.

There are primarily 3 divisions of sound that are combined to create a final mix, these being dialogue, effects, and music. In larger markets such as New York and Los Angeles, sound editors often specialize in only one of these areas, thus a show will have separate dialogue, effects, and music editors. In smaller markets, sound editors are expected to know how to handle it all, often crossing over into the mixing realm as well. Editing effects is likened to creating the sonic world from scratch, while dialogue editing is likened to taking the existing sonic world and fixing it. Dialogue editing is more accurately thought of as "production sound editing", where the editor takes the original sound recorded on the set, and using a variety of techniques, makes the dialogue more understandable, as well as smoother, so the listener doesn't hear the transitions from shot to shot (often the background sounds underneath the words change dramatically from take to take). Among the challenges that effects editors face are creatively adding together various elements to create believable sounds for everything you see on screen, as well as memorizing their sound effects library.

Equipment

The essential piece of equipment used in modern sound editing is the digital audio workstation

. Since the recording is imposed linearly on the medium, and the medium is easily cut and glued, sounds recorded can be easily re-sequenced and separated onto separate tracks, allowing more control in mixing. Options expanded further when optical sound recording processes were replaced with magnetic recording in the 1950s. Magnetic recording offered a better signal-to-noise ratio
Signal-to-noise ratio

 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

  • 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

     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.


Historically the Dubbing Mixer (UK) or Re-Recording Mixer (US) was the specialist who mixed all the audio tracks supplied by the Dubbing Editor (with the addition of 'live sounds' such as Foley) in a special Dubbing Suite. As well as mixing, he would introduce equalization, compression and filtered sound effects, etc. while seated at a large console. Often two or three mixers would sit alongside, each controlling sections of audio, e.g., 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
Noise
In common use, the word noise means any unwanted sound. In both analog and digital electronics, noise is random unwanted perturbation to a wanted signal; it is called noise as a generalisation of the acoustic noise heard when listening to a weak radio transmission with significant electrical 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 workstation

 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
