Yes, absolutely, but it'd be good to make this measurement easy to repeat by anybody interested. To do that, let's just loop the audio output back into the audio input. The user will have to provide a loopback cable (or, worst case, put his mike right up to the speaker, and allow for a tiny bit of extra latency from that).
But if all you are interested in is the relative latency changes, then any additional latency effects should not matter as long as that latency added is constant.
Right.
What is being checked is that the latency of wine+OpenAL is not noticeably greater than the current wine+ALSA implementation (that is, OpenAL has a latency that is at worst equal to ALSA as used by wine to within a certain tolerance for error).
Yes. Ideally we'd also run the app with other combinations as well (say, wine+OSS, or XP+ASIO, or Windows 7) to make sure we're not aiming too low. - Dan
