Colouring

An effect describing the influence of a location, electroacoustic system, or instrument on the new balance of the frequencies of a sound, "coloured" through its diffusion. We speak of the "colour" of a room or the "colour" of a loudspeaker. Colouring is acoustically linked to filtration, but its use remains more popular. To the untrained ear, the colouring of a sound situation is particularly well perceived when colouration changes rapidly. A good example is the clear inside/outside transition of film soundtracks or the entry of woodwind instruments (flute, clarinet, bassoon, oboe) in the musical stream of string instruments.
