The subject disclosure is directed towards a technology by which background application code (e.g., provided by third-party developers) runs on a mobile device in a way that is constrained with respect to resource usage. A resource manager processes a resource reservation request for background code, to determine whether the requested resources meet constraint criteria for that type of background code. If the criteria are met and the resources are available, the resources are reserved, whereby the background code is ensured priority access to its reserved resources. As a result, a properly coded background application that executes within its constraints will not experience glitches or other problems (e.g., unexpected termination) and thereby provide a good user experience.

Constrained execution of background application code on mobile devices

An operating system has an audio system service that can capture all of the streaming audio destined for an output device and make it available for processing. An application can perform the processing upon the captured streaming audio. Any streaming audio that is output by the application and destined for a render device can also be captured for signal processing prior to being mixed with other streaming audio destined for the output device.
