Configure Audio Devices

 

Before you start a recording, you should make sure that your audio devices are set up properly. Click "Audio Devices" under the "Tools" menu to configure your audio devices. Note that only the meet host can record a meeting.

You can choose to have

  1. No audio
  2. Single input: to record audio from one input source, such as a microphone.
  3. Dual input: to record audio from two input sources. Dual input is only enabled if you have more than one audio device (sound card) in your computer and you are running Windows XP.

You need to choose an audio device for each input if you have more than one audio devices in your computer.

You can check the recording level for each input by watching the volume gauge.

Recording from Microphone

If you are the only speaker in a meeting or you are creating a recording for playback, you can simply connect a microphone to your computer and record from it. In VShow, select Tools/Audio Devices and check "Single input".

Recording from Telephone

If you want to record a telephone call with your meeting, you need to use a telephone recording adapter to connect your telephone to your computer's microphone input. You can purchase a phone recording adapter from DynaMetric  (http://www.dynametric.com)

Some telephone recording adapters (DynaMetric TMP-636S) have bi-directional connection and let you record both your telephone call and computer audio. You need to connect your computer audio output to the adapter. Anyone on the phone call will hear the audio played from your computer too.

You should select "Single input" in "Audio Devices" if you are recording from a telephone.

Recording Computer Playback Sound

If your sound devices support sound mixing, you can set VShow to record sounds playing from your computer speakers. This is useful if you wan to record sounds from an audio clip playing on your computer. You can also use it to record two-way conversations from an Internet phone, such as Skype. See Recording Skype for details.

To set up VShow for recording sounds from the computer, select Tools/Audio Devices and check "Single input". In Audio input 1, select "Default device". You need to set up your Windows sound device settings to record from "Wave Out Mix". Click here to see how to set up your Windows Sounds and Audio Devices Properties. Check the selected boxes shown in the picture based on your needs:

  • Recording from microphone only: Check Box 1 and 2 (standard settings)
  • Recording computer sounds only: Check Box 1 and 3
  • Recording both microphone and computer sounds: Uncheck Box 1, Check Box 3

If your sound device does not support sound mixing, you can simply use an audio cable to loop the audio output back to the microphone input of your sound device. You can set up VShow to record from the microphone input.

If you are running Windows XP, you can also set VShow to record from two audio input sources using the method described below.

Recording from Two Audio Sources

Windows XP only

Recording from two audio sources allow you to record from a microphone and a second audio input, which can be a second microphone or a line-input from an audio player. You will need to have two sound devices on your PC and the PC needs to be running Windows XP.

Set "Audio Devices" in VShow to "Dual input":

In this setup, your voice is recorded from a USB headset. The second audio input is coming from another sound device's input. The sound from the second input is echoed in the first audio input so you can hear it in your headset.

Audio Webcast

Audio webcast allows you to broadcast your voice to all meeting attendees who join the meeting with a Web browser (See "Attending Meeting"). Attendees will hear the audio via their computer speakers. 

To enable audio webcast for a meeting, follow the description in "Edit Meeting".

As with audio recording, only the meeting host can perform audio webcast. If you have multiple speakers in a meeting, you should set up a teleconference for all the speakers to call in. Follow the description in "Recording from Telephone" to webcast the teleconference to all attendees.

The following diagram shows you how to set up a meeting with audio webcast.

You can also webcast your Internet phone conversations to all attendees. The step up is the same as "Recording from Two Audio Sources".

Notes:

  1. The audio webcast usually has a 5-second delay (the delay varies depending on your Web site traffic and connection speed). The audio may not be in sync with your meeting events, such as shared presentations or desktops, which have a shorter delay.
