OpenAirLib: A JavaScript Library for the Acoustics of Spaces

Document Thumbnail

The possibilities for creating online sonic art and virtual acoustic environments have been increased by the introduction of audio Application Programming Interfaces, libraries, and online resources of acoustic impulse responses (which encapsulate the acoustics of real or imaginary spaces.) This paper presents the OpenAirLib JavaScript library that extends the capabilities of the World Wide Web Consortium Web Audio API, facilitating the incorporation of three-dimensional acoustics of spaces into web audio projects. It enables first-order ambisonic material from the Open Acoustic Impulse Response Library (OpenAIR) website to superimpose the acoustics of one space onto synthesized or recorded material from another space. An example is then described which uses these technologies to produce instances of generative online sonic art from OpenAIR data.
