XAudio2

<h2 id="features">Features</h2>
XAudio2 provides mixing and <a href="/facts/Audio_signal_processing/HXvBpspA">signal processing</a> for high-level audio APIs such as <a href="/facts/Cross-platform_Audio_Creation_Tool/WHJYzhnu">XACT</a> and as well provides the programmer with high-level functions related to <a href="/facts/3D_audio_effect/8McKzRPU">spatial processing</a>.<a class="footnote-ref" id="fnref:9" href="#fn:9">9</a>
XAudio2 <a href="/facts/Abstraction_(computer_science)/hAnxmJle">abstracts</a> audio generation by separating sound data from "voice", allowing each voice to be filtered by programmable <a href="/facts/Digital_signal_processing/PEG7azr8">digital signal processing</a> and effects processing functions. Voices can be "submixed" together into a single stream.
XAudio2 can natively decompress <a href="/facts/XMA_(audio_format)/s5zePro7">XMA</a> on the Xbox 360, <a href="/facts/Windows_Media_Audio/s5zePro7">xWMA</a> on Windows 10, and various <a href="/facts/ADPCM/Q6cFrNUb">ADPCM</a> codecs on both platforms. XAudio2 2.8 supports Windows Store App development and can be used in C++/DirectX apps.<a class="footnote-ref" id="fnref:10" href="#fn:10">10</a>
