Surviving Audio vs BrownBox

Plan the show, before the show. Surviving Audio is the pre-show planning suite for working sound engineers. Built around real-world workflows from the live PA design playbook — McCarthy-grade math, dynamically visualized, with practical guides on every tool. The big six: Stereo PA Quick-Eval — Type room dimensions (W × D), get a complete system recommendation: speaker spacing, coverage range, throw distance, FAR/LAR, plus a class verdict (long-throw, standard, wide, multi-box). Answers "which system do I bring?" in 30 seconds. Multi-Tower Delay Chain — One tower? Five towers? The app calculates the position and electrical delay for every tower based on your venue depth and the 40 ms threshold (temperature-adjusted). Visualizes the entire chain with side-elevation diagram. Spatial Crossover — The exact position where main and delay tower meet at equal level, plus the delay setting in ms and samples. Includes a level-vs-position SPL plot showing the transition zone. Sub Setup Recommende — Number of subs + crossover frequency + stage width = the right configuration. Single, coupled, stereo (with power-alley warning), cardioid stack, end-fire, distributed, or coupled block. Each rendered as a top-down stage diagram with λ/2 reference. Cardioid + End-Fire Sub Designer — Calculate delays, polarity, and forward gain. Interactive polar plots at chosen frequency. Top-down layouts with dimensioned spacing. Line Array Splay (Field Estimate) — Rough estimation of splay angles using only a laser distance meter. Side-elevation showing progressively splayed boxes. Pre-MAPP/ArrayCalc reality check. And much more:

BrownBox reads an L-Acoustics Soundvision System Report and hands you every hang the way you rig it: box counts, per-box splay, top and bottom trim, weight with the flying frame, bumper count, pickup hole and site angle. Open the PDF on your phone, walk to the point, and the numbers are in your hand. Built by a touring audio tech, for the people who fly the PA. EVERY HANG AT A GLANCE • Import any Soundvision System Report (PDF) — straight from Files, Mail or AirDrop • Mains, subs, fills and delays laid out like the console, each with box count and cabinet models • Per-box splay angles and a side-profile view of the array • Top trim and bottom trim, in feet or metres RIGGING, NOT JUST ACOUSTICS • Weight per array, including the flying frame, in lb or kg • Bumper count, pickup hole and front/rear pins from the report • Site angle starred on a two-motor hang, pickup hole starred on a one-motor hang, so the number that actually sets the tilt is the one you see first • Verified cabinet weights for K1, K2, K3, KARA II, KIVA II, A15, A10, KS28, KS21, SB18, SB15m, L2, L2D, SYVA, SYVA LOW, X8, X12, X15 — anything estimated is marked ≈ THE RIGGER LIED (Pro) • Riggers report the as-built trim or site angle from their own phones with a short show code • The lead sees every hang that's off from the design, live, as it's flown ON SITE • Track each hang from Pending to Deployed to Noised, with a Noised tab for system check • Share a rig card — trim, weight, splays, holes — as an image straight into the show chat • Works offline. No account. Your designs never leave your phone unless you share them. FREE AND PRO Importing reports, box counts, splays, the side profile and the status tabs are free. BrownBox Pro ($24.99/year) unlocks weight, top and bottom trim, full rigging detail, the rig card and the live Rigger Lied sync.
