Question

Help! Mapping Input #1 to both L & R, all stereo becomes mono

Hi, I'm hoping an Adobe Audition expert can help me figure out what happened here...my PreSonus AudioBox iTwo used to map correctly, Microphone 1 to Adobe Audition Left, Microphone 2 to Adobe Audition Right. Last week I noticed somehow it had switched so that the input from Microphone 1 maps to both Left & Right, but Audition doesn't see or doesn't use signal from Microphone 2. (This setup prevents me from recording a two-voice podcast, or digitizing audio that was in stereo). By switching MME to ASIO I was able to record both L & R, but I'd rather get it back to how it used to work; once in ASIO mode the computer wouldn't play the audio back unless I switched back to MME. I tried other sound-recording programs, which had no problem identifying the two channels from this PreSonus; I tried another audio interface (Motu Ultralite mk3), which delivered L & R properly to Audition with MME selected. But the way I've used it for years no longer works.

Not sure whether it's significant, but in Audition's Multitrack mode, options under "Default Stereo Input" include Mono > [01M] Line (AudioBox USB iTWo) 1 and [02M] Line (AudioBox USB iTWo) 2; but under Stereo >, it only offers [01S] Line (AudioBox USB iTWo) 1 as an option. And when I try to select Mono>[02M] Line (AudioBox USB iTWo), the feed it takes is the duplicated one from Microphone 1.

Couple of things: ASIO would be a better bet - all you need to do is sort out the output routing so you can hear it. But if this appears to have altered on its own, having worked fine before, it does sound rather as though Audition's preferences folder might have been corrupted; you really should be able to see L and R as separate inputs, and assign them independently. The only problem with resetting the Preferences folder is that you will lose anything you've set up specifically in Audition if you use the simple brute-force method - which is to restart Audition with the shift key held down. The alternative would be to navigate to the folder itself and delete the MachineSpecific Settings.xml file. This would automatically re-establish itself when you restart Audition. The path to the folder it's in is usually hidden, but it is 

 

C:\Users\[username]\AppData\Roaming\Adobe\Audition\13.0

 

It's hidden at the AppData point. Whatever else you try, it wouldn't hurt to re-establish that as a starting point, anyway.

Thanks, SteveG, for your advice. I'm sorry to say deleting the xml file didn't change anything; as you predicted, that file automatically re-established itself the next time I opened the program. But the mono (Channel 1) mapping to both L & R situation continued.

I'm curious to find out more about your suggestion, sorting out the output routing so as to hear playback in ASIO. Not sure what that might entail. Under "Device Class" ASIO I see options for 12 drivers, some of which sound like the same thing:"ASIO PreSonus FireStudio," "AudioBox ASIO Driver," "PreSonus DSP USB Series ASIO," etc....the device which worked so well, and which is no longer mapping, is PreSonus Audibox iTwo. Other options on that "Device" list sound like devices I used a long time ago (and for which I may have once loaded a driver).

In no case have I been able to get sound or playback out of Audition when I've chosen one of these ASIO devices.
