Sound effects (or audio effects) are artificially created or enhanced sounds, or sound processes used to emphasize artistic or other content of films, television shows, live performance, animation, video games, music, or other media. In motion picture and television production, a sound effect is a sound recorded and presented to make a specific storytelling or creative point ''without'' the use of dialogue or music. The term often refers to a process applied to a recording, without necessarily referring to the recording itself. In professional motion picture and television production, dialogue, music, and sound effects recordings are treated as separate elements. Dialogue and music recordings are never referred to as sound effects, even though the processes applied to such as reverberation or flanging effects, often are called "sound effects". == History == The term ''sound effect'' ranges back to the early days of radio. In its Year Book 1931 the BBC published a major article about "The Use of Sound Effects". It considers sounds effect deeply linked with broadcasting and states: "It would be a great mistake to think of them as anologous to punctuation marks and accents in print. They should never be ''inserted'' into a programme already existing. The author of a broadcast play or broadcast construction ought to have used Sound Effects as bricks with which to build, treating them as of equal value with speech and music." It lists six "totally different primary genres of Sound Effect": : * ''The Realistic, Confirmatory Effect'' : * ''The Realistic, Evocative Effect'' : * ''The Symbolic, Evocative Effect'' : * ''The Conventionalised Effect'' : * ''The Impressionistic Effect'' : * ''Music as an Effect'' According to the author, "It is axiomatic that every Sound Effect, to whatever category it belongs, ''must'' register in the listener's mind instantaneously. If it fails to do so its presence could not be justified."〔The BBC Year Book 1931, p. 194ff.〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「sound effect」の詳細全文を読む スポンサード リンク
