KVR Audio

I'm online, all background services, using MIDI in and 3.8 ms latency.

It's far better than asio while having all sorts of stuff running. Haven't given it a decent longevity test yet.

Anyway, as it is a part of Windows, maybe it will allow the driver share in the future; eg. maybe we can watch youtube and listen to music, when using
our DAW softwares.

Or maybe you could get a real, multiclient soundcard, and have no such problem with ASIO.

I was so hoping for Wasapi to have a bufferswitch system like ASIO, sadly it seems to be the same as DirectSound, which was ditched for no real reason. Maybe one day Microsoft will release an API that works like ASIO, and with *synced* access to multiple outputs.

3ms on an all-round system with several programs and processes running. Less bugs and hiss than asio4all.

Of course, I'm planning to get an Avid Mbox Mini, but that'd need much more night shifts among the college days... :S

..hiss?? in a software driver?

Yes, as far as my setup is concerned, WASAPI is less prone to pops 'n clicks, and gets slightly less hiss from my line in. Same gain, same hardware.

Yea right, because line-in hardware hiss differs from software driver to software driver. I read about it somewhere, can't remember, called "placebo effect" or something like that...

Maybe that's because this time the line-in is selected by software so the built-in mic is really muted?

Hiss is analog. Then comes the AD converters, after that comes the driver. No way the driver can influence background noise levels...

I'd be really interested in finding out about this hiss, if davidka cares to test it.

Seems like I called on a strange thing, I'll investigate and clear this when I'm back from work.

And yeah, I'm quite the lil'bitch for placebo effects. I can't help thinking that behind a good GUI, theres necessarily a good sound

Must be digital hiss rather than analog hiss...

It was the analog hiss, coming from the line in. It turns out that I was wrong about the gain, as my x86 reaper 3.76 had it's project master 0.3dbs louder than the x64 reaper4 beta.
Barely noticeable, but was enough to amplify my rushing enthusiasm

But, there are really less pops 'n clicks on the same (lowest) latency, when adding more load. For me, that is enough.
So, everything's clear now I hope.

WASAPI. On Win7, it seems better than ASIO. Your thoughts and experiments?
