SOUND
FOR FILM

Sound shapes how a film is felt as much as how it is heard. From dialogue and Foley to world building, sound design and the final mix, every layer helps define place, perspective, movement and emotion.
Sound for Film breaks down the key stages of post-production audio, what they actually do, and how Hatiwave approaches each one.
Every stage of sound post-production has a different job to do. From restoring dialogue and building the world around the picture to shaping music, effects and the final mix, each stage helps guide what the audience hears, notices and feels. Select a section below to see how Hatiwave approaches each part of the process.
DIALOGUE & ADR
Dialogue is usually the first thing we work on because if the audience is struggling to understand what’s being said, everything else becomes secondary.
We clean production dialogue using tools such as iZotope RX and CEDAR to reduce things like clothing rustle, wind, hum, mouth clicks, mic bumps, broadband noise and other unwanted sounds picked up during filming. We’ll also balance dialogue between takes and scenes so voices feel natural rather than heavily processed.
There are limits though. A recording made directly next to a generator, badly clipped audio, heavy digital crackling or dialogue buried under another loud source can sometimes be improved massively, but pushing restoration too far starts taking parts of the voice away with it. We’d rather leave a little natural background than give you dialogue that sounds metallic and over-processed.
Where something genuinely can’t be repaired, ADR is another option. That can be anything from replacing a single damaged word to rebuilding an entire scene, then matching the new recording back into the location so it doesn’t suddenly sound like somebody stepped into a vocal booth halfway through the film.
We’ll always try to preserve the original performance first.
