Wolfgang Draxinger has started developing a new audio sub-system for the Linux kernel became frustrated by ALSA, OSS4, and PulseAudio. This new audio system is called KLANG, the Kernel Level Audio Next Generation.
The developer hopes KLANG will work not only with the Linux kernel but also the FreeBSD kernel. The open-source project is described as offering
“professional grade audio, that means lowest possible latency, latency compensation and bit exact precision at a very low CPU load. KLANG has been designed as a signal routing system, supporting seamless and transparent signal transport between all endpoints. In practice this means that there’s no distinction between hardware and process endpoints. Each endpoint is either a signal source or a sink, allowing for versatile signal routing topologies. All connections are fully latency compensated. A metronome system synchronizes the signal processing to a configurable set of system internal and external clock sources. This greatly simplifies tasks like audio/video synchronization.”
