Document Summary
Segments time and thus loses elements of real sound. With high enough sampling rate, could have better sound than lp: increased bandwidth, better signal-to-noise ratio, less distortion. More durable: less susceptible to scratches and surface noise . Programmable play (immediate access to different tracks) Perceptual coding": uses a mathematical model of human psychoacoustic response to throw out any portion of a signal that listeners are unlikely to hear. The mp3 is designed for easy exchange, easy storage and maximum portability. (sterne) Mass file sharing: easier to duplicate and transmit. Fidelity is similarity to original (sterne: impossible and wrong question to ask, e. g. many performances staged for recording) E. g. audio compression (not data compression) - increase overall volume by reducing range (less distance between quietest and loudest sounds), aka loudness maximization. Beyond recording studios and living rooms, there are relatively few environments where people can hear the edges of a recording"s definition.
