I recently bought a  Logitech C920 that came with software that lets you record audio and video, yet it comes up very short on audio quality.
 
The webcam has a built in microphone but also lets you use another audio source. The software allowed me to select the first recording channel on my audio interface. My recording from that channel had a lot of noise like high static. I falsely assumed it was my recording chain and tore half my studio apart to re route cables and eliminate sources of potential noise. I later discovered that using the same recording chain in Sonar had no noise. This points to a bad software/driver design in the webcam software. 
 
I'm looking for an alternative solution. Maybe a program that records  audio and my webcam stream but has better audio capability.
I wish Sonar could see and record a webcam. 
 
The long way around is to use Sonar to record audio while simultaneously recording video to the Logitech software. I have done this. It's a lot more work since you have to import the video into Sonar and align the recorded track to the video and delete any video the cam might have recorded.
 
Any ideas?

The high static is probably caused by digital drop-outs (buffer overflow). The first thing to try would be to increase your audio buffer size.
 
When you set the Logitech to channel one of your audio interface, the Logitech software is most likely using the WDM driver for your (Presonus) audio interface.
 
You need to find the option (if it exists) to increase the WDM audio buffer size. Look in the Logitech software for a way to increase the audio buffer size,  and also look in the Presonus software for a way to increase the WDM buffer size.
 
 

I record the webcam audio/monitor audio as well as audio through my RME. Then I import all into sonar and bump the tracks into alignment. It is pretty easy.

I am using Sony’s Movie Studio Platinum 12.0 (MSP) and do kind-off the opposite in that I import the video and its corresponding audio into MSP from an iPhone or my video camera and then separately manipulate the audio in Sonar (ultimately bringing it back into MSP) … no webcam though.
 

Just out of curiosity ... are you able to copy the audio track that you recorded with the noise on it and evaluate it separately in Sonar?
 
I am wondering if the noise wasn't recorded but just occurs on playback through the webcam software.
 
When I import audio/video into Movie Studio either from a phone or my "old" video camera, all I have to do is ungroup the audio and video and then save a copy of the wave file.  At that point I just manipulate the audio file in Sonar.

Hmmm, I hadn't thought about my buffers. FWIW my Presonus interface is not using WDM drivers in Sonar, but maybe it's switching to WDM when using the camera?
 
The Logitech 920 has some kind of gate or  squelch built into it. I had suspected that maybe this was a part of the problem.
 
Dave I can record the track fine, it just has the noise in it. The funny thing is I don't hear the noise when recording, only after.
 
I recorded an acoustic guitar track the other day and ran both the Logitech recording program for the camera and Sonar for the audio at the same time. The whole process feels a bit clunky to me. It didn't strain my computer and the end result after a little work was nice. Just seems to be more than necessary, but this might be the best I can do.
 
Imagine sitting there with a guitar, starting the video recording and then starting Sonar. I mess up and need to retake a half dozen times doing that. Then afterwards importing the video, lining up the tracks. I get carried away on the mix so I spend an hour playing with reverbs, compressors and EQ. All said and done the production took way longer than the actual playing. Would be nice if one program could take both sources...but then, I suppose a lot of things would be nice :)

That particular camera has drivers geared toward its proprietary Logitech software, so is hard to find generic solutions. But you can easily record another mic and use a clapper board to align the audio/video to all tracks prior to any editing. With ripple delete, this will keep all tracks in sync throughout, but only video editors come to mind for doing this. I would not attempt this in SONAR.

Thank you.   I might need a video solution with great audio capabilities. I have the camera plugged into a usb hub. I wonder if I moved it to a direct usb connection if this would make any difference?

I have a Logitech C920 too.  I just tried recording a video using my Focusrite 6i6 as the audio source and the audio was fine - none of the static you describe.  Maybe it's some incompatibility between the Presonus driver and the Logitech software.  Do you have any other audio interface you can try?

Hmmm. No I don't have another interface.  Maybe I have a dud.
