Chapter 5: Enhancing and
Restoring Audio
dobe Audition provides many tools you can use to repair audio and improve
sound quality. Powerful noise reduction features let you bring old recordings into
the digital age. And with a wide range of filter and amplification effects, you can
process audio to produce radio-ready sound or unique special effects.
About enhancing and restoring audio
If you need to add brilliance and impact to a new recording, or clean up the sound of an
old one, you can use several types of audio enhancement and restoration effects:
• Noise reduction effects that let you remove unwanted hiss, hum, clicks, or pops. (See
“Removing noise” on page 125.)
• Filter effects that let you change overall tonal balance, from rumbling bass tones to
sparkling highs. (See “Filtering audio” on page 129.)
• Amplitude effects that let you precisely control audio volume for increased radio
impact, detailed fade outs, and more. (See “Optimizing amplitude” on page 134.)
All of these effects are available in Edit View, but some don’t exist in Multitrack View.
Because the two views are linked, however, you can easily overcome this limitation. If a
multitrack clip requires noise reduction, for example, simply double-click the clip to
process it in Edit View.
About the mastering process
Mastering describes the complete process of restoring and enhancing audio files for a
particular medium, such as radio, video, CD, or the Web. In Adobe Audition, you can
master either individual audio files in Edit View or groups of files in a batch process.
(Batch processing is particularly useful if you plan to burn a group of files to CD. See
“About scripting and batch processing” on page 243.)
