Room-acoustical and Technological Aspects for Mulichannel Recordings of Classic Music

The more the quality increases on the part of studio engineering - i.e. microphones, pick-up technology, delivery, storage - the more some weakness is evident at the beginning and the end of the transmission chain: (a) Recording studios for classical music mostly have not the required quality parameters for the artists and the information to be recorded. A sone recommandable example the large recording hall in Berlin and its charcteristic are discussed. Experiences with multichannel sound productions in this hall are covered. (b) On the other side, standard listening conditions of control rooms - see AES document TD 1001.0.01-05 'Multichannel surround sound systems' - have to be considered from time to time to show open questions and the uncertain situation at home.
