A great deal of incredible stuff occurred up in [Bruce Land]’s lab at Cornell this last semester. three trainees – [Pat], [Ed], as well as [Hanna] put in hours of work to find up with a few algorithms that are able to simulate stereo audio with monophonic sound. It’s sufficient work for three semesters of [Dr. Land]’s ECE 5030 class, as well as while it’s impossible to genuinely appreciate this job with a YouTube video, we’re presuming it’s an incredible piece of work.
The very first part of the team’s job was to gather data about exactly how the human ear hears in 3D space. To do this, they mounted microphones in a team member’s ear, sat them down on a turning stool, as well as played a series of clicks. tons of MATLAB later, the team had an typical of exactly how their team member’s heads heard sound. Basically, they produced an algorithm of exactly how binarual recording works.
To verify their algorithm worked, the team took a piece of music, squashed it down to mono, as well as played it with an MSP430 microcontroller. With a great pair of headphones, they’re able to essentially location the music in a stereo space.
The video below covers the fundamentals of their develop however since of the limitations of [Bruce]’s cam as well as YouTube you won’t be able to experience the team’s online stereo for yourself. You can, however, put on a pair of headphones as well as listen to this, a great example of what can be made with this kind of setup.
