Friture is a program designed to analyze audio input in real-time.
Friture displays audio data in several widgets, such as a scope, a spectrum analyzer, or a rolling 2D spectrogram.

SignalView is a stereo sound visualization VST3 plugin. It has a time domain view and a frequency domain view with optional linear or logarithmic display. There is also a sonogram(waterfall) view to see trends in the spectrum.


Spectrum Spectogram Analyzer was designed with accuracy and easy of use in mind. It can be used for monitoring or measuring environmental sound or noise; help tuning instruments; timing short sound events; and educational purpose.


Audio Spectrum Analyzer is the most popular Android alternative to Signalizer.
WaveSpectra is a tool that (FFT fast Fourier transform) an audio signal as input and sound card, the Wave file, and displays the frequency components (spectrum) in real time.

Real-time audio spectrum analyzer with reasonable frequency resolution across the the entire frequency spectrum.
