soundsec generates a vector of samples for t seconds at frequency freq Hz. samples=soundsec(t [,freq]) t a 1-by-1 matrix of positive real numbers, the time length to sample. freq a 1-by-1 matrix of positive real number, the frequency of samples per second. default value is 22050 Hz Generates a vector coding time from 0 to t seconds at sampled rate freq. Samples are always generated to fit in [0,t[ (excluding upper bound). Value 0 for either t or freq return an empty matrx playsnd analyze
