Techniques for restoring audio
You can fix a wide array of audio problems by combining two powerful features. First, use Spectral Frequency
Display to visually identify and select ranges of noise or individual artifacts. (See “Select spectral ranges” on page 73
and “Select artifacts and repair them automatically” on page 74.) Then, use restoration effects to fix problems like
the following:
• Crackle from wireless microphones or old vinyl records. (See “Automatic Click Remover effect” on page 142.)
• Background noise like wind rumble, tape hiss, or 60-cycle hum. (See “Adaptive Noise Reduction effect” on
page 141.)
• Phase misalignment from poorly placed stereo microphones or aging analog tapes. (See “Automatic Phase
Correction effect” on page 142.)
The VST-based restoration effects above, which are available in both Edit View and Multitrack View, quickly address
common audio problems. For unusually noisy audio, however, consider using offline effects unique to Edit View, such
as Click/Pop Eliminator, Hiss Reduction, and Noise Reduction.

Adaptive Noise Reduction effect
The Restoration > Adaptive Noise Reduction effect quickly removes variable broadband noise such as background
sounds, rumble, and wind. Because this effect is VST-based, you can combine it with other effects in the Mastering
Rack and Effects Rack and apply it to tracks in Multitrack View. By contrast, the standard Noise Reduction effect is
available only as an offline process in Edit View. That effect, however, is sometimes more effective at removing
constant noise, such as hiss or hum.
