【實用音樂app】Frequency Splitter|最夯免費app-綠色工廠好玩App

Frequency Splitter is an audio tool which displays raw sound data from your microphone (which has an adjustable amplitude) and also splits that data into the most relative frequencies that it determines. This is done using the Discrete Fourier Transform method. You can choose the time span to view the frequencies in (similar to an oscilloscope) and set a frequency filter so unwanted frequencies aren't grabbed by the application. The two most relative frequencies are drawn to the screen by using the chosen time constant and a trigonometric algorithm.
