About
Microphone output can be captured in real-time by using the associated import dialog button.
The microphone data is converted to a spectrum image (Fourrier Transform) in real-time from left to right.
The time / frequency resolution of the resulting spectogram can be controlled by increasing or decreasing the Mic. FFT size in the import dialog Mic pane.
