The book gives an extensive up-to-date survey of surround- and stereo-microphone techniques and also - for the first time - offers an answer to the question of why the RCA/BMG "Red Seal" series of legacy recordings from the 1950ies and 60ies is being appreciated by music lovers worldwide despite their use of a seemingly 'wrong' recording technique in sound-engineering/ psychoacoustic terms. In doing so it draws upon knowledge gained through the studying of the acoustics of concert halls, which – being ideal locations for musical performances – should remain the basic reference point on ‘how recordings should sound’, at least according to the opinion of the author … (a point of view which is often discussed among “Tonmeisters”). The five surround microphone techniques which are being looked at in more detail have been analyzed through subjective listening tests with 50 participants, as well as through measuring signal-correlation over frequency. The outcome of the subjective listening test is compared to the objective physical factors measured by means of the correlation function.weiterlesen
