Bitstream versus PCM debate for high-density compact disc, Prof. M.O.J. Hawksford:
The Acoustic Renaissance for Audio (ARA) have proposed [1] a multi-channel, high-resolution audio encoding format for use with the next generation of compact disc with further introductory discussion openly published [2, 3, 4]. The ARA proposal document has already been widely circulated to the audio industry and the following text assumes familiarity with the ARA proposal.
This report is prepared in response to a proposal to import bitstream code directly onto high-density optical discs. Although offering certain philosophical and economic merits we believe that there are fundamental flaws and significant system limitations in using bitstream technology for audio data storage. Specifically, bitstream fails to address the future technical aspirations required by the audio industry where advanced digital processing will be used to improve accuracy in electrical-to-pressure transduction and also three-dimensional sound reproduction. We therefore present a discussion of the reasons for preferring a system based upon PCM rather than bitstream coding ...

Apart from the size and shape of a windscreen, its internal structure has the greatest influence on its efficiency. For maximum attenuation of wind interference it is important to distinguish between the type of protection appropriate to pressure transducers and that which is best for pressure-gradient designs. In the latter case, involving directional microphones, the transducer element should always be surrounded by an enclosed volume, which functions partly as a pressure chamber to cancel such interference.
Wind can be a serious problem for the sound engineer working outdoors. This engineering report will concentrate mainly on the practical aspects of this problem. For those interested in pursuing the matter in greater detail, the references at the end of this text list papers that deal with some fundamental scientific considerations. Scarcely any of these, however, acknowledge the most current technologies, which use foam. Practical applications require that we be fully aware of the different approaches required for the protection of pressure-gradient microphones, as distinct from pressure microphones ...
For some of us in audio, tubes never really went away. We go back to the days when all equipment was tube equipment. (My first job, in the late 1960s, was at a Philadelphia radio station that was 100% "hollow state" from microphone to antenna.) ...
