1. Object Design: Audio Subsystem
Karim Morsy
Audio Team

2. Overview Implementation language and Documentation Object Model
Reuse of algorithms and adaption of existing open source technologies
Trade-Offs

3. Implementation language and Documentation
C, C++, Objective C
Doxygen

5. Existing Open Source Solution

6. VSOExtendedOpenAL Conventions for writing extensions to OAL
Parameterized C functions
void alListenerf( ALenum param, ALfloat value )

7. Parameter Extensions VSO_TIMEPITCH VSO_PITCHSHIFT VSO_REVERB
Reverb Presets: SMALL_ROOM,LARGE_ROOM, CATHEDRAL,LARGE_HALL, etc..

8. Extending Listener Functionality

9. Audio Subsystem Layers (closed architecture)

11. Trade-Offs Constraint: No way to find the current time stamp
We have running subsystem with a variety of extra features
Highly efficient and robust
