Description

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.

v1.1.5

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.

Developer Response

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.

v1.1.5

It's exactly what I needed, but I need to zoom in to 0-100Hz range, which is not possible, so I can't use it.

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.

Developer Response

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.
