smooths out amplitude differences in the same area, and places the left channel in front.
• Functions identically to the option above, but places the right channel in front.

• 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.

FFT Size menu (Advanced option)
accurate results in terms of frequency (such as the overall frequency estimate), but they also create longer processing
times.
You can generate a step-by-step animation by clicking the Main panel and then holding down the Right Arrow key.
As the cursor scrolls across the across the waveform, Adobe Audition displays the corresponding spectral infor-
mation in the Frequency Analysis panel.
Note: When you set the FFT size to 8192 or lower, the Frequency Analysis panel updates in real time while you play a
file. (Keep in mind that how well it ultimately updates in real time is based on the computer's speed.)
FFT Window Type menu (Advanced option)
slightly different kind of frequency graph.
The Triangular option gives a more precise frequency estimate, but it's also the noisiest, meaning that other
frequencies will be shown as present, even though they may be much lower in volume.
At the other extreme, the Blackmann-Harris option displays a broader frequency band, which isn't as precise, but the
sidelobes are very low, making it easier to pick out the major frequency components.
Reference (Advanced option)
example, a value of zero displays 0 dBFS audio at 0 dB. A value of 30 displays 0 dBFS audio at –30 dB. This value
simply moves the display up or down; it does not change the amplitude of audio data.
Copy To Clipboard (Advanced option)

Zoom phase and frequency graphs
In the Phase Analysis and Frequency Analysis panels, you can zoom graphs to analyze phase and frequency in more
detail.

Do any of the following:
• To zoom in on a graph, right-click and drag the magnifying glass icon in the vertical or horizontal ruler. (In the
Phase Analysis panel, you can also click in the panel and use the mouse wheel to zoom.)
• To navigate a magnified graph, left-click and drag the hand icon
• To zoom out on a magnified graph, right-click in the vertical or horizontal ruler, and choose Zoom Out or Zoom
Out Full. Zoom Out to return to the previous magnification. (This option is available only in the Frequency
Analysis panel.) Zoom Out Full to zoom out completely.
