Deletion of XAudio2

Comment: The book ''Ultimate Game Programming with DirectX'' discusses XAudio2 in depth on pages 283-289, more than a passing mention. There is an 8-part tutorial on Xaudio2 at http://www.win32developer.com/tutorial.shtm win32developer.com. I do not share the nom's deep cynicism of the trade press and regard both of these as independent reliable sources. In addition, there are independent reliable sources, in less depth, that could also be useful, such as the book http://books.google.com/books?id=ULfp5GcVTukC&pg=PA260&lpg=PA260&dq=xaudio+wikipedia&source=bl&ots=MXMvCSNGkw&sig=npVsvJtUGhsRtRnSYcnZdKTju80&hl=en&sa=X&ei=fN92UrfzJavy2gWrz4HoAw&ved=0CE8Q6AEwBA#v=onepage&q=xaudio%20wikipedia&f=false  Professional XNA Programming: Building Games for Xbox 360 and Windows with XNA Game Studio 2.0, which has about half a page on that discusses it and the two articles at http://www.maximumpc.com/article/time_directx_10_charting_future_windows_3d_graphics_and_audio at Maximum PC and http://arstechnica.com/gaming/2007/08/alook-at-directx10-1-and-why-it-wont-make-you-trash-your-video-card/ Ars Technica which cover the XAudio2 debut. The existence of multiple in-depth reliable sources shows notability, per . While the article could be developed in greater depth, it has no major problems. In particular, the article ''does'' assert the notability of XAudio2 as the successor to DirectSound. I don't see any evidence of promotion or non-neutrality in the article. The article has no insurmountable problems, per . A notable topic and an article with surmountable problems suggests keeping the article
