Mastering effect
Mastering describes the complete process of optimizing audio files for a particular medium, such as radio, video, CD,
or the web. In Adobe Audition, you can quickly master audio with the Special > Mastering effect.
Before mastering audio, consider the requirements of the destination medium. If the destination is the web, for
example,thefilewilllikelybeplayedovercomputerspeakersthatpoorlyreproducebasssounds.Tocompensate,you
can boost bass frequencies during the equalization stage of the mastering process.
Adobe Audition provides a default workspace that’s optimized for mastering. Choose Window > Workspace >

Mastering options
Equalizer Adjusts the overall tonal balance.
• Graph Shows frequency along the horizontal ruler (x-axis) and amplitude along the vertical ruler (y-axis), with
the curve representing the amplitude change at specific frequencies. Frequencies in the graph range from lowest to
highest in a logarithmic fashion (evenly spaced by octaves).
Drag control points in the graph to visually adjust the settings below.
• Low Shelf and High Shelf Enable Activate shelving filters at either end of the frequency spectrum.
• Peaking Enable Activates a peaking filter in the center of the frequency spectrum.
• Hz Indicates the center frequency of each frequency band.
• dB Indicates the level of each frequency band.
• Q Controls the width of the affected frequency band. Low Q values (up to 3) affect a larger range of frequencies
and are best for overall audio enhancement. High Q values (6–12) affect a very narrow band and are ideal for
removing a particular, problematic frequency, like 60-Hz hum.
Reverb Adds ambience. Drag the Amount slider to change the ratio of original to reverberant sound.
Exciter Exaggerates high-frequency harmonics, adding crispness and clarity. Mode options include Retro for light
distortion, Tape for bright tone, and Tube for quick, dynamic response. Drag the Amount slider to adjust the level of
processing.
Widener Adjusts the stereo image. Drag the Width slider to the left to narrow the image and increase central focus.
Drag the slider to the right to expand the image and enhance spatial placement of individual sounds.
