About the Event

Glenn Gould‘s extraordinary career was book-ended by recordings of J.S. Bach’s Goldberg Variations. The release of his 1955 mono, analogue debut recording on Columbia Records placed him immediately among classical music’s superstars. His 1981 stereo, digital recording was released just a few weeks before his death.

At the turn of the 21st century, Zenph® Sound Innovations, Inc developed software which analyzes a recorded piano performance and stores it as high definition MIDI data for playback on a robotic piano such as a Yamaha Disklavier Pro concert grand. Toronto AES member Jim Hayward was the catalyst for bringing the Zenph/Gould project to Toronto. Some Toronto AES Section members will recall a presentation by Zenph at the Japan Center in 2006.

Later that year a “re-performance” of the famous 1955 version of the Goldbergs was recorded in the Glenn Gould Studio at the CBC in Toronto using Zenph’s re-performance technology. From the resulting SACD the listener can choose to enjoy the same performance in either stereo, surround or binaural sound.

Peter Cook was one of the recording engineers on the session. Peter will tell the story of how the recording came about and talk about some of the technology and recording techniques used at the recording session. Jim Hayward will be on hand to deliver additional commentary.

Attendees will also be able to hear the high resolution recordings – which earned a perfect 5/5 for sound and 5/5 for performance from Absolute Sound and was named “Recording of the Month” by Stereophile – played back in stereo, surround and binaural sound.

Parking is available in Lot 1 on campus, or on the street after 6:00 pm.  The meeting is in Building AX, immediately off of Lot 1 (north side).
