SoundMaster Pro

Sound Master is the pocket toolkit for live sound engineers and installers — all the everyday acoustics tools in one fast, focused app. SIGNAL GENERATOR Sine, white noise, pink noise and log sweep. Dial the exact frequency in seconds, with a real-time engine that changes pitch live. SPECTRUM ANALYZER Real-time FFT through the microphone, with Current, RMS and Peak curves and 1/1 to 1/12 octave views. Read the room and catch problems before the audience does. RT60 & SYSTEM RESPONSE Measure a room's reverberation time (EDT, T20, T30) and check a PA's response with a sweep + mic — fast field checks to spot big holes and peaks. ACOUSTIC DELAY FINDER Align speakers by measurement, not by ear: a continuous test signal and cross-correlation find the exact time offset between two or more speakers, with noise-averaging to stay accurate even in a loud room. Get the delay to add, in milliseconds and meters, in seconds. SPEAKER SETUP & DELAY ALIGNMENT Cardioid and end-fire sub calculators, delay-tower alignment, and full 1D/3D multi-system alignment with a 2D top/side view. Includes official L-Acoustics preset and amplifier-capacity data. ACOUSTICS GUIDE SPL/distance and delay calculators plus practical reference sheets, always at hand. — Works offline, no account needed — Clean, dark, fast interface — English & French Free to try.
