Everything about Audio Editing totally explained
Audio editing is the process of taking recorded sound and changing it directly on the
recording medium (analog) or in
RAM (digital).
Audio editing was a new technology that developed in the middle part of the
20th century with the advent of
magnetic tape recording. Prior to magnetic tape, editing (and the repairing of breaks) was performed on wire recorders with solder and extra wire to reinforce the new joint. After
World War II, reel-to-reel tape machines became prevalent and edits were made with straight razors and "splicing" tape to connect pieces of magnetic tape that had been cut. Audio editors would listen to recorded tapes at low speeds, and then located specific sounds using a process called
scrubbing, which is the slow rocking back and forth of the
tape reels across the playback heads of the
tape deck.
With the development of
microcomputer technology, sound recordists were able to
digitize their recordings and edit them as
files within a computer's
RAM. The earliest audio editor was written by
Soundstream Inc specifically for the
PDP-11 minicomputer platform.
Digital audio workstations appeared using proprietary software and hardware solutions but after the
personal computer became widely available in the mid '80s, much the power of a DAW came into the hands of home and small business users through software audio editing programs written specifically for personal computers. The earliest program to become widely used in this application was a
wave editor called
Sound Designer in the late
1980s and early
1990s. Sound Designer was created by a company called
Digidesign who achieved early industry dominance. Today, the most popular retail audio editing programs not associated with specific hardware are:
Audacity,
Adobe Audition,
Sound Forge,
Samplitude,
Adobe Soundbooth and
Goldwave.
In recent years, with the growing popularity of
GNU/Linux, a number of
Open Source software projects have sprung up in order to develop an open source audio editing program. This movement has been bolstered recently by the development of
ALSA, and the Linux low latency kernel patch, which allow the GNU/Linux Operating System to achieve audio processing performance equal to that of commercial operating systems. The multi-platform package
Audacity is currently the most fully-featured free software audio editor.
