Not sure about your question but...

I run windows XP with an echo audio Darla 24 card, and I cannot record into Vegas 3.0 at 24 bit resolution. I have asked their tech support repeatedly when their crappy WDM drivers will no longer cripple my card to 16 bit under my favorite app (vegas 3) and this was the response:

"We do not have a date for these drivers at this time. They will not be on version 6.1 set to be out shortly but they should be on the following driver. We will pass on your request to our driver engineers.

Thank you,

Echo Technical Support

Mind you this response comes 3 months after they told me 24 bits would be enabled within a few weeks for vegas. (that was 3 months ago)

I was so upset I went out and got myself a delta 44 card. boy, that was a big mistake. 24 bit recording worked with their WDM drivers, but it sounded like a trainwreck under XP compared to my Darla card. So, back to square 1. I'm considering the new Motu 828 firewire or the event EZ bus, any reccomendations? RIff out

I've tried the MOTU 828 on Win2K, VA2 last year on my Sony PCG-SR17K laptop. There's even a picture of this computer on the 828's box. Well, the Windows drivers didn't work. Maybe they work on Win98, and maybe they have fixed them by now, but I was not convinced. I also tried the 828 on a new iBook, and it worked there, so it wasn't a hardware problem (however, their recording application for the Mac crashed a lot...).

I swapped the 828 for a slightly more expensive RME Digiface with external converter, and that system has been running very well (although I haven't actually checked whether 24 bits are recorded properly in Vegas - should do that sometime). I recommend it. They have CardBus versions as well as PCI. Sound is very good, and the system has a fantastic simple digital mixing desk built into the hardware (no CPU load on the PC), which is great for headphone monitor mixes.

something tells me this won't be the last post on this thread, but here you go:

"If you are using WDM drivers with your Sound Card under Windows 2000, and you are going through the kmixer as Vegas does (and which any software that opens the card as a standard wave device does), 16-bit recording is currently the maximum that will be recorded, even if 24-bit is reported.

Microsoft XP and ME do not have this behavior.

There is no official word from Microsoft regarding a fix or service pack to address this issue."

Hmm...

Something tells me this will never be corrected in Win2k...
It's a good thing that moving to XP is not an issue for me.
I don't think that everyone will be so understanding, especially if Sonic Foundry does not supply some sort of "advanced i/o system" (wdm or otherwise) to bypass the kmixer problem with future updates to VV3.
Pump.

I just recently upgraded to VV3 from Audio 2.0h and recorded two tracks at 24 bit.

My setup is as follows:
win2k
Delta 1010
1.4 gig AMD tbird
768 MB Ram
7200 rpm ata/dma 133 drives
etc (just recently built machine and it really smokes!)

My problem:
I tried burning a CD of a mix I made of these tracks and it failed every time. I was curious so I tried playing the .wav file outside of VV3 and it was "unrecognized". So, finally, I opened the mixed 24 bit wav file in Sound Forge 5. I converted it to 16 bit and THEN everything worked great. I could tell a difference in recording at 16 bit and 24 bit and would like to continue to use 24 bit but will I be able to create CDs at 24 bit?

PS. I tried using the built in CD Burner tools in VV3 and it failed also. I was only successful using Adaptec w/ a 16 bit file. The error I was receiving was a "over buffer error". Bufferring was at 100% the whole time when trying to burn. I have tons of RAM and HD space so resources shouldn't have been an issue. Lastly, are there any setting regarding the CD-writer (Mine is a HP-9500 12X burner).

Many thanks,

if you are trying to put a 24 bit audio file onto an audio CD, then you are wasting your time :)

16-bit 44.1KHz Stereo

that is the Red book/CD-DA standard:
