CrazyTalk doesn't have options to adjust the audio levels on input, instead it just uses the default system settings for your microphone.
If the volume level of your microphone is too low you should be able to adjust it in Windows.
Open up Control Panel and go to Hardware & Sound > Manager Audio Devices > Recording tab. Now select your microphone and click Properties where you can test and set the input level of your microphone.
