noch etwas zu Dolby, der "Dolby A Trick":
"Double Fantasy was recorded with
no Dolby noise reduction so these 361's would not have been in use for that purpose. There is another possibility though. A technique that became very popular in the seventies - now usually referred to as the "Dolby A Trick" - involved using Dolby A as an enhancer. Encoding Dolby uses a series of filters and upward expansion, so recording a signal through the encode side but playing it back without decoding added subtle high frequency sheen and luster to a signal dynamically.
Engineers found that this effect could be further refined by modifying their units. The encoding process works by splitting the signal into four different frequency bands, and by disabling the encoding on the bottom two (under 3kHz) bands the effect was enhanced even further."
