Implement a system that analyses audio in real time and displays energy at each frequency evolving as a function of time. Frequency resolution and rate at which energy changes are estimated should be adjustable parameters in your code. Audio input should be via the PC micin/line-in. In addition, your system should also be able to accept an audio file (.wav format, 16kHz sampling rate) as input and produce the required display as the audio is played in real time via loudspeakers/headphones Platform: MATLAB B
