Phase 4 Stereo was a recording process created by the U. Decca Records label in Decca recordings and also those of its American subsidiary London Records during the s. Phase 4 Stereo recordings were created with an innovative channel, and later channel, "recording console"  actually a mixing console. The concept of Phase 4 Stereo has no connection with Quadraphonic sound or "four channel stereo. Approximately two hundred albums were released with the process, including popular music"gimmick" records engineered to make the sound travel from speaker to speaker, records featuring percussion effects, and historical sound effect records.
Ina light classical Phase 4 "Concert Series" was produced. A space themed version, An Astromusical Odysseywas arranged by Johnny Keating which included songs from the late s to the early s. A selection can be heard on YouTube . By the end of the s Decca had consolidated a remarkable prestige among music lovers in the field of high-fidelity music recording through its ffrr full frequency range recording series.
These recordings took advantage of the technological advances developed by the firm during World War II at the request of the Royal Navy. In the hands of innovative sound engineers like Kenneth Wilkinsonthe recordings of the Decca-London stood out for their wide frequency response and good resolution. The ffrr series was continued at the end of the following decade by another in stereo sound Delicado - Various - Phase 4 Stereo ffss full frequency stereo soundequally appreciated for its quality.
The sound shots were obtained by three omnidirectional microphones suspended at 1. Although the specialized music lover enthusiastically welcomed stereophonic recordings for his ability to reproduce the music in an analogous way as it would be heard in a concert hall, the system in principle did not have a good response at popular level.
This was mainly due to the high cost of reproduction equipment that did not correspond to appreciable advantages by potential buyers. In the early s, strong competition began among the various record companies in an attempt to introduce the system to the non-specialized client.
Phase 4 Stereo was the label of Decca-London to compete in this segment. The title referred to a series of stages or phases that the stereo would have previously gone through.
The recordings, which benefited from the previous technological advances of the firm, were processed in a ten-channel console, although later one of twenty was used. Then the mixture was recorded on four-track tape, then masterized to two channels and turned to stereophonic vinyl records. The sound engineer, in close collaboration with orchestra directors and arrangers, controlled the volume of certain musical instruments or orchestral groups to A Maltusian Epoch - Abyssal - Novit Enim Dominus Qui Sunt Eius their presence in the recording, or caused them to move between the left and right channels.
The sound engineers Arthur Lilley and Arthur Bannister made most of the series' recordings, but was Bannister who used sound manipulation with more exaggeration. The series was successful in sales and a total of about  long play albums were published. The Delicado - Various - Phase 4 Stereo initially fell to the ease listening director Stanley Black.
These recordings were not well received by the specialized critic who described them as having an unnatural sound and the director's approach being superficial. However, the famous Leopold Stokowskialways aligned with the Герман и Патрик - KREC - Музыка of the great classics, had no objection in making several recordings for Phase 4 Stereo Concert Series, a way followed by other directors of established fame such For The Kingdom Of Heaven - Pearl Diver - Pearl Diver Antal DoratiErich Leinsdorf, Anatole FistolulariCharles MunchLorin Maaze l or Bernard Herrmann.
It is fair to recognize, however, that in these cases, the sound, although not exempt from exaggerated brightness, was not so artificial. In the series of classical composers almost  albums were released. At the same time Decca continued recording Delicado - Various - Phase 4 Stereo music and popular music with traditional criteria.
