Default NICAM vs DVB vs DAB (original design)

Pros and cons of NICAM vs DVB vs DAB (original design)


DVB (aka AAC)
-- Codec complexity, coding time
-- Ogg Vorbis may have a better FFT

DAB (Musicam)
-- Not as efficient as AAC
-- FFT and filterbank perhaps too simple
-- Does not support 24 bit audio, only 16 bits

Still, if one were designing a DAB system in the mid-1980s ... NICAM is near
perfect.
-- IF AND ONLY IF "RDS" datastream is added


DAB and DVB both use the MPEG1 level 2 compression (Musicam)

Only DAB+ uses AAC+
