What is a Sound Editor?

A sound editor is a post-production professional responsible for the entire soundscape of a film, TV show, advertisement, video game, or other audiovisual media. Their primary role is to edit, enhance, and assemble all of the sound elements to match the visual components and support the storytelling.

The job of a sound editor encompasses a wide range of audio-related tasks. Some of their key responsibilities include:

  • Editing and cleaning up dialogue recordings to improve clarity, flow, and sync with pictures. This involves cutting unwanted sounds like background noise or room tone and making dialogue sound seamless between edits.
  • Creating and editing Foley sound effects that match on-screen movements and actions. Foley artists record sounds like footsteps, clothing rustles, and object handling in sync with the video, while sound editors refine these recordings.
  • Designing and assembling background ambiances to establish locations and environments. This includes room tones as well as outdoor atmospheres.
  • Selecting and editing hard effects like doors opening and closing, glass breaking, gunshots, etc. These are sourced from sound libraries.
  • Adding enhancements like reverb and EQ to situate sounds in spaces and make them fit together cohesively.
  • Ensuring all audio elements are at appropriate levels and balanced in the mix.
  • Working closely with composers and music supervisors to edit score elements around dialogue and effects.

The expertise of a professional sound editor is critical for bringing all the disparate audio components together into a unified sonic experience that supports the storytelling and immerses the audience. Their technical skills and artistic sensibilities are what transform raw audio into the vivid and emotive soundscapes we experience in films, TV, games, and other media. Quality sound editing can make or break a project.

What Does a Sound Editor Do?

The sound editor’s job encompasses a diverse range of sound department skills and tasks that all contribute to the final soundscape.

Roles and Responsibilities of a Sound Editor

A sound editor’s main duty is to assemble, edit, and help mix all the audio elements in a project. This is a complex job that requires both technical chops and creative talent. They work closely with the supervising sound editor to ensure all tasks are completed.

Some key tasks sound editors handle include:

Creating Sound Effects

Sound editors are responsible for creating or curating all of the sound effects that help bring the visuals to life. This includes hard effects like gunshots, explosions, crashes, etc., as well as ambient backgrounds or “atmospheres” like city streets, jungle wildlife, or the hum of a spaceship. They build these sounds from scratch with a sound designer or source them from comprehensive sound libraries.

Working with Foley Artists

Foley artists record specialized sound effects in sync with the picture to capture subtle sounds like footsteps, cloth movement, handling props, and other scene details. Sound editors then take these sounds and edit them to match the timing and perspective of the visuals.

Synchronizing Sound and Visuals

A crucial task is making sure all the various dialogue tracks, sound effects, foley, and music line up precisely with the action on screen. Even minute delays can be perceptible, so sound editors zoom in frame-by-frame to fine-tune sync.

Editing Dialogue and Other Audio Elements

Recording production dialogue results in lots of unwanted background noise, inconsistencies in volume and tone, and miscues. Sound editors carefully edit this recorded dialogue, to clean it up, polish it, and make it flow smoothly.

Working with Music

The sound editor collaborates with the composer and music editor to edit and balance score elements with dialogue and effects. This includes the mixing process and editing musical hits to picture.

Working with the Sound Mixer

The sound editor collaborates closely with the production sound mixer, who records dialogue and ambient sound on set. They ensure all the sound tracks are cleanly captured and provide notes for improvements during the sound mix.

The sound editor oversees all these tasks from start to finish. They maintain constant communication with the director to achieve the intended creative vision. It’s a meticulous job that requires sharp ears, technical skills, and creative problem-solving. The sound editor’s hard work assembling all the pieces provides an engaging and believable final soundtrack.

Common Tools for Sound Editors

Sound editors rely on a range of equipment, software, and libraries of sound effects to accomplish their work. Having the right tools is crucial for enhancing productivity and efficiency when working on complex audio projects.


Some standard pieces of equipment found in most sound editing studios include:

  • High-quality studio reference monitors for accurate audio playback
  • Fast external storage drives for session files and sound libraries
  • Midi keyboard controller for performance input
  • High-quality headphones for detailed audio editing
  • Audio interface with multiple inputs and outputs
  • Acoustic treatment for the edit suite to optimize the listening environment

Sound editors work with digital audio workstation (DAW) software to complete most of their tasks. Here are some of the most popular DAWs available:

  • Pro Tools – The industry standard digital audio workstation for sound editing, mixing, and more.
  • Nuendo – Advanced tools for editing dialogue, music, sound effects, and more.
  • Reaper – Another solid performer with a large group of users.
  • Adobe Audition – Powerful audio editing and restoration software.

Additionally, they employ specialized plugins for audio restoration, EQ, dynamics, reverb, and more.

Sound Effects Library

Sound editors rely on comprehensive libraries containing thousands of high-quality sound effects to source from. These can be general collections or specific to genres like sci-fi or horror. Editors build their own libraries over time as well.

Having a well-equipped studio with the essential gear, software tools, and sound library gives sound editors the resources they need to work efficiently and deliver polished results on tight deadlines. The right tools are a core part of the job.

Responsibilities of a Sound Editor

While sound editors perform a wide array of technical and creative audio tasks, they also hold some key high-level responsibilities that are critical to the overall success of the sound team on a project.

Ensuring Clarity of Audio

One of the most important responsibilities of a sound editor is to ensure that all the dialogue and important sound effects are clear, audible, and intelligible. They fix issues in production audio and reduce or eliminate distracting background sounds and noises. The audience needs to be able to understand the story being told.

Completing Editing Tasks

Sound editors are responsible for supervising sound and for completing all audio editing, processing, and assembly tasks on schedule according to the post-production timeline. The editing tasks are complex and require time and dedication to get right. Sound editors need to manage their workload to deliver on time.

Working Closely With Directors and Producers

Since audio is a key part of the audience experience, sound editors need to collaborate with directors and producers to understand the creative vision for the soundscape. They translate these creative directions into technical execution. Clear communication ensures the audio supports the storytelling.

At a high level, sound editors must have great technical competence, time management abilities, and creative collaboration skills. Their responsibilities directly impact the cohesion of the final product. Skilled sound editing brings all the audio elements together with the visuals to create an immersive experience.

Benefits of Working with a Professional Sound Editor

While it may seem like an added expense, hiring a seasoned sound editor for your film, TV show, or other media project provides significant benefits that can elevate the final product.

  • Enhanced Audio Quality – Experienced sound editors have the skills to take production audio and transform it into polished, clear, dynamic soundtracks using professional equipment and techniques. This greatly enhances the listening experience.
