Sound Compression is also Possible, in the Time Domain.

One alternative type of sound compression which exists, is ‘FLAC’. This is a method which preserves all the information in the stream (later reproducing it exactly), which uses Linear Predictive Coding, and which Rice-Encodes the Residual, by which actual samples differ from the LPE-predicted values.

When I first tried to understand FLAC, my efforts were lacking, in that I did not know that LPE takes place in the time-domain, and not in the frequency-domain.
