Viewing waveform statistics
In Edit View, you can use the Waveform Statistics dialog box to evaluate a variety of infor-
mation about audio amplitude. This dialog box contains two tabs, General and Histogram,
both of which share an RMS Settings section. The General tab displays numerical text boxes
that indicate dynamic range, identify clipped samples, and note any DC offset. The
Histogram tab displays a graph that shows the relative prevalence of each amplitude: The
horizontal ruler measures amplitude in decibels, and the vertical ruler measures preva-
lence using the RMS formula.
Use the Histogram tab to identify prevalent amplitudes, and then compress, limit, or
normalize them with an amplitude effect. (See “Optimizing amplitude” on page 134.)
