More Help topics "Waveform measurements" on page 3 Reverse a waveform The Reverse effect reverses a waveform from right to left so it plays backwards. Reversing is useful for creating special effects. 1 If you want to reverse part of the waveform, select the desired range. Or, deselect all audio data to reverse the entire waveform. 2 Choose Effects > Reverse. Create silence Creating silence is useful for inserting pauses and removing nonessential noise from an audio file. Adobe Audition provides two ways to create silence: • To mute existing audio in the Waveform Editor, select the desired content, and choose Effects > Silence. Unlike deleting or cutting a selection, which splices the surrounding material together, muting leaves the duration of the selection intact. • To add silence in the Waveform or Multitrack Editor, either position the current-time indicator or select existing audio. Then choose Edit > Insert >Silence, and enter the number of seconds. Any audio to the right is pushed out in time, lengthening duration. Multitrack clips are split if necessary. More Help topics "Delete Silence and Mark Audio options" on page 80 Analyzing phase, frequency, and amplitude Adobe Audition provides several ways to analyze audio. To compare phase relationships between any two channels, use the Phase Meter panel. To analyze tonal and dynamic range, use the Frequency Analysis and Amplitude Statistics panels. The Waveform Editor also provides Spectral Frequency Display, which you can use together with the analysis methods above. (See "Displaying audio in the Waveform Editor" on page 35.) Analyze phase The Phase Meter panel reveals out-of-phase channels for stereo and surround waveforms, which you can address with the Effects > Invert command. (See "Invert a waveform" on page 48.) This panel also helps you identify highly in-phase channels that will sound similar if summed to mono. (See "Convert a waveform between surround, stereo, and mono" on page 53.) To understand audio phase, see "How sound waves interact" on page 4. 1 Choose Window > Phase Meter. Last updated 2/16/2012

Reverse a waveform
The Reverse effect reverses a waveform from right to left so it plays backwards. Reversing is useful for creating special
effects.

If you want to reverse part of the waveform, select the desired range. Or, deselect all audio data to reverse the entire
waveform.

Create silence
Creating silence is useful for inserting pauses and removing nonessential noise from an audio file. Adobe Audition
provides two ways to create silence:
To mute existing audio in the Waveform Editor, select the desired content, and choose Effects
> Silence. Unlike
deleting or cutting a selection, which splices the surrounding material together, muting leaves the duration of the
selection intact.
To add silence in the Waveform or Multitrack Editor, either position the current-time indicator
or select
existing audio. Then choose Edit
> Insert
>Silence, and enter the number of seconds. Any audio to the right is
pushed out in time, lengthening duration. Multitrack clips are split if necessary.

Analyzing phase, frequency, and amplitude
Adobe Audition provides several ways to analyze audio. To compare phase relationships between any two channels,
use the Phase Meter panel. To analyze tonal and dynamic range, use the Frequency Analysis and Amplitude Statistics
panels.
The Waveform Editor also provides Spectral Frequency Display, which you can use together with the analysis methods
above. (See “
Displaying audio in the Waveform Editor
” on page
35.)
Analyze phase
The Phase Meter panel reveals out-of-phase channels for stereo and surround waveforms, which you can address with
the Effects > Invert command. (See “
Invert a waveform
” on page
48.) This panel also helps you identify highly in-phase
channels that will sound similar if summed to mono. (See “
Convert a waveform between surround, stereo, and mono
on page
53.)
To understand audio phase, see “
How sound waves interact
” on page
