Abstract

Freesound is one of the most prominent collections of user-contributed audio samples, providing a large and heterogeneous collection of sounds for creative, educational, and research purposes. In addition to its web-browser interface, Freesound features an API that enables programmatic access to search features and sound resources, including descriptive metadata and content-based audio descriptors. As a result, third-party developers and researchers can access and integrate Freesound content in advanced ways, with applications in various fields including (but not limited to) music making, information retrieval, machine listening, interactive media, sound design, and multimodal systems. This paper surveys creative applications and sound interfaces that integrate content from Freesound, addressing a wide range of use cases that utilize it interactively. We outline their technical capabilities and use of Freesound resources, and explore emerging research directions. We focus on how these systems interact with Freesound, how its content is integrated within their overall design, and how they engage users. The study shows that Freesound has become an infrastructural and inspirational resource for creative applications and sound interfaces. Nevertheless, the study reveals that many of Freesound's API capabilities remain underused, pointing to emerging opportunities for further development of applications and modes of interaction.
