Problem Set 4 Mask


Supplement to a problem set on simple psychoacoustic masking, Markoff processes, entropy, and grading, entropy coding, error correction, and data compression. This MATLAB code performs a simple psychoacoustic masking test by creating bandlimited noise around 1000 Hz and a single sinusoid at frequency f with amplitude A. It then plays the noise alone, and then the noise plus the sinusoid.
