Enhancing and Restoring Audio
Hold buttons Take up to four frequency snapshots as a waveform is playing. The frequency
outline (which is rendered in the same color as the button clicked) is frozen on the graph and
overlaid on other frequency outlines. Up to four frozen frequency outlines may be shown at
once. To clear a frozen frequency outline, click its corresponding Hold button again.
Status areas Display frequency and amplitude information directly underneath the
graph. The left status area displays the highest frequency of the entire waveform and the
maximum amplitude for each channel. The right status area displays the overall frequency
(and equivalent musical note) at the center point of the selected range. The numbers
beside musical notes indicate keyboard position and variance from standard tuning. For
example, A2 +7 equals the second-lowest A on a keyboard tuned 7% higher than normal.
By default, the musical note of the left channel also appears at the top of the window.
To hide that note, dock the window, right-click the window handle, and deselect Show
Big Notes. For more information, see “Using windows” on page 14.
Display style menu Select from the following graph display options:
• Lines displays amplitude at each frequency with simple lines. The left channel is blue;
the right is red.
• Area (Left On Top) also displays lines for amplitude, but this option fills the area
beneath the lines in a solid color, smooths out amplitude differences in the same area,
and places the left channel in front.
• Area (Right On Top) functions identically to the option above, but places the right
channel in front.
• Bars (Left On Top) shows the limitations on analysis resolution by splitting the display
into rectangular segments, and places the left channel in front. The higher the FFT size,
the greater the analysis resolution, and the narrower the bar.
• Bars (Right On Top) functions identically to the option above but places the right
channel in front.
Scan Click this button to scan the highlighted selection and show all frequencies present
in that selection.
By default, Adobe Audition analyzes only the center point of a selected range. To analyze
the overall frequency of a selected range, click Scan.
