MATLAB basics (Due by noon on January 31st via email)
Re-create the following waveform plots and spectrograms the files r1.wav and r2.wav from the Sonic Visualiser Tutorial, create the following plots, replicating all of the axis labels and titles. Also submit your MATLAB code.
Waveforms
R1
R1 – Zoomed in to 15–25 seconds, -0.5–0.5 amplitude
R2
R2 – Zoomed in to 0–10 seconds, -0.8–0.8 amplitude
Spectrograms
R1 – Using a window size of 0.064 and a corresponding 1/4 hop size
R1 – Using a window size of 0.064 and a corresponding 1/4 hop size, zoomed in to 0–5000 Hz
R1 – Using a window size of 0.016 and a corresponding 1/4 hop size, zoomed in to 0–5000 Hz
R2 – Using a window size of 0.064 and a corresponding 1/4 hop size
R2 – Using a window size of 0.064 and a corresponding 1/4 hop size, zoomed in to 0–5000 Hz
R2 – Using a window size of 0.016 and a corresponding 1/4 hop size, zoomed in to 0–5000 Hz
