B. montage is the term used to describe the process of mixing sounds from multiple sources in a sound editor. In a montage, the sound editor combines sounds that may have different qualities, levels, and placements in order to create a cohesive and harmonious audio experience. This process can involve a variety of techniques, such as equalization, panning, and reverb, to create the desired effect. Montages are commonly used in film and television productions to create complex and immersive soundscapes.
