TiMax helps put space into National Gallery’s Soundscapes
‘Soundscapes’ at the National Gallery, London – exhibiting through July until September 6th 2015 – showcases the sonic interpretation by contemporary sound artists, composers and musicians of six individual artworks of their choice from within the National Gallery.
Jon Sheldon, the National Gallery’s Senior AV Engineer, specified TiMax SoundHub matrix server systems to provide playback, scheduling, signal distribution, dsp and spatialisation across the multiple zones of distributed Bowes & Wilkins loudspeakers. Out Board’s Dave Haydon provided TiMax design, programming and commissioning support prior to the installation and also on-site, including spatial mix sessions with musician/producer Jamie xx and composer Nico Muhly’s sound designer Jethro Cooke.
These two exhibits fully exploited the object-based TiMax 3D audio capabilities to help render their sonic interpretation of the artists’ chosen artworks. Nico Muhly used 20 stems mixed to 8-channels of surround plus sub, featuring 24 highly immersive floating violas da gamba and slowly panning dulcitone and crotales percussive motifs, blended with occasional enveloping electronic keyboard and bass-synth elements punctuated by concert bass drum.
The 38-track composition created by Jamie xx had its own TiMax SoundHub-S48 for playback, scheduling and 3D audio spatialisation across 16 B&W speaker channels plus two subs. The Jamie xx system incorporated a surround zone to deliver a full immersive mix at the back of the room followed by lines of ‘layered’ speakers which gradually fragmented the music spatially as the viewer approached the Pointillist painting at the front of the room. TiMax was programmed to immersively spread and move individual samples and beds within this very unique multi-dimensional panorama.
A main TiMax SoundHub-S64 provided playback, scheduling, EQ and signal distribution, as well as zone level control via iPad interface, for the Nico Muhly room plus three others: Chris Watson’s (BBC/Channel4) four-channel lakeside nature recordings, film composer Gabriel Yared’s (English Patient) 13-track ensemble and soprano piece, (mixed in the space by sound designer Alain Francais using the TiMax Dante64 interface hooked up to Nuendo), and Turner Prize Winner Susan Philipsz’ three channels of mysterious discordant violin. A further TiMax SoundHub-S64 unit was in place for redundant backup, containing copies of all shows and content, able to switch over at a moment’s notice.
The iPad control, based on a fully customisable MiniServer web-based interface developed by Out Board associates 1602 Group, proved invaluable during setup and press events. One interesting aspect of the Soundscapes set-up required the National Gallery’s Jon Sheldon and its Conservation Department to restrict sound pressure and vibration at the artworks’ surfaces to a safe level, to ensure that fragile paintings would not be put at risk. Levels were fine-tuned via zone control Groups on the iPad while SPL and vibration measurements were made, then final levels were transferred to TiMax SoundHub output faders and stored in the System Preset. TiMax output EQ was also used to filter out specific potentially troublesome sub-bass frequencies.
Prior to opening AV engineers Alessandro Sorenti and Andrew Balham accompanied each artist round their space to fine tune the level to their taste, and during press night the iPad was used to dim individual rooms’ local playback level during recording of interviews by TV and radio crews including the BBC. It also proved helpful when the whole exhibition needed to be faded down for one minute’s silence to mark the anniversary of the 7/7 bombings and also in honour of the Tunisia terrorism victims.
Soundscapes was considered a bold and progressive departure from the National Gallery’s usual summer exhibition programming, and triggered a broad spectrum of acclaim and controversy in the art world.
Out Board’s Dave Haydon commented, "We're happy to be involved with experimental projects that are sometimes regarded as crossing boundaries, a lot of things we do with TiMax are bleeding edge and pushing the envelope. I think it’s to the National Gallery's credit to do something outside their normal comfort zone.
