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 presen-
tations.
In the Editor panel, select the audio you want to adjust. (To select an entire file, triple-click.)

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

video.
Do either of the following:

• To add a specific duration of silence, position the current-time indicator where you want silence to begin.
Choose Edit > Insert Silence. If you're adding silence, specify a duration in seconds, and click OK.

Visually identifying noise
In the spectral display, you can quickly identify and select different types of noise. Clicks and crackle, for example,
usually appear as bright vertical bars that extend from top to bottom. Hiss, meanwhile, appears as a light-red cloud
that extends across the top.
