Surviving Audio vs DFTM Audio Tools

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:

Dog From The Moon Audio Tools is a professional live audio toolkit built for touring engineers, festival crews, monitor engineers, and system techs who need fast, reliable tools in the field. Whether you are ringing out a PA, prepping IEMs, building a patch sheet, or running a show from the monitor desk, everything lives in one dark, stage-friendly interface designed for real-world use. CRITICAL MEASUREMENT TOOLS • RTA / Spectrum Analyzer — real-time frequency analysis with input level control and peak identification • Feedback Detector — find ringing frequencies fast and hold the most recent hits for quick EQ decisions • Sound Level Meter — calibrated SPL measurement using your iPhone microphone • Polarity Checker — verify speaker and line polarity in the field IEM LAB • IEM Hearing Curve — professional-style per-ear hearing test with automatic progression, pulsed tones, and PDF export • IEM Response Test — measure left and right IEM/headphone response with mic compensation and confidence reporting • Tuner — pitch and cents detection from the microphone • Signal Generator — sine, pink, and white noise for testing and alignment SHOW PRODUCTION • Patch Sheet Builder — create input and output patch sheets with stereo routing, rack numbers, and color grouping • Rig Weight Estimator — plan line array hangs, subs, delays, and outfills with hoist load calculations and PDF export • Monitors — save artist profiles, pack details, wedge notes, and mix priorities • Setlists — build show setlists with timecode, track triggers, mixing notes, drag-and-drop order, and Play Mode for live show calling TIME & SYNC • Timecode — LTC generator and reader with transport controls, manual time entry, cues, and optional audio output • Visual / Audio Sync — flash and click tools for A/V alignment • Tap Tempo — live BPM with delay subdivisions • Tempo Calculator — convert BPM to milliseconds FAST CALCULATORS • Delay — distance to time alignment with temperature compensation • Wavelength — frequency to physical length • dB — voltage, power, and SPL ratio calculations BUILT FOR THE ROAD • Dark pro-audio interface designed for low-light environments • Dashboard command center with quick access to every tool • Local-first data storage — your rigs, patch sheets, setlists, and test results stay on your device • Optional iCloud sync — manually upload or download your data when you want it across devices • English and Spanish language support From FOH to monitors to system tech prep, Dog From The Moon Audio Tools puts the measurements, show data, and production tools you actually use on tour into one app. Note: Microphone-based tools require access to your device microphone. Hearing and IEM response tests are intended for professional monitoring workflows and are not a substitute for clinical medical evaluation.
