Managing vChat Audio Quality
Managing vChat Audio Quality in JellVideo
If you are using JellVideo in a “Hands-Free” mode then the last thing you want in your video meeting is acoustic echo or a poor audio connection. But what can you do? First you have to determine who in the meeting is CAUSING the echo. If the echo you hear is yourself, then you are not the problem. The person on the vChat who asks “What echo?” is the source.
Note: JellVideo is set at the server to use enough bandwidth to ensure outstanding audio and video quality. If you continue to have issues, open a support ticket at http://www.jellnet.com/JellTicket. A customer service representative will then set-up a vChat with you to diagnose the issue. Before you contact support we would appreciate you reviewing these instruction, as the rep will go over them with you.
Here are ten possible ways to eliminate echo and improve audio quality on your next JellVideo vChat:
1) Reboot– If you are having issues, a good start is to reboot your PC with any external devices (Camera, microphone, speakers) attached. Right click on the speaker icon and make sure Windows default setting is using the correct mic and speakers. Then immediately enter a JellVideo meeting without detaching and reattaching the external device you are using.
2) Windows Setting Changes- If you make any changes to your windows settings exit your browser and then re-open your browser and enter the vChat.
3) JellVideo Device Settings– When you enter a JellVideo meeting, make sure the default audio and camera devices shown on the meeting entry screen are set to the devices you wish to use for the meeting.
4) Acoustic Echo Cancellation (AEC) Software – The Windows operating system has echo cancellation technology built in and most video calling software either uses what Windows provides or builds on it. Our experience is that Windows 7 and Vista do a better job that XP, so if you are relying on the Operating System to do your AEC, you’ll have better luck with the newer platforms. If you are still having issues consider testing an audio device driver from Solicall. SoliCall Pro can significantly improve audio quality.
However, AEC only has a chance to work when the mic input and speaker output go through the same central point. If your mic input is a USB webcam, and your speaker output comes from the integrated sound card, it is virtually impossible for AEC software to tell what is echo and what is “good” input. Also, some rooms just have too many inputs, outputs and bouncing sound waves for the software to “read” and adjust properly, so you need another solution.
5) Use an external Echo Cancelling Microphone and Speaker Device (ECM) — An ECM is actually a microphone and speaker built into one unit. JellVideo recommends the Logitech BCC950 which is a USB device that contains the camera, mic and speakers all in one unit. It also includes a nifty remote control. Other hands free devices work well too from manufactures such as Polycom or Clearline.
6) Use Headset / Ear Buds – Using a headset takes your speaker output and feeds it directly to…your ears. No sound coming out of the speakers, means no feedback into microphone and no echo on your call.
7) Adjust input/output levels or location — I was on a call with an associate who was generating echo. We reduced his mic sensitivity and the echo went away. Similarly taking the speaker volume down can mean the speakers aren’t loud enough to feed back into the mic and thus no echo. Another strategy, is to move the mic relative to where the speakers are. Moving the mic away from the speakers can help eliminate an echo.
8) Adjust Flash AEC- While in a vChat if you right click, a Flash menu will appear. Make sure the AEC option is set to On.
9) Windows Listen Option– Under the microphone properties in Windows 7 on the Listen tab there is an option “Listen to this device”. Try turning that off and the echo might go away.
10)Bandwidth – If you are experiencing issues such as delayed video images or delayed speech, then your router may be having an issue. An associate who works out of his home with a Comcast internet connection occasionally needs to reboot his router to restore optimum speed.
