Meter, analyzer, system calculators and show records for live sound engineers. iPhone and iPad.
What's in it
- Tonight: the current show's venue, stage plot, input list, checklists and ring-out notes on one screen.
- Measure: SPL meter (A/C/Z, Leq, max, peak, calibration), analyzer (octave, 1/3-octave, FFT), tone generator, noise exposure.
- System: delay and alignment, delay towers, SPL and coverage, speaker load, cable runs, power and circuit planning.
- Sound: dB maths, gain structure, frequency and wavelength, mic spacing, reverb time, room modes.
- Show: bands with input lists, monitor mixes and stage plots (PDF and CSV), show log, ring-out notes, gear inventory, checklists.
Safety
Loud sound causes permanent hearing loss. A phone microphone is not a calibrated instrument; SPL readings are estimates and not for compliance. Start test signals low. Mains power distribution must be planned and connected by qualified people to local electrical code.
