Re: [AG-TECH] Tabletop-Room mic with integrated echo canceling


That's very interesting. I've found the AccuMic's to be almost TOO sensitive and have the gain way down else I've seen we distort or even that the echo-cancelling gets overloaded. The version I have tested most with is an older AccuMicVC, with RCA-jack adaptors that is in use on the AG node here. The machine running the audio and the video capture is a Linux machine with an Intel ICH5 chipset (OSS sound).

Fred,

We ran into this same when we first started using the ClearOne AccumicPC with a Dell XPS at UCSF. We noticed that the sound level according to RAT was very low. There is an advanced sound setting where there is a check box for a "20dB boost" for the mic input (I don't remember the exact number for the boost as it's from memory). Clicking on this check box increased the sensitivity of the ClearOne tremendously, and now they would great for us.

This discussion of the ClearOne AccumicPC is really interesting to me,
because I've been very unhappy with the performance I've gotten from them so
far. We have a couple attached to a fairly new Dell and they don't pick up
well at all. You pretty much need to have the saucer right down in front of
you and speak loud toward it in order for other sites to understand you.
Since quite a few of you like the AccumicPC and I've not really had a chance
to test these on another PC or Mac, I suspect that my Dell's Sigmatel HD Audio
interface could very well be the problem (and there's other problems associated
with HD and rat)... not the Clearones.

Hi Michael
We use Clearone Accumic in one of our nodes. It works well and plugs
straight into a 3.5mm PC-audio-in.

Hello everyone!

I am a bit in trouble as I need to order a tabletop mic with integrated
echo cancelation quite fast, however don't have experience with them.
So I would like to rely on your experiences.
So can anyone recommend one or two of such mics, which work fine and
produce good results, for direct connection into a 3.5mm PC-Audio-in?
I have just had a look at the follwoing Clearone Mic (
http://www.clearone.com/products/product.php?cat=4&prod=17 ),
which seems to be able to work on PCs directly. Does anyone of you
already have experience with this one?


Thanks in advance
Michael
