Audio

High fidelity is the high-quality reproduction of sound, popular with audiophiles and home audio enthusiasts. Ideally, high-fidelity equipment has inaudible noise and distortion, and a flat, uncolored frequency response within the human hearing range, which contrasts with the lower-quality lo-fi sound of inexpensive audio equipment, AM radio, or recordings made until the late 1940s. Listeners proved to prefer high-fidelity reproduction once the noise and distortion introduced by early sound equipment was removed. Source
