Demo setup for AM

Well, this would be an interesting bug, if it does turn out to be in the software. I just installed two ASIO versions last night. Downloaded Ver 0.90.93 from the link on this site, loaded it in, authorized it & it’s working right out of the box. On both of these installs I can open the tilt parameters, so long as HPF isn’t off, so I thought that might be what was stopping you.

I thought it might be a sensitivity to what card was plugged in (I’m using the Audiophile 192). Don’t have anything else here to test that idea, at least not with the ASIO version, though I also have the standard BBP here, and it does the same thing, both with the 192 card and through the computer’s onboard audio. Seems that would tend to point to something other than the ASIO version, maybe?

That probably doesn’t help you much, but from here it doesn’t look like a bug in the software.

[quote author=”AM Robert”]Thanks RJ, That does help allot because I now know that the AM related features do still come with the paid ASIO version. I could not get anybody in corporate HQ to give me an answer so Im guessing with your paid order you get a contact number or email address you can call for support if needed?[/quote]
I just told you that it DOES come with it, and that if it’s not working then it’s a bug… or maybe even user error. If the software didn’t have the features, the buttons wouldn’t be included grayed out just to tease the customer. You don’t really think that, do you?

OK, I’m going to try this right now.

Ok, here’s my test setup 🙂

Reaper… uses a 64bit audio engine so there’s no qualms about quality there. 🙂 Setup like so:
http://stashbox.org/820805/03122010-074 … icense.png

And track 1 of that is outputting through ReaRoute which is Reaper’s own routing engine which supports other applications (it also does rewire, osc, etc).

Breakaway ASIO Settings:

Breakaway ASIO I/O Config:
http://stashbox.org/820808/03122010-074 … r-ASIO.png
As you can see we’re getting our inputs from, and outputting to, ReaRoute 1/2.

Breakaway ASIO Calibration:

Make a mental note that the reference output level here is -6 dBFS.

All to NTSC spec… then, the audio routes back through ReaRoute and I’m monitoring & recording it in Reaper, on track #2.

Saved track #2 as 32bit float, still VERY high quality audio. Let’s have a look at that in Adobe Audition v1.5:

It looks like asymmetric clipping has happened. Let’s have a look at the statistics 🙂
http://stashbox.org/820813/03122010-074 … istics.png
Notice… the peak amplitudes are:
-3.06 dB
-2.89 dB
for the left & right channel respectively. What that means is there was 150% above -6 dB somewhere within that recording. You can see in the screenshot that it happened a LOT too. 🙂

Let’s also check out the spectral content:
http://stashbox.org/820817/03122010-075 … dition.png
As you can see, the signal is completely band-limited just before 10kHz.

Conclusions:

• It it absolutely doing asymmetrical clipping properly.
• It is absolutely band limiting using the low-pass filtering correctly.
• The Calibration dialog has a bug where some of the controls are "paginated" below the window and are unusable, including the low-pass filter width & shape controls which are useful in AM broadcasting.

You’re absolutely right about the gui. I apologize for the inconvenience, and thank you very much for the help in tracking it down, i will make sure it’s in perfect working order for 0.90.94.
