Since DAB uses compression similar to how MP3 works, there are a heck of a
load more variables involved that just the frequency response that
determines audio quality. A music channel will have a frequency response
similar to FM (50 Hz to 16kHz) but a speech channel will cut off circa
6kHz IE similar to AM bandwidth.
