I had no trouble with call echo until the latest upgrade of call craph. I enabled your echo cancellation to no avail.

Please set the Audio I/O mode to Wave from the advanced panel of configuration and try again.

-I did this. It made a slight improvement in reducing the amount of echo.
I just downloaded v 1.2.0.0 and I still am getting an echo.

I have this problem too. I tried all the suggested solutions but nothing has changed. As soon as I turn off the Call Grapph the voice quality is perfect.All the problems happen by starting the Call Graph.
I would appreciate any comments.
April 13th, 2009 at 10:15 am
Are you using XP or Vista?
April 13th, 2009 at 10:45 am
Thank you for your response.
I am using Vista.
April 13th, 2009 at 11:10 am
Try enabling echo cancellation.
April 13th, 2009 at 11:55 am
I tried it. It did not help. I also tried both Audio I/O and Wave mode. These changes also did not help. I really need to find a solution for this problem.
Thanks
April 13th, 2009 at 12:13 pm
Can you please enable logging, run the interactive demo and send me the log file as well as the recorded file.
April 13th, 2009 at 12:23 pm
The point is that although the voice has echo, the recorded call is good. However it is really difficult to hear the voice of the other side during the call. I tried different headsets. I also tried it without headset but the problem still exist. And the strange point is that as soon as I start the Call Graph the voice turns to have echo and as soon as I stop recording the voice becomes clear.
April 13th, 2009 at 11:49 pm
are you getting the echo or your callers? which version of Skype are you using?
April 14th, 2009 at 8:29 pm
I am getting echo and I use the latest available version of Skype.
April 14th, 2009 at 8:46 pm
It is actually Skype 4.0
April 14th, 2009 at 11:53 pm
Try starting the recording before the Skype call. Also set the Audio I/O mode to wave from the advanced panel of configuration.
April 15th, 2009 at 8:40 am
I tried it. The call starts with echo and then when I stop recording the voice becomes clear.
Do you think it might be because of the version of Skype or Call Graph? I think this problem started when I did upgrade the Skype! Do you recommend using the older version of Skype?
April 15th, 2009 at 10:54 am
It has been tested with the latest version of Skype. The echo should go away if you switch to Wave I/O instead of DirectSound. Can you pls. enable logging and send me the log file once.
April 21st, 2009 at 12:55 am
I also get the bad echo with the latest version of Skype with both Wave I/O and DirectSound
April 21st, 2009 at 1:12 am
We’ll be coming out with a workaround for this in a day our two. Suggest you downgrade to Skype 3.8 in the meantime. Thanks for your patience.
April 21st, 2009 at 3:40 am
I’ll give it a try when you do, until it works I have simply stopped using callgraph
April 21st, 2009 at 6:11 am
I also get the bad echo with the latest version of Skype with both Wave I/O and DirectSound. I must use Skype v4 for certain features it has. I cannot downgrade to v3.8 at this time.
April 21st, 2009 at 6:58 am
We are working on fixing this issue. It will be out in a tomorrow or day after.
April 23rd, 2009 at 9:57 am
The workaround has been released. Please check the post for instructions.
April 24th, 2009 at 6:03 am
Hi there! Seems to be working fine when I call the “Echo / Sound Test Service”
By mistake I selected “Far End Echo” and the caller was almost inaudible on the recording. The correct setting for my problem is “Near End Echo”. Just mentioning it in case anyone does the same thing!
April 25th, 2009 at 6:26 am
Installed workaround and the nearside echo is gone
The only problem is it is no longer recording the far side voice
April 25th, 2009 at 7:21 am
have you authorized CG to connect to Skype after installing the fix?
April 25th, 2009 at 3:30 pm
I was experiencing the same symptoms even after installing the patch (CallGraphSetup_s4fix.exe). After installing the latest DirectX plugin (http://www.microsoft.com/downloads/MozillaValidation.aspx?familyid=2da43d38-db71-4c1b-bc6a-9b6652cd92a3&displaylang=en), then re-setting the Advanced configuration Audio I/O to Wave I/O, I no longer have near end echo. I do not have “Enable Echo Cancellation” checked.
