A sound mixer's main responsibility is to mix and balance various audio tracks, including dialogue, music, sound effects, and ambient sounds, to create a cohesive and immersive soundscape for a film.

Synchronization refers to the process of aligning the audio tracks with the corresponding visual elements of a film, ensuring that the sounds match the actions and events on screen.

Foley is a technique used to recreate sound effects in a studio environment, often using everyday objects and props to generate realistic sounds that match the actions on screen.

ADR is used to re-record dialogue in a controlled studio environment, typically to improve the clarity and intelligibility of the original dialogue recorded on set.

Pro Tools is a professional audio editing software widely used in the film industry for its advanced features, such as multitrack editing, mixing, and sound design capabilities.

Fade-in and fade-out are techniques used to gradually increase or decrease the volume of a sound, creating a smooth transition between different audio elements.

Mixing is the process of combining multiple audio tracks, such as dialogue, music, and sound effects, into a single track, adjusting their levels, panning, and effects to create a cohesive soundscape.

Equalization (EQ) is used to adjust the frequency response of a sound, allowing sound editors to boost or cut specific frequency ranges to improve the overall sound quality and clarity.

Reverb is a sound editing technique that adds artificial reverberation to a sound, simulating the natural reverberation that occurs in a physical space, such as a room or a concert hall.

Denoising is the process of removing unwanted noise, such as background hiss, hum, or crackles, from an audio track, improving the overall clarity and quality of the sound.

Normalization is the process of adjusting the overall loudness of an audio track to a standard level, ensuring that it can be played back at a consistent volume across different playback systems.

Compression is a sound editing technique used to reduce the dynamic range of an audio track, making the loud parts quieter and the quiet parts louder, resulting in a more consistent and balanced sound.

Limiting is a sound editing technique used to prevent an audio track from exceeding a certain maximum amplitude, preventing distortion and ensuring that the sound does not become too loud.

Equalization is the process of adjusting the relative levels of different frequency bands in an audio track, allowing sound editors to boost or cut specific frequencies to improve the overall sound quality and clarity.

Panning is a sound editing technique used to position an audio track in the stereo field, allowing sound editors to place sounds in specific locations within the soundscape.
