Facilities like the Columbia Records 30th Street Studio in New York and Abbey Road Studios in London were renowned for their 'trademark' sound—which was (and still is) easily identifiable by audio professionals—and for the skill of their staff engineers. As the need to transfer audio material between different studios grew, there was an increasing demand for standardization in studio design across the recording industry, and Westlake Recording Studios in West Hollywood was highly influential in the 1970s in the development of standardized acoustic design.
