Define what you mean by 'compressed audio' I don't think you

Audio compressed using perceptual audio codecs.

Thanks for confirming you have no idea what audio compression is.


There are two forms of "audio compression" - one is dynamic range
compression, and the other is data compression.

Most consider audio to be just that. Data something else. But if you
actually understood the original point it would be obvious it
applied to
dynamic range alteration.

The latter is what I'd
always consider to be "audio compression", and I'd expect the
former
to be called by its full name or be called "audio processing" or
just
"processing".

Audio compression dates back to long before digits were thought of.
Or
certainly before digital audio was practical.

FWIW true audio compression is a loss less method. It can (in
theory) be
recovered to the original by using the reverse algorithm. Such an
application was reducing noise over a link or recording, etc.

Digital compression is quite the reverse - it generally involves
throwing
away information. And should never have been allowed to adopted this
term.


Never heard of lossless audio compression then? Try Googling for FLAC.

The adoption of DAB was the most incompetent technical
decision ever made in the history of UK broadcasting:
