This is the price you pay to get maximum control. However the flipside is that you will need to provide your own logic to mix sounds, track positions, and scheduling. It does not get much lower level than this. While in XAudio2 you will deal with sound source objects (PC audio data) which you can instruct to play or loop through different mixer configurations, WASAPI allows you to receive notifications when capture data is available or render data is needed. In terms of architecture, WASAPI is a lower level API and will provide the low level access to the hardware and audio engine. XAudio2 is purposely built to provide signal processing and mixing foundation for developing high performance audio engines for games. Leaving aside media APIs that are exposed as part of WinRT, there are really two sets of APIs available to Windows apps for low level audio access–WASAPI and XAudio2. Thus, with some modifications it will be possible to build a Windows Phone app. While the examples and text are specifically meant for Windows, the APIs used will all compile under Windows Phone projects. This post describes how to write Windows Store applications using WASAPI. The API is based on COM, which means either writing your app entirely in C++or writing a wrapper Windows Runtime Component that can be accessed from Windows apps written in other languages. Fortunately, Windows has a low level audio access component called WASAPI–the Windows Audio Session API–which enables organized access to low level audio functionality for desktop applications, Windows Store apps, and Windows Phone apps alike. There are, however, some scenarios where you want to render or capture sample by sample. These APIs handle all complexities like audio format conversion, different sample rates, and different hardware capabilities. Windows Runtime APIs expose many functions to deal with playing and recording audio for both Windows Store apps and Windows Phone apps (starting with Windows Phone 8).
