Focusing Hot Points
After a global analysis, you can focus the display on a specic hot point.
PREREQUISITE
In the Audio Editor, select the Analyze tab, click Global Analysis, and perform the analysis.
PROCEDURE
1. Use the Number of Hot Points scrollbar to move the position indicator to the position in
which you are.
2. Click Focus.
The wave window zooms in on the selected point. The Global Analysis dialog is reduced to
the bottom part.
3. To return to the full view of the Global Analysis dialog, click Focus again.
3D Frequency Analysis
Using the 3D Frequency Analysis, you can view an audio le in the frequency domain.
Use the 3D Frequency Analysis for the following:
Viewing the frequency spectrum distribution in a mix
Identifying which frequencies can be reduced or boosted as a basis for equalizing
Viewing parts of the frequency spectrum that are occupied by a background noise that you
want to lter out
A wave display (time domain) informs you about the start and end of a sound in a le, but lacks
information about the timbral contents of the le that a frequency graph (frequency domain)
provides. The graph that is used in WaveLab Elements is often referred to as an FFT (Fast Fourier
Transform) plot. If you select a stereo recording, a mix of the two channels is analyzed.
The wheel control allows you to view the frequency spectrum from different angles. For example,
you can open several 3D Frequency Analysis windows, each with a different perspective. This
allows you to get a better view of an otherwise crowded graph.
