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.
In some cases high fidelity recording is avoided, or the artifacts are deliberately retained or added to all or part of the recording for artistic reasons. This decision is usually made by the record producer. Some argue certain unique aural qualities are available only with "low-tech" recording means.
Examples of lo-fi-type sounds include recordings of vinyl crackles on compact discs, as on Portishead's album Dummy, and telephonic vocals on Craig David's track "Fill Me In" (though these two are not regarded as "lo-fi" bands).
Lo-fi website/or webpage/or forum
A "Lo-fi" website (Low Fidelity) can also be a website with very simple architecture. In general, it is a copy of the main website and often designed for people who have an old computer with/or a slower Internet connection (notably 56K connections). Users can often access the main website from a link at the bottom of the page.
Lo-fi wireless connectivity
A "Lo-fi" wireless connection also refers to the process by which unprotected ethernet wireless (802.11) access point (AP's) are mapped and labeled for unrestricted use by anyone. A "lo-fi" site is first logged, then labeled or mapped so that another person with a (laptop) computer with and a wireless network adapter can get onto the internet to retrieve websites, email, or otherwise use the provided internet connection without advance or prior authorization, and without any trace or fees. In general, access point wireless ethernet hardware come configured with "default" settings, and therefore are not protected against unauthorized use. Many people install their new access points or wireless routers to their internet service provider modem, without changing these default security settings, making it possible for anyone with a properly configured system to connect to and use the provider's internet connectivity, with or without prior authorization. The name "Lo-Fi" is symbolic as an independent and "Low cost" (free except for the price of equipment) version of the "Wi-Fi" system, which was promulgated by the Wi-Fi Alliance *, a non-profit organization with the goal of driving the adoption of a single worldwide-accepted standard for high-speed wireless local area networking.
