I rather not share because I am not sure if I can. But this application creates experiments where timing of events and sounds is crucial. Something like psychological or medical studies that measure responsiveness. When I said to use something else, I meant to still use WASAPI exclusive mode for playback but link a converter and a mixer (Audio Resampler DSP) to take care of the pre-processing. Obviously I don't know much about this and that's why I am asking so many questions... Nicole

Peter, So you are basically telling me that there is no mixing function in exclusive mode and I will have to write it. Well, that is always a possibility... Would it make sense to use something else to do the mixing for me and then do the playback through exclusive mode or would that really mess up the latency? Here is really the problem: I have an application in C++ that is currently running on both Vista and XP. Because of the nature of this app I need low latency. In XP the latency was fine, no problems (using DirectSound) but in Vista because of the architecture there was something like 50ms difference. I need to get rid of this difference and this run the same way on Vista as on XP. The ideal thing would be to use something that's already out there and just rewrite the app so it stays the same for XP and Vista. I haven't found any easy way of doing this. I don't want extra apps sitting on top op WASAPI in Vista to make it even slower than it is... So my other option is to just make a different version for Vista. Would you recommend using WASAPI or is there onything else that might be simpler to use? Sorry for so many questions, I am very new to all of this and I am just doing some research before I make a decision about what to do. Thanks, Nicole

yes that is true. Do you know how to do sound mixing using WASAPI? nicole

Hi, I am trying to get latency

Peter, how do you do sound mixing using WASAPI in exclusive mode? I am trying to use Visual Studio to do some C++ audio programming... Bacause Vista is so great in handling sound I need to get
