The waveform audio API provides an application exact control over waveform audio input/output devices. It also supports the hardware audio mixer API. In addition to providing volume control, the waveform audio API provides routing services to manage audio lines on your device for playing or recording. Routing services require specific hardware device and driver support. The mixer architecture allows several audio source lines to be mapped to a single destination audio line.
