Is ASIO necessary? - Page 2

post #16 of 37
I can't find a difference between regular USB output and ASIO output.

huh, USB is hardware level, ASIO is software level

do you mean you don't hear difference between USB and SPDIF?

or do you mean between ASIO and DS?

With my 0404 I didn't hear any difference between DS, KS, and ASIO4ALL. Once I figured out I didn't need ASIO4ALL and got it configured through the E-mu drivers it sounded a little better. So that's how I left it, but there's not much difference between the various options.

this doesn't make sense. Did you somehow confige asio4all to the emu drivers? what gave you a little better sound?

for those who have used the prelude... how do you enable asio?

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?

I have the asio plugin in foobar set to output Auzen ASIO.

I'm not sure how one would go about passing everything else through to ASIO though (which is what I take it you mean). For youtube videos, games etc it doesn't really matter than much to me.

What I meant is:

I hear no difference between:
- Just plugging in the USB cable of my Mini-DAC or Cantate and outputting the default stuff; and
- Going through all the trouble with setting up ASIO, as a result being able to output only one thing at a time

Therefore, since I don't hear a difference, I prefer regular plug-'n-play USB sound.

ASIO is necessary!

Here's an example what it means:



clear/clean sound even @ 1,5ms .. even surfing the web ... downloading files and opening/closing program windows ... etc. while listening music.

Though even this is not native ASIO E-MU programmed for their USB audio devices (it's a WDM/KS wrapper just like the famous Asio4All is (just implemented maybe differently)).

I use Media Player Classic for watching DVD's and Movies, is there any way to get my X-Fi Prelude's ASIO to work for this or would you recommend a different program for watching movies?

I like Media Player Classic for it's minimalistic appeal, I'd rather avoid anything that adds a ton of bloatware.

No, you can't use ASIO or WDM/KS (Kernel Streaming) with those generic media players.

I don't know any other media player but J River Media Center which support ASIO ?

You sure about that?

Something seems odd about what is in that "Preferences" window under "Audio Device"........"ASIO E-MU 0404 | USB" is exactly what is displayed when the native E-MU ASIO driver is selected in Foobar output configuration and in all of my other apps that are ASIO-capable.

Hmm... not 100% sure but as E-MU tells in their driver -





BTW, do you know any USB audio device with native ASIO ?

no its not "necessary", if it works for you, use it, else dont bother.

I think the 0404 USB implementation is about as native as it gets, based on on what I know so far......though I am far from an expert on OS architecture and its relationship to audio devices.

My understanding of the differences between the various options comes from this page (and maybe it's wrong, but it certainly make sense to me!):

ST Audio Knowledge Base

Basically, an API must always sit between the playback application and the driver kernel module.....that can be MME, DS, or ASIO, or some as yet unconceived method. Any of those will still use the same driver kernel module, it's just a question of what is being used in the chain above it to interface with the audio application.

From that article, I've always presumed that because I want to avoid any addtional resampling or DSP between Foobar and the 0404 USB, using the supplied E-MU ASIO driver was the most direct and certain way of achieving that goal. I've read of resampling and kmixer problems that are inherent with Wave/MME and possibly in DS, but not with ASIO. So it's more that ASIO definitely will not do what DS may or may not do that makes me opt for ASIO. Does that make sense?

It does seem from that article that KS is probably the ideal situation, but I've not had good luck with getting Foobar 0.8.3 to work well with the 0404 USB (the pause-pause issue, plus hang ups make me go back to ASIO, which just seems to work!)

Here are three pictures which might explain something:

1. WDM Overview:




2. Driver Componentry on Win2k/WDM:



("Native ASIO")



3. Simplified Driver Componentry:



("ASIO as WDM/KS wrapper")
