High-Fidelity Sound

1. The frequency range of the reproduced sound should be sufficient to retain all the audible components in the source sound, and the sound spectrum of the reproduced sound should be identical to that of the source.

2.  The reproduced sound should be free of distortion and noise.

3.  The reproduced sound should have loudness and dynamic range comparable to the original sound.

4.  The spatial sound pattern of the original sound should be reproduced.

5.  The reverberation characteristics (in space and time) of the original sound should be preserved in the reproduced sound.
