Spectrolite

Spectrolite visualizes sound as real-time spectrograms with linear, mel, and constant-Q scales. It covers the full range of human hearing and supports intuitive touch panning and zooming to explore detail. Real-time adjustments to gain, Q, and other parameters apply to both past and future signals, enabling interactive analysis.

The Pro in-app purchase unlocks grids and scales for time, frequency, and amplitude, adds a spectrum view, and introduces tap-to-measure so Spectrolite becomes a precise audio measurement tool for frequencies, pitches, amplitudes, and durations.
