Comments on Spectrogram for Android

★★★★★ Deeanna Verile · Jan 29, 2022

Very good___. And has anyone here put cave.sound.14.ogg in spectrogram

★★★★☆ Glitchurix · Feb 17, 2020

It's good and all, but it needs to be faster and register higher hertz than what it currently has. It also said that my GPU wasn't fast enough.

★★★★★ Danilo Leite · May 31, 2026

Very simple, simply works, no ads, no menu, nothing. Beautiful. I'd love to change some settings like the scale of frequency (zoom and log/linear/etc.). And the Rms etc. to tune for better time VS freq resolution.

★☆☆☆☆ ̷ ̴ ̸ɢ̸ʟ̶ɪ̸ᴛ̶ᴄ̶ʜ̷ ̶ ̶ · Jan 2, 2019

Badly implemented. Wastes GPU memory, practically doesn't work and stops with "Not enough free GPU memory"

★★☆☆☆ Ryan Miller · Nov 25, 2021

Screen drawing is quite jittery, no option to change window size, many other features are missing that the people who use this type of software would need to make it desirable
