Leadsheet vs Surviving Audio

Power your live performances with a simple and reliable sheet music and setlist organizer! SETLISTS Create setlists for all your different shows and bands. Intuitively drag and drop files from your archive to your setlists or open your favourite cloud storage within the app and import sheet music directly into your setlists. SHEET MUSIC LIBRARY Download all your sheet music from iCloud, Dropbox or Google Drive. Of course scores can also be received via Airdrop because there is also the one band member that forgot to download the new song you practiced at rehearsal. ANNOTATIONS Leadsheet allows you to annotate your sheet music in all kinds of different ways so you never miss that Coda again! BACKUP AND RESTORE Switched to a new iPad? Simple backup all your Leadsheet data and restore it on another device, all your annotations and setlists are transferred to the new device exactly how you left off.

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.
