Low fidelity or lo-fi describes a sound recording which contains accidental artifacts, such as distortion or environmental noise, or a recording which has a limited frequency response. This stands in contrast to high fidelity or "hi-fi".

In digital audio lo-fi usually refers to an audio file with a lower bit rate or sampling rate, and thus a lower sound quality.
