Game Audio in C++ Metro App

Question

I want to add audio to my D3D C++ Metro App/game.  I want to play:

1) Looping background audio PCM, plus

2) Sound Effects - up to 2-3 simultaneous PCM plus

3) VoiceOver - single shot longer voice over PCM

Do I use XAudio2 ??? are there any shortcuts?  I am familiar with DirectSound API. XAudio2 seems somewhat familiar.

Answer 3

Yes, XAudio2 works well, and it was not hard to hook up.

Hooking up SFX was easy.  After reading the docs initially I thought I would also have to hook up streaming from file to play BG audio then I thought about the fact that Metro apps are download-only so I wasn't going to be able to have huge audio assets so I wrote this extension to XAudio2SoundPlayer that allows me to stop and delete an audio voice so I can use one of the voices for BG audio. it goes something like this, if it helps anybody ( I did not see a way to do this with the XAudio2SoundPLayer in the samples)

void XAudio2SoundPlayer::KillSound(size_t index)
{
	StopSound(index);
	m_soundList.erase( m_soundList.begin() + index );
}
