University of Illinois professor expertise in machine


URBANA, Illinois, March 02, 2022 (GLOBE NEWSWIRE) — From the first time he used a synthesizer, Illinois computer science professor Paris Smaragdis knew he wanted to learn how technology could create or change the music.

What followed was a career in academia that focused his research on artificial intelligence on the question: what does it mean to take a stream of sound and break it down into its individual components?

The answers he has found over the years have helped him produce widely published research and over 40 patents. But nothing he’s accomplished has been more “mind-blowing” than the recent work he did with a team of engineers to improve the audio quality of director Peter Jackson’s recent documentary titled “The Beatles: Get Back”.

“I remember growing up as a kid, listening to Beatles tapes as I sat in the garden. I started to understand that the Beatles weren’t just a big deal because of the music. They were light years ahead of the rest because of the music production,” Smaragdis said. “Being in a position where I could not only see how they produced their music, but also deconstruct it and unmix it, was definitely a mind-blowing experience.”

Smaragdis heard about the engineering team working on the documentary, at which point they asked if he could help clean up this treasure trove of old Beatles audio.

The original audio came mostly from a microphone that picked up the sounds of a room full of musicians, producers, friends and collaborators. The documentary wanted to extract speech and music from these sounds to properly portray the development of an iconic piece of music for today’s audience.

“That first phone call started with them asking me if it could even be done. I told them if they had tried it 10 years ago I would say there was no way this But we’ve had several big breakthroughs from those years that I think could make that possible,” Smaragdis said.

The whole process took the team nine months.

“I focused on how we could separate and identify all the sounds we encountered. We could identify Paul (McCartney) speaking here, or the voice of George (Harrison) speaking there,” Smaragdis said.

In the end, the months-long process resulted in a sound worthy of the documentary and the monumental group.
