Leads the entire sound post-production, coordinating all sound editors and taking responsibility for the final sound design.
Technical Details
The Supervising Sound Editor works with Digital Audio Workstations (DAWs) such as Pro Tools HDX systems with up to 768 voices at 48 kHz/24-bit. They structure projects into standardized track groups: Dialogue (16-32 tracks), ADR (8-16 tracks), Foley (24-48 tracks), Sound Effects (100-400 tracks), and Ambiences (20-60 tracks). Workstations are equipped with calibrated near-field monitors at 83 dB SPL with pink noise and surround monitoring up to 7.1.4 Dolby Atmos. Typical project sizes range from 50-200 GB for a 90-minute feature film.
History & Development
The position originated in 1977 with Ben Burtt's work on "Star Wars," when a sound designer first took overall responsibility for all sound elements except music. Previously, the Sound Effects Editor and Dialogue Editor shared these tasks equally. In 1981, the Motion Picture Sound Editors Guild introduced the official job title. Digitalization from 1990 onwards, with systems like Sonic Solutions, significantly expanded creative control. Since 2010, object-based audio like Dolby Atmos requires additional expertise in three-dimensional sound positioning.
Practical Application in Film
For "Cast Away" (2000), Supervising Sound Editor Randy Thom structured the 90-minute island sequence without dialogue through 127 precisely layered natural ambiences. For "Dunkirk" (2017), Richard King coordinated 340 tracks with practical aircraft and ship recordings captured simultaneously on location with 32 microphones. The workflow begins with the locked cut, involves 8-12 weeks of editing, and concludes with pre-dub preparation in stems-separated premixes.
Comparison & Alternatives
Unlike the Sound Designer, who primarily develops new soundscapes, the Supervising Sound Editor focuses on technical implementation and team leadership. The Re-Recording Mixer only becomes involved during the final mix, while Post Production Supervisors coordinate all departments. For budgets under €500,000, a Sound Editor often handles both functions. Streaming productions additionally require expertise in Dialogue Intelligence and loudness standards like EBU R128 (-23 LUFS).
