Actually more than mentioned, we met an unbelievable man who was involved with the invention of this fascinating technology.  His name is Frank Laico, and he is a CBS Recording Engineer Emeritus who’s recording credits reads like a who’s who in hit records. (Sinatra, Bennett, Streisand, and on and on and on). Frank was the guest speaker at the recent AES Meeting in Seattle. Magnificant gentleman who gave us three hours of fascinating information regarding making hit records back in the days when hit records were really records.

Back to SIGSALY. The brief description (from Wikipedia)

n cryptography, SIGSALY (also known as the X System, Project X, Ciphony I, and the Green Hornet) was a secure speech system used in World War II for the highest-level Allied communications. It pioneered a number of digital communications concepts, including the first transmission of speech using pulse-code modulation.

Frank Laico and his military buddies were pioneering digital audio long before digital …existed.

So go put on a Miles Davis album, (also recorded by Frank) , sit back and read all about SIGSALY  here. Fascinating story.

While you are at it, Google Frank Laico. His story and recording credits are amazing as well.
