Maximize volume

After you edit audio and apply effects, maximize volume as a finishing touch. Soundbooth offers two techniques that raise volume to 0.3 dBFS, just below the digital maximum, ensuring optimal volume while avoiding clipping. Normalizing retains dynamic range by amplifying an entire file equally. Hard limiting reduces dynamic range by amplifying quieter sounds more than loud ones.

Apply hard limiting to increased perceived volume and make your audio stand out in web, video, or radio presentations.


  1. In the Editor panel, select the audio you want to adjust. (To select an entire file, triple-click.)
  2. At the bottom of the panel, click the Louder button  once to normalize audio, or multiple times to apply hard limiting.

    With each successive click of the button, Soundbooth increases overall volume by 3 dB. Hard limiting prevents clipping.

    To separately apply Normalize and Hard Limiting commands, use the Processes menu.
