The greater number of options available to the editors led to more complex and creative sound tracks, and it was in this period that a set of standard practices became established which continued until the [[Digital data|digital]] era, and many of the notional concepts are still at the core of sound design, computerized or not: |

* Sounds are assembled together onto '''tracks'''. Many tracks are mixed together (or "dubbed together") to create a final film. |
|||
* A track will generally contain only one "type" or '''group''' of sound. A track that contains dialogue only contains dialogue, a track that contains [[music]] should only contain music. Many tracks may carry all the sound for one group. |
|||
* Tracks may be mixed a group at a time, in a process called '''predubbing'''. All of the tracks containing dialogue may be mixed at one time, and all of the tracks containing [[Foley artist|foley]] may be mixed at another time. In the process of predubbing, many tracks can be mixed into one. |
|||
* Predubs are mixed together to create a '''final dub'''. On the occasion of the final dub, final decisions about the balance between different groups of sounds are made. |
|||
The '''[[Re-recording mixer|Re-Recording Mixer]]''' ('''Dubbing Mixer''' in the UK) is the specialist who mixes all the audio tracks supplied by the sound editors (including 'live sounds' such as Foley) in a special Re-recording or Dubbing Suite. As well as mixing, he introduces equalization, compression and filtered sound effects, etc. while seated at a large console. Usually two or three mixers sit alongside, each controlling sections of audio, i.e., dialogue, music, effects. |

In the era of optical sound tracks, it was difficult to mix more than eight tracks at once without accumulating excessive [[noise]]. At the height of magnetic recording, 200 tracks or more could be mixed together, aided by [[Dolby]] noise reduction. In the digital era there is no limit. For example, a single predub can exceed a hundred tracks, and the final dub can be the sum of a thousand tracks. |

Digital sound
The mechanical system of sound editing remained unchanged until the early 1990s, when digital audio workstations acquired features sufficient for use in film production, mainly, the ability to synchronize with picture, and the ability to play back many tracks at once with CD-quality fidelity. The quality of 16-bit audio at a 48 kHz sampling rate allowed hundreds of tracks to be mixed together with negligible noise.
The physical manifestation of the work became computerized: sound recordings, and the decisions the editors made in assembling them, were now digitized, and could be versioned, done, undone, and archived instantly and compactly. In the magnetic recording era, sound editors owned trucks to ship their tracks to a mixing stage, and transfers to magnetic film were measured in hundreds of thousands of feet. Once the materials arrived at the stage, a dozen recordists and mix technicians required a half an hour to load the three or four dozen tracks a predub might require. In the digital era, 250 hours of stereo sound, edited and ready to mix, can be transported on a single 160 GB hard drive. As well, this 250 hours of material can be copied in four hours or less, as opposed to the old system, which, predictably, would take 250 hours.
Because of these innovations, sound editors, as of 2005, face the same issues as other computerized, "knowledge-based" professionals, including the loss of work due to outsourcing to cheaper labor markets, and the loss of royalties due to ineffective enforcement of intellectual property rights.
Animation sound editing
In the field of animation, traditionally the sound editors have been given the more prestigious title of "film editor" in screen credits. As animated films are more often than not planned to the frame, the traditional functions of a film editor are often unnecessary. Treg Brown is known to cartoon fans as the sound effects genius of Warner Bros. Animation. Other greats of the field have included Jimmy MacDonald of the Walt Disney Studios, Greg Watson and Don Douglas at Hanna-Barbera, and Joe Siracusa of UPA and various TV cartoon studios.
Other fields
In the production of radio programs and music, persons who manipulate sound recordings are known simply as "editors," in cases where the producers themselves do not perform the task.
