Is ASIO necessary? - Page 3

post #31 of 37
I see, it looks like what I was going by was oversimplified......but is there any specific advantage to using the combination of an ASIO API dll with an "ASIO Kernel Mode Module" driver, versus an ASIO API dll combined with a "WDM Adapter Driver Mini-Port" driver?

Seems that both would bypass any resampling/kmixer issues, and that is my main reason for using ASIO.

What's an "AEC (Vendor-supplied)" in the top diagram?

EDIT: I Googled that and found it might refer to "Acoustical Echo Cancellation"......and if that's the case, not a consideration for our discussion here!

I have the program TheaterTek which I use to watch DVDs. Not sure if it supports ASIO though. I will have to check and see.

Yeah fetal I was wondering if everything can be done through ASIO by switching some sort of driver setting on the Prelude but I guess non exists.... as long as the player I'm using to play whatever movie, music, is set to an ASIO plug-in (and plug-in set to Prelude) the card would be doing it's job?

the way i've been using asio is just setting winamp to use an asio plugin, it sounds different than using directsound, is there another way for prelude to ALWAYS use asio no matter what or is this not possible?

Prelude X-Fi seems to support ASIO 2.0 so ASIO mode shouldn't be an issue there. If you like to try playback through native ASIO then just try the NI TRAKTOR BeatPort Player listed in my sig.
Rule is that if your card don't support ASIO then you need the Asio4All (or asio2ks or asiox or ASIO MME/DirectX from Steinberg or some other ASIO wrapper if there are more to list) being installed 1st to get that ASIO plug-in for your software working.

So, it's software depent rather than hardware depent matter if you can switch into ASIO mode or not. Most media players just don't support ASIO at all (CT media source, WMP/WMP Alternative and quicktime/QT Alternative as for an example) or some of those needs a special ASIO output plug-in for this (winamp, media monkey and foobar as for an example). There are few media players with native support for ASIO (NI BeatPort player/sync, maybe j. River Jukebox and media center too as for an example).

When just playback audio then there isn't (much) difference between those two but when you record there may be some differences but, that can be partly hardware/driver related matter (as for an example with Creative SB/X-Fi cards in WDM/KS (and ASIO wrapper) mode, you can select only one stereo (two mono) input source(s) at once becayse of you need to use CT/system Mixer recording source selector for to select the source (i.e. one mic or Line source) when by using ASIO, you can select as many input ports as your card hardware supports to be selectable at once as mono or stereo because you select I/O's in your recording software instead of through CT/system Mixer (i.e. mic + Line 1 + Line 2 with Platinum cards)).

Fetalgoat, any update on native ASIO support for TheaterTek?
post #37 of 37
I'm not sure yet. Natively it's not supported but there might be a way to get it working using something like FFDshow perhaps.

If the auzen has native DD encoding I wonder if it decodes DD over analog or if it passes it through Kmixer. There are two separate audio options in theatertek for the prelude, one is Auzen Audio and the other is Directsound: Auzen Audio. I'm not sure what the first could be.
