Audacity: Monitor and adjust input levels

Demo summary

The demonstration shows how to enable 'Silent Monitoring' on the recording meter to check for clipping and adjust the gain slider to stay below -6 dB.

Step-by-step

  1. Click the small microphone icon on the recording meter.
  2. Select 'Enable Silent Monitoring' to see input levels before recording.
  3. Talk into the microphone as you would during the actual recording.
  4. Observe the meter to ensure levels do not enter the Red Zone (above -3 dB).
  5. Adjust the gain slider within the meter or on your hardware to keep levels below -6 dB.
  6. Click 'Disable Silent Monitoring' once levels are set.

Options

  • Drag the meters to resize or reposition them for better visibility
  • Double-click the slider icon to open a popup with a larger gain slider
  • Adjust gain via the Audacity slider, an audio interface, or a microphone gain knob

Watch out for

  • Recording in the Red Zone (above -3 dB) causes clipping or distortion that cannot be fixed in post-processing.
  • Avoid recording levels that are too low, such as audio that never crosses -24 dB.

Tips

  • Aim to stay below -6 dB during recording as a general guideline.
  • Keep the Audacity gain slider at 100% and adjust levels via your audio interface hardware if possible.
  • Prioritize talking from a proper distance to the microphone to ensure the best recording quality.
  • Use a larger meter size to make reading levels easier.

Highlights

if you can make sure the levels are okay there will be less headache after processing
