About this app
This app uses a Fast Fourier Transform (FFT) to analyse the sound picked up by the device's microphone in real time.
It then displays the results in the form of a spectrogram. Try whistling some notes to see the effect.
Also featuring a frequency and musical note detector, displayed at the top left of the screen.

Works for two seconds, then says the GPU is not fast enough to draw a spectrogram. It needs some options to lower the settings so it can be ran on even somewhat lower end devices. Seems like it would be good otherwise, but I wouldn't know.

Hi Aren, thanks for your feedback. This is a known issue on some mid to low powered GPUs. Will look into it for the next release. Sorry for your experience.

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.

Thankyou Danilo for your review of our app, its much appreciated! Yes to be able to change the scale and zoom are a couple of features we'd like to work on in a future release.

Excellent app for analysis of audio whether it's music or sounds in a shop it would be better if it allowed you to change the colors for different locations.
