Production sound mixer

Usually, the recordist will arrive on location with their own equipment, which normally includes microphones, radio systems, booms, mixing desk, audio storage, headphones, cables, tools, and a paper or computer sound logs.

The recordist may be asked to capture a wide variety of wild sound on location, and must also consider the format of the finished product (mono, stereo or multi channels).

Larger productions will often take advantage of a sound stage, or a large prepared environment that has been treated for acoustic control and is attended by an audio staff, directed by the mixer.

[1] The recorded production soundtrack is later combined with other elements, i.e. effects, music, narration, Foley or re-recorded dialog by automated dialogue replacement (ADR).

Often, when taping on video, the sound recordist may record (single system) audio directly onto the camera rather than use a separate medium (double system), although a separate copy is often made, as it both provides an extra copy which may have more tracks and also may include other sound captured without the camera.
