Tone Gen Pro vs EngineerTact

Generate audio signal of different shapes with many parameters and options. You can generate frequencies up to 20 kHz of audio signal. If you are curious student about sound after a physics class, music instruments hobbyist/professional, a teacher, or a professional in audio equipment, this app is for you ! You can generate: - Single type signal (sinusoidal, square, noise, etc) - Sweep (chirp) signal (linear or exponential) - Click: ON-OFF sine wave with any duty cycle and ON frequency - Merged sound of any number of tones or sweeps

EngineerTact is an offline field toolkit for engineers, land surveyors, RF technicians, and field operators across all domains — land, sea, and air. KEY FEATURES: • WGS84 Geodetic Coordinate Conversion — Convert between Geodetic (Lat/Lon/Alt) and ECEF (X/Y/Z) using the Bowring iterative algorithm. Real-time ENU Local Tangent Plane target tracking with bearing and range. • RF & Radar Calculator — Compute Free Space Path Loss (FSPL), Radar Line of Sight (4/3-Earth model), first Fresnel Zone radius, and signal wavelength. All calculations run on-device. • Mission Brief Planner — Build complete field mission briefs with route distance (Haversine), bearing in degrees and NATO mils, estimated time of arrival, and RF link margin. Save and reload briefs on-device. • Aerospace & Maritime Converter — Convert speed (knots, km/h, m/s, Mach), altitude (ft, m, FL), pressure (hPa, inHg, psi), and ISA atmospheric parameters with full unit coverage. • Number Base & Data Converter — Convert between decimal, hexadecimal, binary, and octal. IEEE 754 float analysis. Bit-width calculator. • Formulas & Reference — Full mathematical reference for FSPL, WGS84 geodesy, Haversine, radar horizon, Fresnel zone, and NATO unit standards. All calculations are performed entirely on-device. No network connection, no account, no tracking, no ads. Designed and engineered by Fırat Bozkaya.
