USING ADOBE AUDITION
Importing, recording, and playing audio
Last updated 2/16/2012
If amplitude is too low, sound quality is reduced; if amplitude is too high, clipping occurs and produces distortion. The
red clip-indicator to the right of the meters lights up when levels exceed the maximum of 0 dB.
To clear clip indicators, either click them individually, or right-click the meters and choose Reset Indicators.
Customize level meters
Right-click the meters and select any of the following options:
Meter Input Signal
In the Waveform Editor, displays the level of the default hardware input. (See “
Configure audio
inputs and outputs
” on page 18.) To quickly enable or disable this option, double-click the meters.
Range options
Change the displayed decibel range.
Show Valleys
Shows valley indicators at low-amplitude points.
If valley indicators are close to peak indicators, dynamic range (the difference between the quietest and loudest
sounds) is low. If the indicators are spread far apart, dynamic range is high.
Show Color Gradient
Gradually transitions the meters from green, to yellow, to red. Deselect this option to display
abrupt color shifts to yellow at -18 dBFS, and red at -6.
Show LED Meters
Displays a separate bar for each whole decibel level.
Dynamic or Static Peaks
Change the mode of peak indicators. Dynamic Peaks resets the yellow peak level indicators
to a new peak level after 1.5 seconds, letting you easily see recent peak amplitude. As the audio gets quieter, the peak
indicators recede. Static Peaks retains peak indicators, letting you determine the maximum amplitude of the signal
since monitoring, playback, or recording began. However, you can manually reset peak indicators by clicking clip
indicators.
To find out how loud audio will get before you record it, choose Static Peaks. Then monitor input levels; the peak
indicators show the level of the loudest part.
Adjust recording levels for standard sound cards
Adjust levels if recordings are too quiet (causing unwanted noise) or too loud (causing distortion). To get the best
sounding results, record audio as loud as possible without clipping. When setting recording levels, watch the meters,
and try to keep the loudest peaks in the yellow range below -3
dB
Adobe Audition doesn’t directly control a sound card’s recording levels. For a professional sound card, you adjust
these levels with the mixer application provided with the card (see the card’s documentation for instructions). For a
standard sound card, you use the mixer provided by Windows or Mac
OS.
