Group Tracker ⊚ vs SoundEngg

Always know where everyone is with Group Tracker, another in our growing line of exciting and innovative iOS apps. We recognize you have a choice of similar apps out there, but Group Tracker is different because: • it’s easy, easy, easy! • no setup, registration or sharing of information • it’s as flexible and dynamic as you are Just gather your group together, the leader taps the Ⓖ button, and that’s it! After that, everyone can follow on the map where everyone is. While the initial intent was to target tour groups, new uses are being found for Group Tracker all the time: • tour groups – especially port-of-call and other time sensitive outings • school and family outings – nature hikes, museums, sporting events, fairs • business uses – conferences and conventions • assistance with mobility issues, translation, or taking pictures! • outdoor sporting events – keeping track of performance • never lose your way when given “Just follow me!” driving directions Fully customizable: icon, nickname, grouping and messaging settings. You can send messages to other group members, either individually or all at once. Messages support full Unicode and Emoji. There is a “Request Help” feature to get assistance from nearby Group Tracker users. You can switch from Map to Satellite view, with support for panning, rotation and zoom-in or -out. A legend is provided to help you estimate distances (metric or imperial). An In-App upgrade provides wider grouping areas (250 m vs 30 m radius), and longer group durations (12 hrs vs 1½ hrs). Strongly recommended for tour group leaders and other professionals. Disclaimers: • “Group Tracker” as used in various places in this description is intended as a short form for “Group Tracker by Russell Harper” • the continued use of GPS running in the background can dramatically decrease battery life; in our testing, we have found the discharge rate increases by 7% to 8% per hour • the “Request Help” feature is not meant to be a substitute for existing local emergency systems such as 9-1-1 or 1-1-2 • some features of Group Tracker are novel and may be used in ways we did not intend; we reserve the right to remove, limit or otherwise change these features in the future

Built for live sound engineers, FOH system technicians, monitor mixers, studio engineers, and AV installers, SoundEngg is the all-in-one offline RTA spectrum analyzer, acoustic measurement console, and PA system calculator toolkit. Whether you are time-aligning delay towers at an outdoor festival, designing a cardioid subwoofer array, ringing out stage monitors, or verifying amplifier impedance loads, SoundEngg replaces a rack of hardware utilities with a rugged, zero-latency mobile workstation. 1. REAL-TIME RTA SPECTRUM ANALYZER & TRANSFER FUNCTION CONSOLE • 60FPS Real-Time Analyzer (RTA) with 1/1, 1/3, 1/6, 1/12, and 1/24 octave fractional resolution and high-resolution FFT spectrum analysis. • Live Transfer Function engine displaying Magnitude, Phasedeg, and Coherence traces for PA system tuning and crossover alignment. • 3D Waterfall Spectrogram for spotting room resonance decay, acoustic reflections, and live feedback frequencies. • Multi-Trace Snapshot Memory: Capture, store, and overlay up to 4 reference measurement curves (Traces A, B, C, D) to compare FOH and venue zones. • Custom Microphone Calibration Loader: Import standard .CAL and .TXT mic calibration files for lab-grade measurement accuracy. 2. SPEAKER DELAY & ACOUSTIC PULSE ALIGNMENT CALCULATOR • Compute exact delay tower and fill speaker alignment in milliseconds (ms), meters (m), feet (ft), and 48kHz / 96kHz DSP sample offsets. • Real-time speed-of-sound compensation using live venue temperature and relative humidity. • Acoustic Pulse Delay Finder: Measure speaker arrival time down to 0.05 ms and export a sample-accurate 48kHz Alignment Click (.WAV) track. • One-tap FOH Alignment Share Card export for sharing DSP delay specs with your system crew. 3. SUBWOOFER ARRAY & CARDIOID DISPERSION CALCULATOR • Design directional bass arrays to keep low-end energy off the stage and focused on the audience. • Supports End-Fire Arrays, Gradient Cardioid (CSA), L-Acoustics Cardioid, and d&b Cardioid Subwoofer Array presets. • Interactive 2D Polar Dispersion Map with real-time stage cancellation (dB), physical cabinet spacing, rear DSP delay, and polarity inversion readouts. 4. SPEAKER IMPEDANCE, OHM & AMPLIFIER POWER CALCULATOR • Calculate total load impedance (Ohms) and power distribution for Parallel, Series, and Series-Parallel speaker cabinet wiring. • Automatic amplifier headroom safety analysis and per-cabinet Watt (RMS) delivery calculation. 5. REFERENCE AUDIO SIGNAL & TONE GENERATOR • Precision Sine Wave frequency generator (20 Hz – 20 kHz) with interactive logarithmic sweep, fine Hz stepping, and musical note locking. • Calibrated Pink Noise, White Noise, and Polarity Pulse generator for PA system eq tuning and speaker phase checks. 6. 1/6 OCTAVE ISO EAR TRAINING LAB • Train your ears to identify surgical EQ boosts and cuts across Octave, 1/3 Octave, and pro 1/6 Octave ISO frequency bands. • Practice with Pink Noise or load custom reference audio tracks with instant Dry/Processed A/B comparison. 7. TAP TEMPO BPM & FX DELAY SUBDIVISION CALCULATOR • Rolling-average BPM tap detector with instant millisecond readouts for Quarter (1/4), Dotted, and Triplet delay subdivisions. 8. OFFLINE AUDIO PINOUT DATABASE & 100+ SYSTEM ENGINEERING GUIDES • Field wiring diagrams for XLR, Neutrik SpeakON (NL2/NL4/NL8), RJ45 Dante/AES67, PowerCON, TRS, RCA, and DB25 D-Sub. • 100+ in-depth live sound engineering guides covering line array physics, RF coordination, digital mixing consoles, and gain staging. 100% Offline-Ready on Show Site.
