Zoom In

Zooms in on the horizontal axis of the audio, displaying more detail about less time. You can also use the zoom tool to zoom in on a particular part of the window.

Zoom Normal

Zooms to the default view, which displays about one inch per second.

Zoom Out

Zooms out, displaying less detail about more time.

Fit in Window

Zooms out until the entire project just fits in the window.

History

Brings up the history window. It shows all the actions you have performed during the current session, including importing. The right-hand column shows the amount of HD space your operations used. You can jump back and forth between editing steps quite easily by simply clicking on the entries in the window.

The history window can be kept open at all times. It doesn't interfere with any other operations.

Plot Spectrum

To use this feature, first select a region of audio from a single track, then select "Plot Spectrum".

It opens up a window which displays the Power Spectrum of the audio over that region, calculated using the Fast Fourier Transform. The graph represents how much energy is in each frequency.

This window can also display other common functions that are calculated using the Fast Fourier Transform, including three versions of the Autocorrelation function.

The Enhanced Autocorrelation function is very good at identifying the pitch of a note.

Float of Unfloat Palette

Toggles between displaying the tool palette docked at the top of each project window, or in a separate floating window. You can also float the tool palette by grabbing the handle on the left side and dragging it to the location you want.
