How to capture Windows Vista audio
You can capture any sound on your computer, including streaming audio, DVDs or a microphone. To give you an idea of what's possible, at the right is an actual example of streaming audio captured from the net.

The trick is setting which channel to record. It's not obvious, but these instructions will show you how. Please print the instructions to make them easier to follow.

Instructions for pre-Vista operating systems.

Note, audio capture is not available under Windows Remote Desktop. Instead, install CaptureWizPro on the local machine.

If you're recording audio and video, be sure Include audio is checkmarked in the CaptureWiz Options dialog.
Open the Windows Sound applet, using this CaptureWiz shortcut.

1 On the capture bar, click Capture / Options.

2 In the Options dialog, click the Video tab, then the Settings button.

Tip, you can also access the Sound applet from the Windows Control Panel by clicking Hardware and Sound, then Manage audio devices, then the Recording tab.

Here's the window for selecting which channel to record.

3 In the applet, left-click, then right-click, the device to record.

4 In the context menu, checkmark Set-as-Default.

Unfortunately, each audio card uses different channel names.
Look for a channel named something like this:

Stereo Mix
Sum Balance
Wave Out Mix
Record Master
Stereo Mixer
Wave/MIDI/CC
What U Hear
Mixed Output

To record your voice, use the Microphone channel.

Sometimes we've had to close application and repeat this several times before it would work. If we'd writen this part of Windows we would have made it easier!
If needed, adjust the devices's volume.

5 Click Properties.

6 Click the Levels tab.

7 Adjust the Volume and Boost (if available).

Sometimes a +30.0 dB boost is needed for microphones.

The moving green bars indicates live sound.

Tip: If your audio card doesn't provide a channel for recording the sound going to the speakers, you can use a Y connector to connect the computer's speaker jack to it's microphone jack. For details click here.

Alternatively, install a standard audio card.
