Soundscope Pro is a real-time audio analyzer with two faces, and one purchase covers iPhone, iPad and Apple Watch. No subscription, no ads, no account, and no audio ever leaves your device. TWO WAYS TO SEE SOUND • Analog: a third-octave analyzer built like a piece of hardware. Thirty-one columns on the IEC center frequencies from 20 Hz to 20 kHz, each one a ladder of discrete LED segments running green, yellow, orange and red, with a peak-hold segment that falls slowly. Slow averaging to start with, so the face swings the way a rack unit does. • Precision: a clean laboratory display. Octave, 1/3-octave or 1/6-octave bars with thin peak caps, the fine FFT spectrum drawn over them as a smooth curve with a soft fill, a logarithmic frequency axis gridded at 20, 50, 100, 200 and 500 Hz and 1, 2, 5, 10 and 20 kHz, and a labelled dB grid.
