Naturally, some of the Inspector playback parameters (such as Transposition) that can be
applied to MIDI events have no effect on audio signals. Equivalent operations for most
of these are available as destructive edit operations in the Sample Editor.

The fundamental functions (such as a freely determinable position and length, the ability
to create complex arrangements with the aid of folders, and the ability to name, mute,
and solo) are generally available to all types of regions (MIDI regions, audio regions, folder
regions, or copies of these, and alias or cloned regions).

Handling Regions in the Audio Bin and Sample Editor

You can use the Audio Bin to manage your regions and to make rough edits to the region
(or regions) associated with an audio file. The graphic display in the Audio Bin is optimized
for quick and simple organization of audio files and regions.

The finest resolution for positioning the region start and end markers, or the anchor, is
limited to 256 sample steps in the Audio Bin. This is usually adequate, particularly if Edit
> Snap Edits to Zero Crossings is turned on.

On occasion, however, you will need to make very accurate adjustments—down to the
individual sample word level. Drum loops are a good example. The Sample Editor is
best-suited to these types of precision editing tasks.

To open the Sample Editor for a particular region

Double-click the region in the Audio Bin or Arrange area.
