VOIP echo problemo

Hi all,

I did some research on the problem of getting echo when using Skype to Skype
contact with a friend. Trying to cut through all the jargon on the VOIP
forums, I figured out that echo generally occurs if the other guy has a slow
connection and my voice signal is delayed at the other end so my voice comes
back at me. Is that right?

I would really appreciate some plain English advice on this, before I spend
moey on stuff I don't need, like noise cancelling mikes. BTW, there is no
echo when I use my Skype account to ring my friend's landline phone.

Paul

What's happening is that the sound of your voice is being produced by
the remote speakers and picked up by the remote microphone, which
transmits it right back to you. It's not necessarily a result of a
slow connection, since Skype adjusts for that by altering its
bitrates; it's that it takes some amount of encoding time to
translate audio to digital on the local end and digital to audio on
the other end. The reason there's no echo on the landline is that
the speaker and the microphone are separated -- it's not that the lag
isn't there, but you aren't aware of it because you aren't hearing
the echo.

The simplest solution is for your interlocutor to use headphones --
that way, the sound won't make it back to the microphone on his or
her end.

I have found that the normal cause of echo is feedback caused by the
person you are talking to listening through speakers. Your voice is
coming our his/her speakers an entering their microphone. The cure is
use a headphone. at both ends.

Re: VOIP echo problemo

I have the same problem. Me on Mac and other on Windows machines get a terrible echo as my Powerbook mic feedback from the speakers. It's funny this should happen with skype. I used to use iVisit which had a squelch slider which did a pretty good job of cancelling out the echo.

The problem is if you have headphones, only you can hear the conversation - no fun when the kids want to have a "group" chat to uncle in another city. What do you do? Damian

Would the problem of echo on Mac laptops be solved if external speakers were
plugged in and positioned strategically away from the inbuilt Mike? I have a
G5 Mac and a Dell PC. I use the PC for Skype because it is easier to get
mikes for PCs. Macs require wierd types of mikes! LOL.

I speak into a mike and listen on my two speakers connected to the PC. No
problemo! Is this a generic laptop problem, or is it specifically a Mac
lapto problem?

Re: VOIP echo problemo

The problem I have, unlike one of the contributors above, is that Mac to landline is usually so poor that it's not worth continuing (the other party is usually a long way away, thanks to me living in Sydney), while even over a lesser distance it's never as good as Mac to Mac. (Headphones are worn by the Mac party at all times!) I'm curious as to the reasons for this, but would really love tips on how to overcome the problem.

Re: VOIP echo problemo

I've now plugged in external speakers and pointed well away from my laptop. No sound coming out of the powerbook's speakers. The pc on the other end can still hear a slight echo. Damian

Are you talking with someone on another computer or to a telephone?

Re: VOIP echo problemo

I am using a Yealink USB Cordless phone and Skypeout. The person I call on their landline hears a terrible echo. I do not hear it. When I use a USB Headset there does not seem to be the same problem with echo. I am using a PowerBook Titanium with OS X 10.4.9.

Any ideas?

1)  Keep using the USB headset till the problem is solved.  8-)

2)  Do all calls to landline phones give the same result ?

3)  When your Yealink cordless phone is in use are your loudspeaker on or off ?

4)  When your Headset is in use are the same loudspeakers on or off ?

5)  What kind of system does the person you call have ?  Cordless phones that can be placed in their cradles and talked to while walking around...  etc ?  Or old style phones that are held to the ear.

I hope that you get some useful answers,
