Abstract
An application programming interface (API), implemented on a general-purpose host processor, receives functions calls from an application to control the play of an audio file. The API translates the function calls into host-to-board messages and transmits the host-to-board messages to an audio task, implemented on a digital signal processor. The audio task plays the audio file based on the host-to-board messages received from the API at a higher priority than one or more other audio files. The API and audio task allow the application to select a Microsoft®-standard Wave file for play at a higher priority than other Wave files. By using the API, the application has control of the number of times the file is played back and when playing stops. The application gets notification of playback complete from the audio task via the API.
