It can, however, perceive the frequencies. Impulses get rounded off a
lot in audio recordings, and that makes them quite useless for many
engineering applications as well as people with ears.
I'd be looking at the multimedia modes of things like 7zip and other
high-end compression programs. The other approach is brutal - cut the
bit rate by dropping bits per sample. You get more noise but you might
be surprised how similar the output is even at 1bps.
