  • Abstract
    Attention is called to the principal difference between the present success of audible pictures and the failures which preceded it. The similarities and differences between broadcasting and audible pictures are pointed out. This includes a comparison of the installations, a comparison of the pickup and reproduction conditions, etc. Some of the advantages of disk recording are pointed out. Measurements of the acoustical characteristics of recording stages and theaters are given, as well as system frequency characteristics. The factors limiting the frequency range on disk recording are discussed. Some of the problems in sound editing are mentioned and the elements in greatest need of improvement are pointed out.
