2 Right-click the music track that you want to “duck” and choose
Audio Ducking.
3 In the Audio Ducking dialog box, adjust the following sliders:
• Ducking Level — determines the volume decrease. Higher
numbers indicate lower volume.
• Sensitivity — determines the volume threshold (read from the
track above the selected track) required for ducking to occur.
You will likely need to readjust the
Sensitivity slider to achieve
the results you want.
• Attack — determines the time it takes to lower the volume to
the
Ducking Level setting after the Sensitivity threshold is met.
• Decay — determines the time it takes to return to the regular
clip volume from the
Ducking Level
