Audio Tips

Use the following tips to help you get the best audio in your presentation.

Verify you are recording the correct audio input.

Make sure you click the Audio Device button and then view all available devices while speaking into your microphone. Click to choose the device based on the input levels. The names of devices can be deceiving and viewing the levels of all the connected devices helps you choose the correct device.

Make a test recording. Speak in your presentation voice and volume.

If you are using an external microphone, move away from the computer and speak to ensure you record the external microphone and not a potential built-in microphone on the computer.

Use the Windows Control Panel to verify desired audio input devices are enabled and working properly. 

Use auto adjust or manually adjust the input level.

If the audio levels are too high and “clip” when recording, the quality of your processed presentation will be poor. Presentations recorded with poor audio also have a low level of accuracy in captions and full audio search (when transcription is provided by the profile).

If you are not using the option to automatically adjust the audio input levels, make sure to adjust the audio level appropriately. Speak in your presentation voice and adjust the audio input slider so the indicator peaks near the end of the green bars and is not consistently showing red bars. You can adjust the audio input level before and after you start recording.

Manually adjust the audio level.

When the audio meter reaches red levels, your audio level is too high. Enable the auto adjust option or move the audio slider to the left to decrease the input level. 

Audio level is too high. 

Obtain a good external microphone.

Some computers have decent built-in microphones. Some do not. It might be worth investing in a USB or line-in microphone.

Verify audio inputs are enabled.

Click Start > Control Panel > Sound (Sound and Audio Devices on Windows XP). Verify that audio inputs are enabled.

If necessary, use a powered audio input.

Some laptops do not have powered audio input ports. This means you need to use a powered microphone or a USB microphone.
