Audio is blank
Blank audio is usually caused by capturing the wrong audio channel. To set the correct channel:
1 In the taskbar notification area, right-click the speaker icon.
2 On the context menu, click Recording Devices.
3 In the Sound applet, left-click the channel to record, such as Stereo Mix or What-U-Hear.
4 Click the Set Default button.
If needed, adjust the channel's volume.
5 Click Properties.
6 Click the Levels tab.
7 Adjust the Volume and Boost (if available).
Sometimes a +30 dB boost is needed for microphones.
Sometimes we've had to close applications and repeat the above procedure several times before it would work.

Maximizing sound quality
For maximum sound quality, set recording volume to about 5 on a scale of 6, sample rate to 44KHz and sample size to 16 bit. To access these settings, click Settings / Options on the capture bar, then click the Audio tab. Note that captured audio can never exactly match original files because it’s sampled asynchronously.
