I especially want to recommend the Realtime Audio vs. Linux 2.6 paper by Lee Revell to everyone who has an interest in low latency audio processing on Linux. At the conference, Lee gave an excellent presentation on the topic and the recent work that went on in the 2.6 series of the Linux kernels. He also presents curiosities like why benchmark optimized video card drivers may get into the way of realtime audio processing.
Amongst other things at the Linux Audio Conference i recently blogged about, i also found the presentation on Ontological Processing of Sound Resources particularly interesting. With the growth of audio material collections, searches confined to the natural hierarchy enforced by file systems become increasingly ineffective. An alternative browsing approach can be based on tagging of audio material (the paper examines this in the context of instrument types), automatic deduction of tags and inference mechanisms on these tags. This is suitable to support user queries that contain music/instrument characteristics rather than arbitrary names.
