## What is SoundEngg?

SoundEngg is the ultimate, offline-ready field companion designed specifically for live sound mixing engineers, system technicians, monitor mixers, and AV crews. 

RTA Spectrum Analyser, aligning delay lines, or wiring up a rack in the middle of a festival stage with zero cellular coverage? SoundEngg runs 100% offline, keeping essential calculations and references right in your pocket.

--- PROFESSIONAL FIELD TOOLS ---

- SPECTRUM ANALYZER (RTA):
Perform precise ISO-band analysis, peak tracking, and monitor frequency feedback in real-time. Calibrated for fast diagnostic checks on site.

- ACOUSTIC TIME & DELAY CALCULATOR:
Compute phase alignment offsets compensated for local temperature. Toggle between metric (meters/Celsius) and imperial (feet/Fahrenheit) instantly.

- CARDIOID SUBWOOFER ARRAY CALCULATOR:
Design cardioid spacing, end-fire arrays, and broadside configurations in seconds. View physical wavelengths and delay settings instantly.

- CONNECTOR PINOUT REFERENCES:
High-fidelity wiring guides for XLR, SpeakON (2-pole & 4-pole), TRS, RJ45, PowerCON, and DMX. No more searching manuals in the dark.

- SPEAKER IMPEDANCE & LOAD CALCULATOR:
Calculate speaker impedances (series and parallel loads) to ensure your amplifiers match and stay out of protect mode.

- SIGNAL GENERATOR:
Inject clean sine waves, white noise, pink noise, and custom frequency sweeps directly to your system for line-checks and room diagnostics.

- TAP TEMPO SUBDIVISIONS:
Find exact milliseconds and BPM subdivisions for delay units and effects parameters on the fly.

- EAR TRAINING FREQUENCY GAME:
Sharpen your ears on the road. Practice identifying frequencies, bands, and dB cuts to improve your live mixing adjustments.
