FreeBSD's audio subsystem, sound(4), is one of the fastest out there, but is rather unknown and until recently was largely unmaintained. This talk will go through the various components of sound(4) that make sound possible on FreeBSD, that is:
The generic driver's structure, control flow and interaction with the device drivers.
The audio processing chain.
The user-facing interfaces for interacting with the sound system.
The talk will also mention some notable recent, ongoing and future work across the whole sound system, since my taking over of its development.
I also intend to showcase examples of:
Audio driver and application develpoment on FreeBSD.
FreeBSD being used for music production, and why a musician would consider it instead of other operating systems.
(I may have to leave one or both of these out to keep the talk to the desired duration)
