On November 29, 2025,theLithuanian National Philharmonic Society – partner in the EU-funded REPERTORIUM project – will host a landmark concert culminating a three-year, €3 million European initiative redefining the way audiences experience classical music.
“This concert marks a turning point in how online audiences can experience orchestral music. Combining AI with spatial audio, we can recreate the acoustic perspective of any listener in the hall—and open new possibilities for future recordings across Europe.”
Julio J. Carabias-Orti, REPERTORIUM technical coordinator (University of Jaén)
World Premiere & Final Technology Test
As part of the 9th Vilnius Piano Festival’s closing concert, the Lithuanian National Symphony Orchestra will present the world premiere of Stefan Lano’s Piano Concerto No. 2, dedicated to pianist Mūza Rubackytė and conducted by Lano himself. This concert will also serve as the final field test for REPERTORIUM’s innovative AI audio formats, created collaboratively by Politecnico di Milano, University of Jaén, University of Alicante, University of Tampere, and Odratek.
Interactive Streaming Platform Launch
By December 2025, this concert will be available on REPERTORIUM’s interactive streaming platform, where users will virtually explore the orchestra, listening from different positions—beside the clarinets, behind the timpani, or at the conductor’s podium—and uncover how technology transforms live performance perception.
From AI to Acoustic Magic
Using only a few strategically placed microphones and advanced AI signal processing, REPERTORIUM reconstructs a three-dimensional sound field. Listeners can move virtually within the orchestra, focus on specific instruments, remix, or mute entire sections. This is the first time “Six Degrees of Freedom” (6DoF) and “Music Minus One” features are available for classical music.
Source Separation and Sound Field Reconstruction
Source Separation uses machine learning to cleanly extract and separate each instrument group’s signal into individual stems—a feat previously impossible for symphony orchestras. Sound Field Reconstruction re-creates how the music sounds from any seat in the concert hall, generating a lifelike three-dimensional “acoustic hologram” in which listeners move freely: this is 6DoF audio.
REPERTORIUM not only celebrates Lithuania’s leading orchestra but demonstrates how European research and innovation open new possibilities for classical music recording and accessibility. The technology has been successfully tested with the London Philharmonia, Brandenburg State Orchestra Frankfurt (Oder), and culminates in Vilnius.
“The Lithuanian National Philharmonic Society, a pioneer in concert recordings and digital broadcasts in the region, is honored to represent musicians of the highest mastery and congratulates the REPERTORIUM project and its team for this unique achievement.”
Ieva Tamutytė, Deputy Director of the Lithuanian National Philharmonic Society
