Lo-fi (from the term "Low fidelity") is a term used to describe music in which the sound is of a lower quality than the usual standard. The qualities of lo-fi are usually achieved by either degrading the quality of the recorded audio, or using certain equipment. Recent uses of the phrase have led to it becoming a genre, although it still remains as an aesthetic in music recording practice. Many lo-fi artists use inexpensive cassette tape recorders. The term was adopted by WFMU DJ William Berger who dedicated a half hour segment of his program to home recorded music throughout the late '80s under the name Lo-fi.(wikipedia)
