Analog signal

An analog signal is a communication method that uses changes in the amplitude or frequency of a continuous radio carrier wave to convey information. The term is often used in comparison with a digital signal. Analog television (and its analog storage mediums) is said to be inferior to today's almost universally used digital television. However, some contest that analog offers better quality.[1]

In the world of audio technology (hi fi specifically), analog never completely lost its popularity, at least amongst hardcore audiophiles. And more so amongst classical music lovers whose enjoyment of a particular recording often could be affected by the ambience of the concert hall; something that went missing in the early days of digitally recorded CDs but has been largely overcome in modern recordings.
