Abstract AUDIENCE for Pd is a library for audio immersion, sound scene production and auralization. The software enables to work independently the sound scene composition, its acoustic rendering, the encoding of its sound field in a suitable multichannel format, and finally its audition using 2D/3D loudspeaker modes. The system architecture is scalable, many scenes and sound sources can be concurrently processed, and it is possible to interactively place and move objects in the scenes in real time. This paper presents the system architecture, design premisses, and the software implementation. The library structure is explained, as well as how to use it, giving application examples. Ongoing developments and future perspectives conclude the article.

Keywords spatial audio, sound scene orientation, sound encoding, auralization.
