When capturing sound, we need to be able to plot the both the amplitude and frequency of the sound for each point in it time the recording. This can being easily achieved if we simply measure the amplitude of the wave at a set interval of time.… Read More »http://learnlearn.uk/binary/wp-content/uploads/sites/11/2017/01/high-amplitude-300x149.png
