repository of CC licensed audio samples; Jamendo, a music content website and community of musicians and music lovers; Europeana, an European digital platform for cultural heritage.
The results can be sorted according to different criteria and eventually the audio files can be downloaded by users. Direct access to the source on content provider service is also made possible.

Playsound.space is a web-based tool to search for and play Creative Commons-licensed sounds. It can be used for music making in contexts such as free music improvisation, soundscape composition and sound discovery. The system provides a fast access to about 400k non-musical and musical sounds from Freesound and allows users to play and loop them in layered ways. Sound discovery and selection are facilitated by the use of semantic searches, metadata and visual sound representations (spectrograms). Aiming to design an intuitive music making tool for both novices and trained musicians, the site has also recording capabilities and attribution of credits to the original authors of the sounds from Freesound.org.

The collection of sounds can be saved as a url. For example, try the collection shown in the image above.
