SoundTools Pro

Calculator · BPM / FX (reverb recommendations) · LUFS Meter (ITU-R BS.1770) · Real-time Spectrum (Feedback Finder) · Acoustic Delay (mic-based)

Engineered for the moment the show goes live.

Soundtools Pro is the live FOH companion built for real working engineers. While the show runs, every tap counts. Every readout has to be obvious under house light. Every calculation has to come back instantly — no clutter, no menus, no internet.

Five live modules. Built for the booth.

-Calculator — Speed of sound, wavelength, delay time, SPL distance law, dB summation, room modes, Sabine RT60. The everyday math, one tap away.

-BPM / FX — Tap-tempo, reverb time recommendations, effect delays with feedback math. Sync your delay throws between songs.

• LUFS Meter — ITU-R BS.1770 with K-weighting. Integrated, short-term, momentary, true-peak. Stay in spec for broadcast, streaming, or your own loudness target.

-Real-time Spectrum — FFT analyzer with peak-hold, plus a feedback finder that tracks the resonance before it rings out.

-Acoustic Delay — Measure the actual physical delay between FOH and a mic position using pink noise and cross-correlation. No external test rig required.
