Chapter 2: Pro Tools Concepts
Before you begin to use Pro Tools, you may find it
helpful to review Pro Tools concepts. These con-
cepts are the foundation of Pro Tools operation
and functionality.
Hard Disk Audio Recording
Hard disk recording is a nonlinear (or random ac-
cess) medium—you can go immediately to any
spot in a recording without having to rewind or fast
forward.
This differs from tape-based recording, which is a
linear medium—where you need to rewind or fast
forward to hear a particular spot in a recording. To
rearrange or repeat material in a linear system, you
need to re-record it, or cut and splice it.
Nonlinear systems have several advantages. You
can easily rearrange or repeat parts of a recording
by making the hard disk read parts of the recording
in a different order or multiple times. In addition,
this re-arrangement is nondestructive, meaning
that the original recorded material is not altered.
Pro Tools Nonlinear Editing
Pro Tools is a nonlinear recording editing system
that lets you rearrange and mix recorded material
nondestructively. Nonlinear editing simply means
that you can cut, copy, paste, move, delete, trim,
and otherwise rearrange any audio, MIDI, or video
in the Pro Tools Edit window.
Nonlinear editing provides significant advantages
over dubbing (re-recording), and cutting and splic-
ing magnetic tape. It gives you the greatest possi-
ble flexibility for editing and arranging, and it is all
nondestructive and “undoable.” Additionally, with
nonlinear editing in Pro Tools, you will never in-
troduce any degradation of audio fidelity as you
would with tape.
