Best way to play two audio files simultaneously in Windows Phone 8

Question

Currently looking into how I can go about playing two mp3 or aac format files at the same time in Windows Phone 8.

At the moment I am using the XNA SoundEffect class

Answer 1

Solution : Hi, I was developing a WP8 App and i needed multiple sounds to play simultaneously, i used the XNA framwork. here is the link

and then play ur sound files like this...

SoundEffect Sound = SoundEffect.FromStream(Application.GetResourceStream(new Uri("Assets/Sounds/wav/sound.wav", UriKind.Relative)).Stream);
Sound.Play();

For looping...

SoundEffectInstance Sound = SoundEffect.FromStream(Application.GetResourceStream(new Uri("Assets/Sounds/wav/sound.wav", UriKind.Relative)).Stream).CreateInstance();
Sound.IsLooped = true;
Sound.Play();

Note: the files must be in ".wav" (PCM, 8 or 16-bit, 8KHz to 48KHz, mono or stereo) format

Answer 2

You could try to do it through MediaFoundation.MediaEngine (see "Supported Microsoft Media Foundation APIs for Windows Phone 8" for guidelines on how to initialize it correctly on WP8). In SharpDX there is a Win8 samples MediaPlayerApp that could be used as a starting point to play only audio (remove all the d3d part and apply guidelines for WP8). There is also a usage of it in MonoGame MediaPlayer class.

Concerning playing multiple WAV with SharpDX at the same time, it is perfectly possible with XAudio2, and SharpDX doesn't have any limitation concerning XAudio2.

There is only a huge concern about the WP8 CLR Garbarge collector that seems to block all native threads when it is collecting, including native audio threads like XAudio2, and that could cause audio stuttering. There is nothing we can do about this, as this is an issue with the OS and the scheduling of threads with .NET.

I have also some doubt about the ability of WP8 to decode two MP3 in realtime... Let us know if you have some results.
