Audio tools for sound engineers and churches

Tools that work right in your browser, on a computer, tablet or phone. Your audio is analyzed on your device: it is never recorded or sent.

To tune your system and room and to find feedback

Spectrum analyzer (RTA)

See in real time which frequencies your audio has, with third-octave bars and a feedback detector. Save captures to compare before and after, and load your microphone calibration. Includes a 2-channel transfer function mode (5-minute trial).

Open the analyzer →

To know how your church sounds, with data

Sound test for your church

A guided assistant of about 10 minutes, using your phone microphone: it measures silence, spectrum, reverberation and coverage. You get a score from 0 to 100 and a free report with the main problems and how to fix them.

To understand what each equalizer does

EQ simulator

Choose a filter (bell, shelves, 12 to 48 dB/oct cuts) and see the magnitude and phase. Hear the effect with pink noise, a kick or your own audio.
