- 1. New Features in DirectSound 5
- ================================
-
- - Addition of DirectSoundCapture APIs. The DirectSoundCapture API
- helps to fill out the existing DirectSound API and allows application
- developers to develop titles using consistent interfaces for both
- audio playback and capture. It also allows titles to be developed
- today that will benefit from new, improved driver models and API
- implementations in the future.
-
- - Playback Notification. DirectSound now provides an interface for specifing
- positional notification along the playback buffers (this also built into
- the new capture API's). To use notify on playback buffers, specify the
- Notify flag on buffer creation and then QueryInterface for the new interface.
- Use this interface to specify positional events which are signaled as the
- playback position passes the specified positions.
-
- 2. Feature Enhancements in DirectSound3D
- ================================
-
- - Hardware Acceleration of 3D buffers. Now DirectSound applications can
- take full advantage of audio cards which support 3D localization of
- hardware accelerated DirectSound buffers.
-
- - MaxDistanceMute to minimize CPU load. This new mode has been added to allow
- sounds to be automatically muted once the 3D position has moved beyond the
- buffers specified MaxDistance. This allows minimal CPU usage for "out of
- range" 3D buffers.
-
- - New Speaker Configurations. Speaker geometry has been added for use with
- the stereo speaker configuration. This has been added to allow application
- to set the angle of the speakers with respect to the listeners. This is
- information is useful for some hardware 3D algorithms to improve the quality
- of the 3D effect.
