JSI Tip 5816. Why must we take turns speaking during a NetMeeting conference?

If both parties cannot speak simultaneously, you may have half-duplex audio instead of full-duplex audio.

Full-duplex audio works like a telephone conversation and half-duplex audio is like a two-way radio, where you must press the send button to speak and release it to listen.

Full-duplex requires:

- A full-duplex sound card.
- A full-duplex sound card driver.
- Having full-duplex audio enabled in NetMeeting.
- Other conference participants must also have full-duplex audio capability.
- Speakers or headphones, and a microphone.

To determine if your sound card and driver are capable of full-duplex audio:

1. Start / Programs / Accessories / Multimedia or Entertainment / Sound Recorder.

2. Start a second occurrence of Sound Recorder by repeating step 1.

3. Play a long wav file in the first session.

4. While the the wav file is playing in the first session, record a .wav file in the second session. If you can record while the other session plays, you have full-duplex audio.

To verify your NetMeeting settings:

1. Open NetMeeting and press Options on the Tools menu.

2. Select the Audio tab.

3. Make sure that the Enable Full Duplex Audio box is checked.

NOTE: To adjust your sound to the current (ambient) environment, press Audio Tuning Wizard on the NetMeeting Tools menu.

NOTE: If you can only use half-duplex, try saying Over when you finish speaking.
