Lo-fi

Low fidelity (commonly known as lo-fi, also typeset as lofi or low-fi) is a music or production quality in which elements usually regarded as imperfections in the context of a recording or performance are present, sometimes as a deliberate stylistic choice. The standards of sound quality/ fidelity and music production have evolved over the decades, meaning that some older examples of lo-fi may not have been originally recognized as such. Lo-fi began to be recognized as a style of popular music in the 1990s, when it became alternately referred to as DIY music (from "do it yourself"). Some subsets of lo-fi music have become popular for their perceived nostalgic or relaxing qualities, which originate from the imperfections that define the genre.
