Abbr. for low-FIDELITY, that is, a system which reproduces less than a full frequency SPECTRUM, and which has a poor SIGNAL-TO-NOISE RATIO. The most general use of the term is in ELECTROACOUSTICs, such as when applied to an AMPLIFIER or recording. See SCHIZOPHONIA for sound examples.
In terms of SOUNDSCAPE studies, the lo-fi environment is one in which signals are overcrowded, resulting in MASKing and lack of clarity.
