| The goal of this master thesis is the design and prototype implementation of a sound subsystem for HelenOS. The subsystem consists of a sound device driver layer (for PCM devices), simple sound server layer for the abstraction of the features of the physical devices (independence and indirection of clients and devices, future possibility to do format conversions and software mixing, etc.) and client API for end applications.
The design and prototype implementation respects the microkernel architecture of HelenOS and is inspired by the features of state-of-the-art sound subsystems (PulseAudio/ALSA, JACK, Core Audio, DirectSound/UAA). The functionality of the prototype implementation is demonstrated by a basic Sound Blaster 16 driver and a driver for USB audio class devices. |
