Spectrum view is a fast real-time FFT analyzer which displays the sound waveform and its spectrum.
It offers advanced customization for both processing and rendering the spectrum.
-FFT resolution from 32 to 65536
-9 window algorithms to reduce spectrum leakage
-linear or logarithmic frequency and magnitude scales
-fast pause/resume button
-tap on frequency view to print frequency
-day or night mode

Notes:
-Amplitude value is not displayed because would not be accurate without proper calibration for your device.
-This is not a game. Please do not rate if you expected it to be so.
