Why it mattered

  1. 01

    Reframed the concert mix as positioned sound objects reproduced by multiple arrays.

  2. 02

    Used a wide frontal scene to improve correspondence between visible performers and perceived source location.

Engineering record

Frontal system
L-ISA uses amplitude-based rendering across at least five frontal arrays in a Hyperreal configuration.[1]
Object capacity
Documented systems can position up to 96 sound objects in three-dimensional space.[2]

Original pricing

No public launch price located

2026 equivalent

Not calculated without a reliable original price.

L-ISA is configured and quoted as software, processing, and loudspeaker infrastructure for each production.

Use in the field

Documented uses include Johnny Marr, Mark Knopfler's 2019 tour, and Hans Zimmer Live in Las Vegas.[2][3]

Professional reactions

“The separation is unbelievable, without it feeling like it's separate sources.”

Later field experience · 2020

Whitesel and system technician Andrew Gilchrest found the mix image and tonality natural and consistent across each arena, including distant and side seats. He valued immersion that strengthened engagement with the music rather than distracting audiences with effects.
