There are a couple of possibilities for this problem, which you could check:
- Can you see any colour bars appearing on the Level meter at the right of the screen? If not it means that sound is not getting into the Sing & See software. The simplest thing to check is whether the microphone is actually plugged into the right place, and of course whether it is switched on (an easy mistake – I have done it myself!)
- Do you have more than one audio input device on your PC? For example a webcam could have its own audio input. Sing & See simply selects the “default” Windows audio input device, so you need to make sure that you have selected the appropriate device in the Windows “Sound” control panel. You can access this from Sing & See by clicking on the “Options” menu then “Audio Properties”. Click on the “Recording” tab and select the appropriate microphone input device.
If you have a “Professional” audio input device you may need to check that it supports “WDM” channels – see this page here for more details.
