ARTA calibration help

[augerpro]

I just downloaded ARTA to check and was going through the calibration but I'm having a problem. This is on a laptop using the MAudio Firewire 410. At step 1.5.2 for calibrating the inputs, I have the left output looped back to the left input but when I run the generator the bar graph at the bottom doesn't show anything, so I don't know if the input is clipping. The soundcard shows both and input and output signal, confirmed the output with a voltmeter, and doing the same loopback in SE works as expected. Anyone know why the graph isn't showing anything?

When I used ARTA for the first time I had to double check settings and go through my setup a few times before I had everything setup right - both the soundcard settings (turning on "Mic Boost" for instance) and the physical setup. There was a little bit of a learning curve, but not too rough, not nearly as tough as Sound Easy, for instance.

Now, I love it, and no more headaches. It's fast and easy to use, once it's setup Once I figured ARTA out, I gave up trying to get good measurements in LspCAD or Speaker Workshop, because ARTA seemed so much more easy and reliable. The features like the automatic measurement splicing for low + high freqs. and the distortion testing are wonderful to have available in a free version.

Hey Brandon,

I think, if you're running XP, you need the WDM driver installed and you need to check the 'Extensible' box in ARTA's sound card setup.

And this WDM driver would have been included with the soundcard drivers probably?

Is your laptop's built in sound card disabled in the BIOS?

What happens if you try to do a measurement w/o calibration?

I tried to use an external M-Audio USB soundcard (Transit?) and I got inconsistent results with each program I tried. I bought the cheapest SB Audigy 4 soundcard I could find, and it's working great with all the programs I've tried so far. I had problems with a few different sound cards, I tried a bunch of different drivers too - so many headaches, but now with the cheap new card, it just works - I was about to pull my hair out before that

Should have been, yeah. I don't think ARTA would have been able to make the card put out any voltage without it. Do you have the extensible box checked? I've heard others say that made a difference but I dunno.