April 25th, 2009 at 3:42 pm
We recommend that you have the Near End EC option checked if you’re using Skype 4. The API has changed. With this Near End EC enabled, there’s less work for Call Graph to do during the recording.
April 27th, 2009 at 11:25 pm
Rajiv,
Yes I had been prompted to allow the newer version access to skype and I had allowed it to connect
I tried it again after a reboot and it did appear to be recording voice and speaker but I could not hear anything
It wasn’t a good time to continue playing around with it so I have left it for now and am continuing to use advanced audio recorder as I happen to have that on this pc already
Presumably it was the near end echo setting that stopped me from hearing anything, but I haven’t had a chance to play with it yet
April 28th, 2009 at 1:31 am
What happens when you dont enable the Near End EC option?
May 5th, 2009 at 1:17 am
I had exactly the same problems and I solved them installing an older skype version (with 3.8.0.188 it works!!)
May 5th, 2009 at 2:17 am
Its a change in the Skype API which is causing this. The workaround fixes the issue.
May 5th, 2009 at 3:42 am
Rajiv,
When I didn’t enable it (at that time) I was getting echo… which is why I went and enabled it
The last time I recorded something it was picking up my end just fine and I can only faintly hear the “other” end
I went and got a new ucb headset a decent plantronics 625 usb model both to get better quality calls and reduce any bleed that I was getting from my older headsets
I am guessing that the very low volume far end recording that I am hearing now is probably as a result of bleed, that or the mic picking up what is coming from the headset speakers into the room
Is it possible (or could it be possible) to record the local and the remote to different channels if desired (or even to different mp3/wav files) ?
Some of the other recording programs allow this and it makes it easier to edit out unwanted local noise or unwanted remote noise after the fact by having each isolated to either the left or right channel
May 5th, 2009 at 4:16 am
If you record it in stereo mode the far end and near end are encoded in separate tracks. You can then post process each of the tracks individually using Audactity or other programs.
Note that if far end is not getting recorded, it is usually an issue with Call Graph’s connection with Skype. It takes around a minute or so after CG is started for the connection to be established. Once connected CG shows a notification saying that its ready to record. If you open the statistics window you’d be able to see the amount of data transferred between Skype and CG.
May 5th, 2009 at 9:00 am
Ok, I am giving it another try ; in my case callgraph had been running for a long time so it wasn’t just after CG had started
I opened the statistics window to see what I could see and callgraph ended up exiting with an error (after a non-answered call and I was pressing stop to stop the recording)
If you have registered with microsoft you can get the error report, if not it was :
Faulting application callgraph.exe, version 1.2.0.0, faulting module callgraph.exe, version 1.2.0.0, fault address 0x000181f0.
The MS exception report mentioned code 0xc0000005
May 5th, 2009 at 9:55 am
I tried several combinations but could not get the far side part of the recording to work
If you want to try further you could email me and we could try it interactively if you wish
May 19th, 2009 at 1:13 pm
I have an echo, but it is from CallGraph, it plays back the audio from the other person i am talking with, but no echo of my vioice, if i close call graph this problem doesnt happen. any idea on how to fix this? the echo doesnt show up in recordings, but is really distracting and makes it hard to understan my friends
May 19th, 2009 at 3:04 pm
That is the far end echo. Please follow the instructions above for removing far end echo.
May 19th, 2009 at 3:45 pm
Rajiv, I think maybe you understood me. It’s like skype is playing what the person I’m talking to is saying, but so is Call graph at a very slight (maybe 0.1 second) delay. i followed the steps above with no success. its not my mic cause the same thing happens if i have headphones plugged in.
May 19th, 2009 at 3:47 pm
Okay, weird issue on my end, not sure what’s wrong. When I do a test call, the first part and the part where I speak records correctly. However, when it replays what I say, and then when the woman starts talking again, I get the echo. This is only in the recorded version, I can’t hear it when Skype replays the call for me. I’ve tried changing it to wav, turning echos on and off, updated everything I could think of… any advice?
