Waldour Street Mastering

Located in Maryland, Wardour Street Mastering derives its name from Wardour Street, perhaps the central hub of London's Soho district and a hotspot for rock's mid to late '60s "mod" movement. Specifically, Wardour Street remains the location of legendary live club venues like the Marquee Club, where such prominent British acts as The Yard Birds and The Who played during the second half of the 1960s.

In 2005, Wardour Street Mastering was selected to restore and master the historic Diamond Disc recordings, by Thomas Edison. Though the process was time-consuming - requiring significant attention to detail - chief engineer Michael Williams found an indispensable tool for the job in the PreSonus Eureka.

He said, "Recently, we used a pair of PreSonus Eurekas in the restoration and mastering of the original Thomas Edison Diamond Disc recordings. Throughout this process, your product proved indispensable. More than eighty-five years of poor storage, along with the inherent imperfections of very early recording technology, practices and mediums made this project a challenging one.

Once the massive amount of noise was removed from these recordings, we noticed that the dynamic range was significantly offset by the fact that, during the recording of these discs, a single cone-shaped device was used to capture the sound. The vocalist was directly in front, while the band was positioned some five to ten feet away on bleachers. Consequently, one can barely hear the music, while the vocals are sharp and piercing. This would be unacceptable for commercial release. We needed a transparent, unobtrusive compressor with very quiet amplifiers. We found this in the Eureka. The compression was pleasantly musical and without unwanted artifacts that would otherwise compromise the integrity of the recordings. We just wanted to let you know that the Eurekas played a huge role in preserving some of the earliest examples of commercially produced, recorded sound."
