Spatial audio in Lithuania – loudspeaker installations and concerts 2013–2026

Thu, 01 Oct 2026 15:00:00 +0200

Since I came to Vilnius as an ERASMUS student in 2012, I have set up loudspeaker domes and spatial audio systems in all kinds of places in Lithuania – from a historic observatory to the National Philharmonic Hall. A look back, from my talk at Raum und Klang 2026.

2013 – a sphere for the music academy

During my ERASMUS year at the Lithuanian Academy of Music and Theatre (LMTA), the plan for the new Music Innovation Studies Centre was already there: EU funding for a spatial audio and recording room – the sphere – plus a mixing room, a lecture room and a co-working space. Building it took some time.

Raum und Klang 2026 – Zimmt Leipzig

Sun, 27 Sep 2026 08:40:00 +0200

I was happy to finally visit Zimmt in Leipzig and present the recent additions to mcfx and ambiX, as well as perform my piece “Spatial Echos from NYC” for clarinet and electric bass!

mcfx_send and mcfx_receive – multichannel audio over the network

Tue, 01 Sep 2026 16:00:00 +0200

Two new plug-ins in the mcfx suite: mcfx_send and mcfx_receive stream lossless multichannel audio over a wired network – from one computer to another, or from one DAW to another on the same machine. Both also come as standalone apps, so no DAW is needed. Low latency, automatic discovery, optional password protection.

The goal: set up in seconds, no frills, it just works.

mcfx_send

mcfx_receive

Why

They were made for spatial audio jam sessions and concerts, where several people bring their laptops and everything has to end up on one loudspeaker system. Proprietary audio-over-network solutions caused a fair share of problems there: license trouble even after buying one, drivers that stop working after an OS update, endpoints that aren’t discovered. They are built for hardware units, not for laptops. JackTrip needs JACK; SonoBus does much more than needed and costs a lot of CPU.

reaper_ambix – read/write .ambix files - lossless and lossy Ambisonic compression, loudness normalization, ...

Tue, 01 Sep 2026 12:00:00 +0200

reaper_ambix is a free extension for the REAPER DAW that reads and writes .ambix files – the Ambisonics exchange format (C. Nachbar, F. Zotter, E. Deleflie, A. Sontacchi, ambiX – A Suggested Ambisonics Format, Ambisonics Symposium, Lexington, 2011) that goes with the ambiX plug-ins – and adds a few tools for working with Ambisonic sessions. I started it in 2014 and recently gave it a major update.

.ambix as render format and media type

Files can be written as uncompressed CAF, lossless WavPack, or lossy WavPack in hybrid mode at 6, 4 or 3 bits per sample. The noise floor of the lossy mode follows each channel’s level, so the quiet higher-order channels stay quiet and the result survives decoding and rotation.

Dome loudspeaker layout generator – plan an Ambisonic dome in the browser

Sat, 01 Aug 2026 13:00:00 +0200

How many loudspeakers on which rings, at what elevation – and where do they actually go on the truss or the walls of the room? The Dome Loudspeaker Layout Generator is a free web app that answers these questions when setting up an Ambisonic loudspeaker dome, and exports the result straight into the IEM AllRADecoder. It runs entirely in your browser; if it doesn’t load there, use the fallback on Streamlit Cloud.

Orbital Echos From New York – live in the Ambisonic dome

Tue, 15 Apr 2025 10:00:00 +0200

Orbital Echos From New York – for electric bass, clarinet and spatial electronics – performed at the Live Spaces workshop in Vilnius on 10 April 2025, at Vilniaus plokštelių studija, inside the Dirty Deal Audio Ambisonic dome.

Thanks to Palle Dahlstedt and Kristaps Puķītis for the video recordings, and Tomas Terekas for the photos.

Live electronics for Salonen's Cello Concerto – Nicolas Altstaedt and LNSO in Vilnius

Tue, 29 Oct 2024 19:00:00 +0100

On 29 October 2024 I performed live electronics for the Lithuanian premiere of Esa-Pekka Salonen’s Cello Concerto, with Nicolas Altstaedt as soloist and the Lithuanian National Symphony Orchestra (LNSO) conducted by Modestas Pitrėnas, at the Lithuanian National Philharmonic in Vilnius, as part of the Gaida festival.

In the concerto, the electronics sample the solo cello live and turn it into echoes and textures – the cellist’s own lines return, layered, around the orchestra.

Sound installation for the light tunnel at Swarovski Kristallwelten

Fri, 01 May 2015 12:00:00 +0200

For the 2015 expansion of Swarovski Kristallwelten (Swarovski Crystal Worlds) in Wattens, Tyrol, I created the interactive sound installation for the light tunnel – the retail corridor that leads visitors into the new shop.

Photo: Patrick Lüth

The tunnel

The corridor is a shortcut: it takes visitors directly to the shop inside the Giant, without the walk through the Chambers of Wonder. Even so, the few metres should feel like part of the Crystal Worlds rather than a plain hallway.

Headtracking for Binaural Ambisonic Playback

Fri, 02 May 2014 07:04:17 +0200

Here is a short tutorial about an inexpensive headtracking solution which you can use to improve the binaural listening experience with the ambix Ambisonic tools. The calibration software is currently Windows only, but the Pd patch is naturally cross-platform.

