Spectrum Analyzer

Visualizzazione suono in forma d'onda (dominio del tempo) e spettro (dominio della frequenza).

Free application for visualizing sound coming to your phone's microphone. Program shows both waveform (time domain) and frequency spectrum (frequency domain) in real-time. User can pause, pan, zoom-in, zoom-out graphs and take snapshot to phone's gallery.

Since v.1.0.7, you can choose FFT window size either 1024 or 2048. A higher window size gives more accurate frequencies but using a small window size is faster and recommended on low spec phone. You can choose two histogram plotting styles (area plot or bar graph) and see dominant frequency from the graph.

Hope you enjoy !
