Isn't this (mutatis mutandis) what MP3 compression does ? Actually, MP3
use a cosine transform,<br>
not an FFT, but conceptually there are not many differences. When you

what you send are the coefficients of the cosine transform, which are
then used during playback to <br>
reconstruct the analog version of your favorite musical performance.<br>