Thanks!
May 19th, 2009 at 4:16 pm
Kelly,
Can you pls. send me the recorded file along with the log file. To get the log file enable logging from the configuration -> general tab and record a test call.
Thanks!
May 27th, 2009 at 10:09 pm
I seem to be having a similar problem with echo but in the playback mode. There is no echo whilst recording but only when I play it back. On playback through my USB headphones I firstly hear the skype test recording with an echo in the right ear channel, then I hear my test recording very clearly in the left ear channel, then my message is immediately repeated in the right ear channel with echo followed by the closing recording by Skype in the right ear channel again and the echo is back! It looks like the echo is only happening in the right channel and not in the left! I have tried all different settings as described in the other posts to no avail. I have the latest Skype and the latest Callgraph on Vista 32bit. BTW, whenever I tried to reset the Advanced configuration Audio I/O to Wave I/O, I would lose the link with Skype. I think your program is awesome once I can fix this bug. Thanks!
May 27th, 2009 at 10:27 pm
Dora,
The echo you’re getting is the Far End Echo. It happens because of a feedback loop between your speakers and mic. Try the instructions mentioned for Far End Echo to see if it works for you.
June 12th, 2009 at 9:04 am
I have an echo from the person on the other end, who is using a headset.
It records that way too. It is most annoying for them and sounds awful.
I am using latest verison of Skype. I tried your fix for echo on other end but do NOT understand the following instruction
control panel and open your soundcards vendors setting (not the windows Audio) and check.
how do I open soundcards vendors? where is it?
June 12th, 2009 at 10:58 am
Karen,
Pls. try try enabling the Near End EC option from configuration -> advanced.
July 21st, 2009 at 9:17 pm
I’m using callgraph 1.2.1.1 with skype 4 and sometimes get an echo immediately and at other times it starts a few minutes into the call.
Trying to stop the recording – I get the last 5 seconds of voice repeating-repeating-repeating until I kill the program (just about freezes the PC).
I can’t change from direct i/o to wave – it just goes back to direct i/o and tells me to install the latest version of directx – (which is up to date).
Running on Xp-sp3.
Any ideas?
Thanks,
Rashid.
July 21st, 2009 at 10:14 pm
please try upgrading to the latest version of Skype. Also try reinstalling Call Graph.
October 6th, 2009 at 9:35 pm
the configuration will not update to ‘wave I/O’ i get a pop that says to update to the latest direct x. i have done that.
have checked both echo options
have updated to latest skype october 6th
using windows xpreinstalled call graph
October 6th, 2009 at 10:50 pm
Please try with the configuration dialog. Right click on the callgraph task bar icon and choose configuration from the menu.
October 6th, 2009 at 10:54 pm
thanks! i will try that.
also, what does speaker gain factor mean?
October 6th, 2009 at 11:36 pm
It automatically adds a gain (volume increase). Leave it a 1 if you’re not sure.
October 7th, 2009 at 1:19 am
Rajiv,
I still don’t understand why if there is ‘feedback’ between the headset and the mic that I do not hear it when I am using Skype and only hear it when callgraph is recording
It is also confusing that I need it enabled for a skype to skype call, and need to turn it off again to record a Skype-In call
Messing around with selecting or deselecting either type of echo correction from the options page is not as easy as it could be given that I need to change the option frequently
It might be useful to detect that either one side of the call (or the other) has not sound in the first part of the call and suggest a setting that might be needed (or suggest that you or the other person talk)
October 7th, 2009 at 1:30 am
We’re planning to address all the echo issues in the next release. If you’d like to try it out then let us know.
October 7th, 2009 at 7:32 am
still trying to eliminate echo
checked ‘wave I/O’ by right clicking task bar button(will not update by webpage)
have checked both echo options
have updated to latest skype october 6th
using windows xp reinstalled call graph
but
it locks up skype and the computer. i have to shut down by holding the power button
October 24th, 2009 at 4:14 am
Fix for the echo issue is now available. http://bit.ly/LukHi
