BIT RATE: DAB allows broadcasters to vary the BIT
RATE (or the amount by which an audio signal can be
compressed) depending on the type of broadcast. This
enables the amount of stations on a multiplex to be
maximised. Speech and News are often broadcast at a
lower Bit Rate; music needs a higher Bit Rate for good
delity.
