M-Audio Duo/half duplex

Rain Mooder wrote on 2/5/2004, 9:56 PM
I have an m-audio duo and it can be adjusted to record 96khz/24bit or
play it back but not both at the same time. If I use the ASIO driver I have
to pick which it is that I am going to do in a little driver window. This is
kind of tedious. Does anyone have a work-around for running 96khz+24bit
with Vegas or indeed any program using the Duo

Yeah, It's called "get a new sound card." Echo cards will do it. Is there a reason you need to record at 24/96? I will bet you won't be able to tell the difference between 24/48 and 24/96 except for all the additional hard drive space you have left over.

I agree with Red. Dump the M-audio and get an Echo or something similar. M-audio is notorious for driver problems and they are extremely unfriendly to Sony/Sonic Foundry. As I've said in other posts, I avoid their products on prinicple alone. There's lots of good products out there.

You can't use a half-duplex ASIO device in Vegas 4 in record only mode. You MUST have a playback port at all times in Vegas.

Unlikely we will be supporting something like this. I will have a look, but this is just not a reasonable approach to hardware/driver design.

Bummer. Yeah, I need the 24bit part pretty badly. I'm recording
things with very high dynamic ranges so that I use
compression/expansion later. I also need to have preamps
and run it off a laptop. Not many options unless I go to an
Edirol UA-1000 but why do that when the Presonus Firepod is
coming out in March. Uggh..And I need it working by Tuessday...

Off to go find an old copy of Cool Edit I guess.

As I mentioned, why don't you just drop the sampling rate down to 48Khz, so the card will function in full duplex mode? The sampling frequency has nothing to do with the dynamics range. Recording at 96Khz sampling frequency, only means that you can record sounds that have frequencies up to 48Khz. Most speakers will not even reproduce frequencies this high, yet alone the human hearing does not extend that far. For your Tuesday solution, drop down to 24bit/48Khz and you'll be fine.

The M-Audio duo will only operate at 24bits IF it is also sampling at
96khz or 88khz.

Actually, I guess you guys are right. Maybe it will do 48/24...

Now the problem is that when I use the WDM drivers all I get
is static crashes and spikes in the audio. I can't see the ASIO
driver in Vegas... How do I get the duo's ASIO driver to appear in
Vegas?
