Displays real time graphics representing the sound captured by the microphone.

Features & Capabilities

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.

User Reviews

Spectrogram is praised for its usefulness in audio analysis and is usable on some devices, with positive feedback across several reviews. However, users report major performance problems (slow, GPU-memory related), missing essential controls (FFT window size, zoom, time/frequency window), and visual quality issues (jittery/pixelated rendering). Some also note imperfect audio quality and inaccurate spectrum readings. Overall a mixed but critical reception.

Pros

Excellent app for analysis of audio/spectrum.
Works well and is usable on some devices (e.g., Note 8).
Positive overall reception across multiple reviews (e.g., 'nice work').

Cons

Severe performance and resource issues: very slow, laggy, and GPU memory errors.
Lack of essential spectral analysis controls: FFT window size/zoom/time and frequency window adjustments.
Visual rendering issues: jittery drawing and pixelation.
Audio/spectrum accuracy issues: not great audio quality and mis-detection (e.g., whistles triggering multiple frequencies).

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
