Thread: Phone echo

Echo is a known issue on all the BT solutions coming out. The only two solutions I am aware of are a software Half Duplex mode, where the mic automatically mutes when the person on the other end of the call is talking (this is how most OEM car kits work) or a PCI card like the Phoenix SOHO which cancels echo in Full Duplex mode.

Is there a way in CF or windows to do this.

I can't use PCI cards I use the Turtle Beach USB card.

Is the Full Duplex on the mic itself

you can use a hardware echo cancelling microphone, this can solve the issue...

We are also looking into software echo cancellation integrated into Centrafuse directly...

Would the Andrea mic work in this case?

Do you have any examples of such mics? This is the reason why i have never been able to use cf phone feature. There must be a way to do it from the software side as messenger and skype dont have this problem.

Any echo-canceling microphones I've seen are north of $300. Don't think that's a valid option.

I get a pretty bad echo on my setup. I have a logitech USB noise cancelling mic installed at the top end of my driver's side A-Pillar. It sound great, even with the window open, but the echo on the other end of the convo is horrible. I can't really turn the speakers down because I would not be able to hear the convo. Can we incorporate a software cancelation in the Centrafuse 2.0 phone software? I know its new and has bugs so I am not complaining. Can this be done effectively though? (not too much cpu stress)

Currently I cannot use the phone software as the pc lags and/or freezes after some use.

What are the most common ways of echo cancelation?

Remember that echo-canceling and noise-canceling are two completely different and independent technologies. Noise-canceling is much easier (and cheaper) to achieve. In fact, most so-called "echo canceling" mics are very expensive and geared toward businesses who use conference calling. Even if the money were spent on one of these mics, I'm not sure it would operate as desired in a car pc environment.

As far as I've seen, the only two solutions available are a half-duplex mode built into the phone solution (software solution) or an additional card like the Phoenix SOHO card (hardware solution), which requires that you have an available PCI slot.

Let's hope the CF team can get a half-duplex mode built-in to the module.
