WASAPI Support #210

Closed GoogleCodeExporter closed 9 years ago

There is lot of Latency with Demul and Xaudio2 is a high latency API, thus 
would like WASAPI Exclusive/Shared to be added

WASAPI Exclusive basically lets Demul talk directly to your sound card without 
any interference

"and Xaudio2 is a high latency API"
maybe, cant say, because Demul doesn't uses Xaudio.

I don't think moving from one Microsoft exclusive API to another is really good 
idea, if and then we decide to change sound output API to some another it 
probably will be multiplatform one.

Is demul still using Directsound? which is a deprecated API and as downgraded 
performance/High Latency on Windows Vista/7/8.

Difference between Dsound, Xaudio2 and WASAPI.

Demul > Dsound > Emulation Layer > WASAPI > Audio Output (Highest Latency) 
Demul > Xaudio 2 > WASAPI > Audio Output  
Demul > WASAPI > Audio Output     (Lowest Latency)

if its not clear from previous message - in my/our opinion doesn't really 
matters what latency or performance is.
in Demul's case they are ~ small and can be ignored.

as was already said - if/when sound output API/library will be changed to some 
another one, it will be chosen taken from portability and usability.
