Lumisound brings spectrogram analysis, file inspection, frequency readout, and tone generation into the same pocket-sized tool.
I got tired of not having an audio toolkit in my pocket, so, I made one.
What's inside
Full 20Hz to 20kHz range with RX-inspired colour mapping. Watch frequencies unfold live as sound happens.
Import existing audio and inspect it directly. Useful for production checks, cleanup work, or quick forensic listening.
Drag across the graph for an exact readout, freeze the point in place, and inspect detail without the display slipping away.
Save captures as spectrogram images, CSV analysis data, or audio so you can inspect and share full sessions properly.
No accounts, no tracking, no cloud dependency. Audio stays on-device unless you explicitly export it.
Analyse noises, inspect mixes, check interference, and run the built-in tone generator from a focused mobile toolset.
Free to download on iPhone.
