SoundMess Lab vs DFTM Audio Tools

SoundMess Lab is a careful, offline sound measurement tool for iPhone and iPad. Built for musicians, producers, podcasters, acoustic enthusiasts, and anyone who wants to understand what they're hearing. WHAT IT MEASURES • SPL meter — A/C/Z weighting, Fast/Slow/Impulse time weighting, Leq, L10, L90, Lmax, Lmin, Lpeak, with one-tap session reset • Real-time analyser — 1/1 to 1/24 octave bands with peak hold • FFT — Hann, Hamming, Blackman, Blackman-Harris windows, sizes up to 65,536, exponential averaging • Spectrogram — five tuned colour palettes, live and rolling (Pro) • RT60 — per-octave-band reverberation time, ISO 3382-2 T20 method with interrupted pink noise (Pro) • Signal generator — sine, pink, white, swept sine (Pro) • Reference-tone calibration — trim every reading against a known 94 dB source (Pro) BUILT CAREFULLY SoundMess Lab implements the IEC 61672 A/C/Z weighting curves with published coefficients to 10 decimals, Paul Kellett pink noise, and ISO 3382-2 T20 linear regression for RT60 fitting. Every reading shows a confidence indicator so you know which frequencies you can trust — built-in iPhone microphones have known hardware limits below 500 Hz and above 8 kHz, and we don't pretend otherwise. HONEST ABOUT LIMITS Every phone microphone has physical constraints. SoundMess Lab shows you where it can be trusted and where it can't. It's a serious listening tool for creative work — not a replacement for a calibrated measurement microphone in professional field acoustics or compliance settings. PRIVACY BY DESIGN Nothing you measure ever leaves your device. No account, no analytics, no ads, no cloud. Audio is only written to disk when you start a recording, and those files stay in your app sandbox until you choose to share them. FREE INCLUDES SPL meter (with L10 / L90 / session reset), 1/3-octave RTA, FFT (4096 · Hann), per-device microphone compensation, five themes. PRO UNLOCKS Spectrogram (live + rolling), RT60 room-acoustics measurement, fractional RTA (1/6, 1/12, 1/24), advanced FFT (sizes up to 65,536, Hamming / Blackman / Blackman-Harris windows, exponential averaging), signal generator (sine / pink / white / sweep), recording & playback, WAV / CSV / PDF export, reference-tone calibration, external mic calibration-curve import (.txt / .frd). PRICING • $8.99 one-time Lifetime · Family Sharing supported One-time purchase. No subscription, no auto-renew. BUILT FOR THE WORK Most sound apps optimise for the spike — big colourful needles and "how loud is a rock concert" trivia. SoundMess Lab is built for the work: reading a room, shaping a mix, checking a speaker, measuring a decay, teaching acoustics. Careful DSP, calm UI, no noise.

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.
