I can’t get my Echo card to work unless it is in ASIO mode. Using the Echo Indigo DJx expresscard I get this error no matter what core audio sample rate I set the Echo to.
Core 1: unable to open "Virtual out 1-2" for output at 44100 hz, 2 channels, 16 bits. Device does not support requested format, or sound device is busy.
I tried different virtual outs, restarted the computer, made sure nothing else is running that would be playing audio.
If I look at the advanced tab in the windows playback properties for Virtual Out 1-2 (and the other virtual outs) the format is greyed out (set using the Indigo DJx Console) and is set to 2 channel, 24 bits, 44100 Hz (Studio Quality)
My guess is the 24 bits is the problem? I don’t see any options in my Echo control panel to change to 16 bits. Thanks.
It *could* be that the driver doesn’t support 16-bit output, but it would be the absolutely first time I have seen a sound card that doesn’t. Did you try 48000 Hz as well?
If the bit depth is the problem I could always add 24-bit output support. But, the big question is why ASIO causes such problems, it’s generally very stable. Do I remember correctly that you’re on Vista?

Actually, Leif, Asio works fine. Yes, I’m on Vista 64-bit. I tried all the options available, 48khz too, I just thought the KS driver should work too, not just Asio.
Here’s the description of what I have, maybe 24-bit is the only supported bit depth?
Two reasons:
1 – The Breakaway core (a common building block of all Breakaway products except Breakaway RTA) did not support it. Breakaway uses 32-bit math, split as 16 bits for audio and 16 bits of headroom. However, it now has a mode where it can use 24 bits for audio and 8 bits of headroom (still +48dB), so this reason doesn’t exist any more.
2 – Simplicity vs Benefit: Generally, sound card drivers support 16-bit and not 24-bit, and the benefit of 24-bit is very small compared to the compatibility headache. Also, all Breakaway versions (even the $29 one) uses an advanced ultrasonic noise dithering algorithm for the output, which to me sounds perfectly clean even turning the volume down to -40dB.
I may do 24-bit support in the future though, but my to-do list spans volumes already, so please don’t hold your breath! I’d hate to lose a good customer 😉.
Best,
///LeifLeif, my Echo specs say it supports GSIF (32-bit only), would this help me any, or better yet, could you support that? I have no idea what GSIF is. I think the ks mode is only 24-bit for the Echo? But Asio is ok with 16-bit? I don’t understand it.
GSIF is similar to ASIO.
Breakaway’s ASIO subsystem actually supports outputting in both 16 and 32-bit integer format, depending on what the ASIO driver requests.

Awesome, then don’t worry about the 24-bit for the wdm driver, it sounds great in Asio. I just thought it would work with the kernel streaming driver mode also. What about running the stereo mic/line input from the internal soundcard on the laptop through BDJ also while playing OtsAV so I could process the mic input? Can I use the breakaway pipeline configuration? Thanks again.
Wouldn’t work very well, as the microphone would then end up mixed with one of the decks. There’s no easy solution to this, which is why I kept mic processing out of Breakaway DJ completely.
The ultimate solution would be to run Breakaway Live on a separate machine, connected AFTER the mixer. That way, everything would be processed together, including the microphone.

Actually… the testing and comparisons we did were gained up nearly 80db. Breakaway’s dithering compared VERY favorably to all of the other top high-end dithering & noise-shaping algorithms. There was only 1 or 2 others that I would consider had as low a dithering noise level as Breakaway’s, and the design of Breakaway’s is 100% sound (pun intended), so it’s absolutely doing its job.If you wonder what the 1-2 others were that I thought came out the best… it was Izotope’s MBit+, and the shaped TPDF from Voxengo Elephant 3. Consolation prize on noise level going to Apogee UV22 HR, but overall consolation prize going to POW-r 2 simply because it sounds more transparent and has way less potential to create a "whine" sound if there’s aliasing after it.

A few soundcards/converters don’t support kernel streaming actually. It’s rare, but happens. My Apogees for instance… no kernel streaming with the default or Apogee-supplied drivers.[quote author=”Leif”]Two reasons:

Best,
///Leif[/quote]Given this outstanding response, would I do best to switch the 24-bit feature off on my soundcard? Or will it not affect things either way?
Thanks.

Leif, all I’m asking for is 1 line input that can be mixed with the signal 🙂 I would like to be able to play a turntable or other input from an external mixer through breakaway along with whatever audio program I’m running on the laptop. It seems excessive to have to have a whole other computer in my setup just to do this, wouldn’t it just be mixing the signal prior to processing it with BDJ? It seems it shouldn’t be that hard, but I am not doing your work! Just run a virtual patch cable from the input to the BDJ interface?
I’m starting to realize then need for BDJ PRO, which should support line inputs, four decks, and TCV. Will look into it 🙂.
