Adobe Audition: Apply Dynamics Compressor to balance audio

Demo summary

The user demonstrates applying a compressor via the Dynamics effect, selecting a 'soft compression' preset and manually adjusting the threshold to -15.4 dB and the ratio.

Step-by-step

  1. Open the Dynamics effect panel
  2. Select the 'Soft compression' preset as a starting point
  3. Ensure only the Compressor checkbox is selected (uncheck Autogate and Expander)
  4. Adjust the Threshold slider to approximately -15.4 dB
  5. Set the Ratio slider to a value between 2 and 4
  6. Apply the effect to the audio

Options

  • Use Autogate or Expander within the Dynamics panel
  • Use the 'Soft compression' preset without manual modifications

Watch out for

  • The compressor and EQ are complex concepts that require effort to learn
  • Too much compression will make the audio sound unnatural
  • The suggested threshold settings (-15 to -18) depend on having normalized the audio to -3dB first

Tips

  • Use a threshold between -15 and -18 for typical recordings
  • Set a ratio between 2 and 4 for standard voice recordings
  • Experiment with the ratio and threshold to find the best balance for your specific recording
  • Use Dynamics because it is simpler to configure than standalone compression tools

Highlights

the compressor and EQ are a bit complex concepts and you will have to put some effort into learning them
