Monitoring audio levels
While you're recording, a responsive meter is displayed  in the track header to monitor the incoming signal 
level of the selected  recording device. It is important that you record with the highest signal  possible 
without clipping. 
When a track is armed, the track meter displays the track's  input level. If input monitoring is not on, the 
meter displays the level  of your input source. If input monitoring is turned on, the meter shows  the level of 
the input source plus the track effects chain.
A reading of 0 dB is the maximum for a digital signal. Clipping  occurs when the incoming signal is too high 
to be represented as a digital  value. The result is distortion in the recording. A clipped signal will  be 
indicated by a red Clip  warning at the top of the meters.
Right-click the meters and choose a command from the shortcut menu to adjust the display of the meters.
Toggling record input monitoring
If you're using a low-latency audio  device, Vegas Pro can perform  record input monitoring so you can hear 
your recording signal with real-time  track effects.
To turn on input monitoring, click the Record  Input button    and choose Input  Monitoring On or Input  
Monitoring Auto from the submenu. During recording, your signal  will be played back with the current 
track effects chain, but a dry (unprocessed)  signal is recorded.
