For decades, the Oscars honored movie sound twice. One race saluted the people who built the sounds. The other saluted the people who balanced them. Viewers mixed up the two categories constantly, and no wonder. The names sound alike, the credits blur, and the crafts overlap.
The split makes sense once you see how a soundtrack gets made. First, sounds are gathered and shaped. Then they are blended into one track. Those are two different jobs, and the Academy treated them as such for years. This connects to our earlier piece, How the Academy's Preferential Ballot Actually Picks the Best Picture Winner.
One Craft, Two Categories
According to Wikipedia, competitive awards for sound ran as two separate categories from 1963 to 1967 and again from 1982 to 2019 . One was Best Sound Mixing. The other was Best Sound Effects Editing, later known simply as Best Sound Editing.
The sound honor itself is much older, and it once went to studio sound departments instead of people. A rule change in 1969 redirected it to specific technicians. Wikipedia credits Murray Spivack and Jack Solomon as the first so honored, winning for "Hello, Dolly!"
What Sound Editors Build
Sound editing is construction. Wikipedia describes the sound editor as the professional who selects and assembles sound recordings to prepare for the final mix. The work falls into three divisions: dialogue, effects, and music . In large markets, editors specialize in one division each, so a production may carry separate dialogue, effects, and music editors.
The craft began as repair work. Early talkies delivered incomplete, undramatic, or technically poor recordings, and editors patched them. Over the decades the job grew into a creative art. Effects editors build a sonic world from scratch. Dialogue editors clean the sound captured on set so lines flow smoothly from shot to shot.
The tools changed the speed of the work. Modern editors use digital audio workstations, software that stores sounds as computer files and lines them up against the picture, according to Wikipedia. A whole reel of sound can now be rebuilt in an afternoon.
Some stock sounds become famous on their own. The Wilhelm scream, a recording named and popularized by sound designer Ben Burtt, turns up in films from "The Empire Strikes Back" to "Raiders of the Lost Ark," according to Wikipedia.
What Sound Mixers Balance
Mixing is judgment. Wikipedia defines a re-recording mixer as the engineer who mixes recorded dialogue, effects, and music into the final soundtrack . In Europe the same job is called a dubbing mixer. The process starts with premixes, where each group of tracks gets its first polish. The final mix follows.
The tracks arrive sorted. Editors keep each type of sound on its own set of tracks. Mixers often blend one group at a time first, a pass Wikipedia calls predubbing. The last session, the final dub, then balances every group against the rest.
In that last pass, mixers decide moment by moment how loud each element should be. The footsteps, the score, and the whispered line all compete for space. The director guides the choices. The mixer decides what the audience hears first.
Why the Split Mattered
The two races let the Academy honor both halves of the craft. A film could win for building a world of sound, for balancing it, or for both. A double win became a badge of honor for a sound team.
Today the Academy presents a single Best Sound award instead. According to Wikipedia, it now recognizes sound mixing, recording, sound design, and sound editing together. The two crafts still exist. The ballot just stopped separating them. Readers following this should also see Awards Won by Sandra Hüller: Europe's Breakout Contender, From Festival Floors to the Oscar Ballot.
Conclusion
Sound editing builds the pieces. Sound mixing arranges them. The old two-category split tracked that division of labor, even if it confused everyone watching at home.
So when an Oscar goes for sound, remember the two crafts behind it. Someone made every sound you hear. Someone else decided how loud it should be.
