This discussion of speeding up the music has solved a long-time mystery for
me.   I often play guitar along with the radio, and quite often I've noticed
that songs are slightly out of tune.   Now I realize that bands often don't
record at exactly A-440, but most bands do (with the advent of quartz tuners
this even more so).   Many is the time I've tuned to the radio, and then
replayed the song on the record and it's not in tune.

There are companies that make equipment that digitally records an audio signal
and compresses it (leaves out some samples).   This doesn't cause the key
to shift or timbres to change.   I would thing that most sophisticated
radio stations would use such equipment but I guess most radio stations
are that sophisticated.
