Watching the Beatles Anthology
TV shows last Thanksgiving, I was struck by how good recorded sound quality was in the early to mid-1960s and how bad it had become by the era of Let It Be
. Early Beatles recordings may have been primitive in terms of production, but their basic sound quality was excellent, with extended response at the frequency extremes and a natural, clean-sounding midrange. Late Beatles recordings lacked highs and dynamic range, and sounded grainy by comparison. This was partly because, by 1969–70, studios had replaced their simple tubed mixing consoles with the first generation of solid-state desks, and their old tubed two-track Studers and Ampexes with solid-state multitrack recorders. These featured track widths so narrow that only the massive use of Dolby-A noise reduction made it possible to produce recordings that had any dynamic range at all!
