Audio Regions

Fluctus Main View

Rearrange Regions

An unlocked region can be freely moved within the workspace (also see Snap to).

When two regions overlap, the Bring to Front or Send to Back functions can be used to see the region of interest.

These options are also available from the region contextual menu and from the Region Finder.

Region Resizing

Fluctus Region Resizing

When unlocked, region bounds can be changed by dragging and dropping the lower corners to a new place (also see Snap to).

We can also trim the region with the Trim to Selection action.

Region Fades

Fluctus Region Fades

All audio regions have a configurable fade-in and fade-out function.

Drag and drop the squares on the top corners to set the fade size (also see Snap to).

Furthermore, four types of fade can be set from the region-fade contextual menu or from the Region Inspector.

Fade Types:

Linear, S-Curve, Concave-Curve and Convex-Curve.

Region State

Fluctus Region Icons

All regions display some basic clues about their current state.

When a region is Locked, Muted or Phase Reversed, an icon will appear to remind the user about its state.

This feature is especially useful if there is a number of concurrent regions sharing the same workspace.

Region Split

Fluctus Region Split

Regions can be splited with the Split Tool or with the Split at Selection action.

Advanced Split

Fluctus Advanced Split

When you right-click a Region, you will be presented with extra Split functions.

Note: the options available are determined by the Region type.

Region Transform

Fluctus Region Transform

When you right-click a Region, you will be presented with in-place transform options.

Note: the options available are determined by the Region type.

Region Inspector

Fluctus Region Inspector


Ticking this box will lock the region in place, preventing unwanted changes.

Draw Waveform

Unticking this box will hide the region Waveform, therefore reducing CPU usage.

Fade-in and Fade-out

Refer to Region Fades.

Spectrogram (Fluctus Expert Only)

Depending on the version being used, you will find a Spectrogram section.

Ticking the "Show on Region Box", will replace the Waveform with a Spectrogram.

The Spectrogram can also be configured with a linear/logarithmic scale and mono/polychromatic colouring.


The Audio section gives access to basic audio mixing utilities.

Regions can be individually muted, phase reversed, panned and gain shifted.

For mono regions, the Channel Assign option will be active, and you can assign the playback to one of the available channels.

When the Channel Assign option is different than Off, the Stereo Pan will be disabled.
