Amadeus Acoustics Introduces Downmix Engine Feature

	"The Downmix Engine ensures that whether you are a director checking cues in a stereo rehearsal room, a mix engineer in a mobile broadcast truck, or a performer waiting backstage, the integrity of the acoustic space is perfectly preserved."

Amadeus Acoustics has released ART::Director v1.3.1. The major software update introduces a Downmix Engine feature, which, the company says, resolves one of the performing arts industry's greatest challenges: translating complex, immersive venue mixes into standardised formats for broadcasting, studio pre-production, and ancillary monitoring.

While spatial audio has redefined the audience experience inside major auditoriums, venues frequently face the logistical headache of exporting those multi-channel mixes to external environments that lack massive loudspeaker arrays. The new Downmix feature acts as a direct bridge, allowing sound engineers to run multiple, highly customisable speaker-based downmixes in parallel following the primary in-house spatial mix.

In an event on the scale of the Eurovision Song Contest, where Amadeus Acoustics served as an official technical supplier for 2026, the main audio mix in the arena must simultaneously serve several parallel destinations: To the broadcast van, engineers can deliver a dedicated spatialised 5.1 or stereo fold-down directly to the mobile broadcast truck for pre-production, allowing most of the house mix to be prepared before or in between the very limited number of stage rehearsals. To rehearsal and green rooms, simultaneously independent downmix feeds can be sent backstage so that production crews, artists, and the wider team can perfectly track their positioning and cues in the show's timeline, knowing exactly where they are in the show at any given moment.

"Immersive audio shouldn't be trapped inside the auditorium," says Volker Werner, of Amadeus. "The Downmix Engine ensures that whether you are a director checking cues in a stereo rehearsal room, a mix engineer in a mobile broadcast truck, or a performer waiting backstage, the integrity of the acoustic space is perfectly preserved."

The update also radically transforms the pre-production timeline for sound designers working on world-class performing arts spaces. For example, at an opera house like Theater an der Wien, which features an Amadeus Immersive Sound and Active Acoustics installation, the Downmix Engine feature unlocks a new workflow between the studio and the main stage.

Instead of tying up the main auditorium for days, sound designers can use the Downmix Engine feature to build and tweak complex spatial soundscapes entirely within a separate, offline studio space using smaller, standard monitoring setups (5.1, stereo, or even headphones!). By placing the Downmix Systems as physical, interactive globes within the 3D software venue map, creative teams can accurately simulate how sound movements will scale. When the production finally moves to the main stage, the groundwork is already laid, drastically cutting down on-stage technical rehearsal time.

The Downmix Engine feature supports standard formats like Stereo, 5.1, 7.1, and Atmos, alongside custom loudspeaker configurations. Every parallel downmix system features an integrated size multiplier to widen or narrow the field based on the target room's loudspeaker resolution, individual fade controls for spatial and performing sources, and an independent, dedicated LFE (Low-Frequency Effects) output. Performer sources can be exclusively mapped to the main frontal loudspeakers of the studio setup, ensuring isolation from the surround and overhead loudspeaker channels.

Other features include the introduction of pattern-based OSC addresses alongside variables and properties in OSC addressing. This also ensures full compatibility with ADM-OSC. Scaling can be applied either to the overall boundaries or configured individually for each OSC source. Also: additional performer source gain offsets designed explicitly for fill, precedence, and subwoofer systems, plus support for negative loudspeaker delay offsets; significantly improved Director/DSP connection handling, automatic network port detection, and a built-in connection history log for rock-solid stability during live operations; and adjustable crossfades between venue snapshots, customisable value mapping, and granular fade-out gains within immersive fade zones.
