Assignment 1

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
