New Paper on Parallel Computing and Network Audio

The Journal of the Audio Engineering Society (JAES) just released a special issue on network audio. It features collaborative research work on low-latency audio processing by UC Berkeley’s Parallel Computing Laboratory entitled “A Multicore Operating System with QoS Guarantees for Network Audio Applications” :

While network-based mechanisms are important to enable deterministic transport of audio data from transmitter to receiver, there is an equally important role played by the operating systems that reside in audio devices of all sizes. The applications that receive and transmit audio are dependent on these operating systems to allocate processor and input/output resources. Authors Colmenares, Peters, Eads, Saxton, Jacquez, Kubiatowitz, and Wessel have presented Tessellation, an experimental operating system tailored to multicore processors, and have demonstrated how it enables network applications to meet their stringent time requirements.

The article can be found here. It will also appear in an upcoming textbook on parallel computing.

New Paper on SpatDIF

The latest issue of the Computer Music Journal (MIT Press) includes an article on the Spatial Sound Description Interchange Format (SpatDIF) by Trond Lossius, Jan Schacher, and myself, entitled “The Spatial Sound Description Interchange Format: Principles, Specification, and Examples”.


SpatDIF, the Spatial Sound Description Interchange Format, is an ongoing collaborative effort offering a semantic and syntactic specification for storing and transmitting spatial audio scene descriptions. The SpatDIF core is a lightweight minimal solution providing the most essential set of descriptors for spatial sound scenes. Additional descriptors are introduced as extensions, expanding the namespace and scope with respect to authoring, scene description, rendering, and reproduction of spatial sound. A general overview presents the principles informing the specification, as well as the structure and the terminology of the SpatDIF syntax. Two use cases exemplify SpatDIF’s potential for pre-composed pieces as well as interactive installations, and several prototype implementations that have been developed show its real-life utility.

Best paper award at SMC 2012

Today Trond LossiusJan C. Schacher, and me received the Best Paper Award for “SpatDIF: Principles, Specification, and Examples” at the 9th Sound and Music Computing Conference.


This paper presents the current state of our long-term effort in creating a community-driven interchange format for spatial audio scenes. More on

We are now invited to submit a revised and expanded version for publication in The Computer Music Journal (MIT Press).


I am similarly excited that the paper “An Automated Testing Suite for Computer Music Environments” I wrote together with Trond Lossius and Timothy Place was also nominated for Best Paper.
