Whether in the studio or in the field a microphone may be placed in close proximity to the physical source of a sound. Close-mic recording is common in electroacoustic practice since it allows for the capture of rich spectral detail that may serve an important function in the signifying potential of musical material or the investigation and manipulation of this detail as a structuring principle in the studio. Analogies could be made with macro-photography, close-up shots, or the microscope. Since there is very little distance between microphone and the cause of a sound, close-mic recordings will generally reveal little information as to the acoustic environment in which the recording was created, which may be deemed an advantage if material is to undergo later transformation or signal processing.
