BBC Research & Development Report (page 8):

'[DAB uses the MPEG Layer II audio codec]. This offers a variety of options, in which bit-rate can be traded for quality. For high quality stereo signals, a bit-rate between 192 and 256 kbit/s is needed.'

Currently, 98% of stereo stations on DAB in the UK use a bit rate of 128kbps and Ofcom have even proposed to drop the this minimum bit rate to 112kbps!
