EU project REPERTORIUM unveils new AI-based interactive spatial audio at Lithuanian National Philharmonic concert

The Lithuanian National Philharmonic Society, a partner in the EU-funded REPERTORIUM project, will host a landmark event marking the culmination of a three-year, €3 million European research initiative that is redefining how audiences experience classical music.

By December 2025, Stefan Lano's Piano Concerto No. 2 will be available on this interactive streaming platform. Visitors will be able to explore the orchestra virtually, listening from different positions (next to the clarinets, behind the timpani, or in the conductor's place) and discover how technology is transforming the perception of live performance.

A Landmark Musical Event

As part of the closing concert of the 9th Vilnius Piano Festival on 29 November 2025, the Lithuanian National Symphony Orchestra will present the world premiere of Swiss conductor and composer Stefan Lano's Piano Concerto No. 2, dedicated to the renowned pianist Mūza Rubackytė, conducted by the composer.

This concert also serves as the final field test of REPERTORIUM's innovative AI-driven interactive and immersive audio formats, developed collaboratively by Politecnico di Milano, University of Jaén, University of Alicante, University of Tampere, and Odratek.

Revolutionary AI Technology

Using only a few strategically placed microphones combined with advanced artificial-intelligence signal processing, the system reconstructs a three-dimensional sound field that allows listeners to move virtually within the orchestra, focus on individual instruments, remix or even mute a section.

Source Separation

Utilizes machine learning to cleanly extract the signal of each instrument group and separate them into individual stems, a feat previously impossible for the symphony orchestra.

Sound Field Reconstruction

Utilizes artificial intelligence to recreate how the music sounds from any position in the concert hall by analyzing signals captured by advanced microphones placed around the space.

Six Degrees of Freedom (6DoF)

Creates a lifelike, three-dimensional "acoustic hologram" of the hall, where listeners can move freely within the sound. This brings 6DoF immersive and "Music Minus One" functionality to classical music for the first time.

The Lithuanian National Philharmonic Society, a leader in concert recordings and digital broadcasts in the region (the organization was one of the first to open its own digital concert hall), representing musicians of the highest standard of mastery, congratulates the Repertorium project and its creators, scientists, and specialists on the project's achievements. This is a major technological achievement and a unique development in the classical music listening experience.

This concert marks a turning point in how online audiences can experience orchestral music. By combining AI with spatial audio engineering, we can now recreate the acoustic perspective of any listener inside the concert hall. Beyond the artistic impact, this innovation opens new possibilities for future concert recordings across Europe.
