2.3 Loudness normalisation of radio services
Distributors that transmit radio services as well as television services shall apply the same normalisation and alignment process to radio as for television. In that way, loudness inconsistencies are avoided when switching between radio services and also when switching from television to radio mode and vice-versa on a set-top box or similar receiver device. By applying loudness normalisation for radio and television, loudness inconsistency is also solved for operators that use a radio service as an added audio description service to a television programme for visually-impaired people.recommended
