# Audio Tips

Camtasia Relay records audio from one audio input source. This includes built-in microphones common on many laptops.

You cannot change the audio input selection once you start recording.

Audio Tips

Verify you are recording the correct audio input.

Make a test recording. If you are using an external microphone, move away from the computer and speak to ensure you record the external microphone and not a possible built-in microphone on the computer. Verify desired audio input devices are enabled.

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. Macintosh laptop computers line-in ports are not powered. This means you must rely on the internal microphone or purchase an external (powered) microphone.

Adjust the input level.
Speak in your presentation voice and adjust the audio input slider so the volume indicator peaks near the end of the bar. You can adjust the audio input level before and after you start recording.
