San Antonio—(June 25, 2013)—Musicians and Internet2's K20 Initiative will demonstrate today technology that enables real-time, simultaneous, live musical performances over the Internet. The performance will occur during the International Society for Technology in Education (ISTE) Annual Conference and Exposition, held at the San Antonio Convention Center.

The musicians, separated by more than 1,300 miles from Los Angeles to San Antonio, will perform together over Internet2's ultrafast, 100 Gigabit-per-second computer network and showcase advancements in the latest low-latency audio and video technology, called LOLA.

The musicians, Daniel Hutchins and Jacob Mann, will perform a jazz version of the 1955 hit "You Don't Know Me." Hutchins, who teaches at Friona High School in Texas, will sing live in San Antonio, and Mann, a jazz and pop piano student at the University of Southern California (USC), will play the piano.

The LOLA technology reduces the latency to effectively 35 milliseconds. This musically translates to 35 feet, equivalent to being on the opposite side of the stage. High-speed data transfers and low latency are critical for simultaneous, live, video and audio performances. The technology is groundbreaking by providing lower latency than any interactive audio-video developed for this application so far, according to Dan Nichols, NIU School of Music multimedia specialist.

The Conservatorio G. Tartini in Trieste, Italy, and the GARR Italian Research & Education Network, developed LOLA, which is being used by an increasing number of universities, according to Claudio Allocchio, senior technical officer of GARR.

Musicians are able to effectively play simultaneously and remotely with latency under 60 milliseconds round trip from microphone to musician. LOLA via an advanced network provides a round-trip microphone to speaker latency between 20-50 milliseconds, depending on distance and network configuration. Most commercial services produce a round-trip latency greater than 200 milliseconds. Latency in digital audio equipment is most noticeable when a singer's voice is transmitted through their microphone, digital audio mixing, processing and routing paths.

"Since Internet2's inception, all across the world I have been asked by musicians, 'Can we play together?' and the answer has always been no," said Ann Doyle, director of cultural collaborations, Internet2. "It is with gratitude to the LOLA project team, that now the answer is yes!"

The performance was made possible by staff and technology provided by AT&T, CENIC--the Corporation for Education Network Initiatives in California, Lonestar Education Research and Education Network, Northern Illinois University School of Music, Texas A&M University, and the USC Thornton School of Music.
