About Spectrum Analyzer
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 !

Decided to play with frequency counters since I have a way to test them using a fire pager and this one detected correct with in 4hz of the actual sound

Good little free app, reasonably accurate and offers sample rates down to 25ms. Get shot of the adverts and develop the app more.
