Description
App gets audio data from microphone and plots the real time spectrum in the form of a scrolling image.
App settings: • Sample Rate = the sample rate (in Hz) at which the microphone will be read. Most devices support up to 48 kHz. High-end devices support up to 192 kHz. • FFT Buffer Size = the size (in samples) of the audio buffer used to compute the FFT. Must be a power of 2, min = 128, max = 16384. Bigger value gives better frequency resolution. Smaller value gives better time resolution. • Min. Dispalyed Frequency • Max. Displayed Frequency • Gain (dB) • Displayed Time Window (in milliseconds) • Frequency Grid Step (in Hz) = will draw horizontal division lines • Time Grid Step (in milliseconds) = will draw vertical division lines moving together with the plot.

Comments on SpecStream Audio Spectrum Plot for Android
★★★★☆Padua Play· Jan 19, 2026
Checking out this app. Is it possible to display decibel levels alongside spectrum information? Thanks for making available a functional app.
★★★★★Marchantia Polymorpha· Aug 4, 2024
Simple but effective. Exactly what it should be. Only wish it would go above 4000Hz but that may be my devices' limitation I'm not sure.
★★★★★Hehe Da· Nov 29, 2023
Can you add same options? Like minimum or maximum frequency. X y-axis unit display is necessary too
★★★★★Chris Robinson· Nov 2, 2025
First spectrograph with no ads! Also instantaneous reading/display
★☆☆☆☆Robert Zinda· Dec 5, 2022
When they say it's under development they really mean it. I'm not sure what purpose this serves, as it is now it makes no sense, display is tiny and even if it was larger it wouldn't be of any use. 1 touch stops the scrolling, but that's it. Results are meaningless tiny peaks without reference. No way to enlarge. Limited to 2kHz on top of it all, makes it kind of useless for any Audio testing. Not sure who the target user is for this?
★★☆☆☆Ellen Ross· May 18, 2024
It needs more..............more!!!!! No way to enlarge, change colors, or set the frequency axes on this app. Just scans whatever it's listening to with no grid or graph 📉 behind it. (Wrong answer buzzer) Ehhhhhhh, no good.......

Horrible the second I loaded it horrible even the one I have is better than this do not install
