Lo-fi music, genre of music production in which a recording is intentionally rendered to include imperfections, such as harmonic distortion, background noise, or other anomalous sounds. Such irregularities are normally filtered out of professional recordings, since they generally are undesirable. However, some artists have embraced the limitations of low-quality recording, leveraging imperfections as an artistic choice. The term lo-fi is derived from low fidelity, wherein fidelity refers to sound quality.

Also spelled: lofi music or low-fi music