It uses the headtracker described here by Dennis Frie: http://www.rcgroups.com/forums/showthread.php?t=1677559
Parts: arduino nano, GY-85 sensor board.

A Pure Data patch provided by me receives the serial data from the Arduino based headtracker and sends OSC messages to the host of your choice. In this case I will describe the use within the digital audio workstation Reaper.

ambiX – Ambisonic plug-in suite

Sat, 25 Jan 2014 18:44:35 +0100

ambiX is a suite of free, cross-platform Ambisonic plug-ins for producing and post-producing 3D audio – encoding, rotating, warping, widening, decoding to loudspeakers or to headphones. They work in any multichannel host such as REAPER, Ardour or Max, and as standalone applications.

I first released them in January 2014, developed during my master thesis at the Institute of Electronic Music and Acoustics in Graz. Together with mcfx they won the gold award at the AES Student Design Competition 2014, were promoted by Google for YouTube Ambisonics productions, and are still in wide use. The plug-ins follow the ambiX convention: full 3D, ACN channel order, SN3D normalization.

Download: github.com/kronihias/ambix/releases – installers for macOS and Windows; on Linux they can be built from source. Source code: github.com/kronihias/ambix (GPL).

mcfx – multichannel audio plug-in suite

Fri, 10 Jan 2014 17:54:04 +0100

mcfx is a suite of free multichannel plug-ins for macOS, Windows and Linux: convolution, EQ, filters, delay, gain calibration, metering, network audio and more – each one processing any number of channels in one go. That makes them handy wherever many channels belong together: loudspeaker arrays, Ambisonics (together with ambiX), microphone array recordings.

I first released mcfx in January 2014, alongside ambiX; in 2026 it got its largest update so far. As VST3, every plug-in adapts to the channel count of the track (up to 64); the installers also include fixed 128-channel VST2 versions for hosts that need more.

table top – binaural recording

Thu, 28 Nov 2013 08:16:29 +0100

table top is a live performance by Matthias Kronlachner created for the loudspeaker sphere in the Astronomical Observatory tower of Vilnius University.
The performance was recorded on November 22nd, 2013 and December 3rd, 2013.

The original format of the piece is 5th order 3D Ambisonics, but you can listen to a binaural mixdown here: (please listen with high quality headphones!)

table-top-4 (November 22nd, 2013)

table-top-6 (December 3rd, 2013)

The binaural mixdown was done with the ambix Ambisonics Plug-Ins and the 24 binaural loudspeaker impulse responses are taken from the IEM Cube. Therefore you are virtually placed in the IEM Cube during listening to this piece with headphones.

Chalva (4 channel tape)

Mon, 08 Apr 2013 14:02:19 +0200

Is it natural, is it artificial? What is “real”, what is synthetic?
This questions apply for sound as well as sweets.

This piece is based on field recordings taken near Fethiye, in the south of Turkey. From the numerous bee yards a whirling sound surrounds you when tracking the Lycian way along the cost.
Chalva is a sweet made with honey. But depending on the recipe, the natural origin might not be clear.

Homage to Luciano Berio (1925–2003)

Mon, 08 Apr 2013 12:17:01 +0200

midi2rms – midi volume fader curve sampling

Fri, 21 Dec 2012 19:18:01 +0100

A very crucial and maybe often underestimated point for working with (volume) faders, especially in live electronics application is their curve/behavior. Which range does it cover? How fast does “it” get “loud”. What is the behavior around the +0 dB mark?

I sampled the midi volume fader behavior from several of the most popular Digital Audio Workstations. The difference is quite obvious as you can see in the graph to the right.

non-standard scale/tuning playback via midi

Tue, 21 Feb 2012 13:09:14 +0100

In my composition studies at “lietuvos muzikos ir teatro akademija” in Vilnius I came across using 12 tone techniques from Schoenberg/Hauer in combination with the Bohlen-Pierce¹ scale discovered independently by Heinz Bohlen in early 1970’s and John Pierce.

This scale is based on mainly odd frequency ratios and divides the duodezime (ratio 3:1) into 13 steps. You can listen to the equally tempered scale here:

Rondo – Eine schwingende Platte

Tue, 28 Jun 2011 00:02:48 +0200

Aufbau Installation

Künstler verschiedener Genres haben verschiedene Anforderungen an den Arbeitsraum. Wenn man mit Klang arbeitet ist unter anderem eine gute akustische Trennung zur Außenwelt eine wichtige Voraussetzung.

Das Rondo kann in dieser Hinsicht nicht als optimal gelten und diese interaktive Klanginstallation macht die Schallübertragung über den Estrichboden im Rondo hörbar.

Schallwandler (Piezo-Pickups) sind über den 4. Stock am Boden verteilt und liefern je nach Schuhwerk des daran vorbei spazierenden Besuchers Signale mit unterschiedlichem Charakter.

Screenshot

Am Terminal, wo alle Signale zusammenlaufen, kann man sich gesteuert von einem WII-Controller in Echtzeit mittels Kopfhörer in dem virtuellen Rondo-Klangraum bewegen und in die in Schwingung versetzten Strukturen hineinhören.

Folgendes Video ist für Kopfhörerwiedergabe optimiert. Die Klangbeispiele sind nur illustrativ und entsprechen nicht denen der realen Installation.
