Справка Scilab >> Sound file handling > soundsec

soundsec

generates a vector of samples for t seconds at frequency freq Hz.

Calling Sequence

samples=soundsec(t [,freq])

Arguments

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

Description

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

Examples

// At first we create 0.5 seconds of sound parameters.
t=soundsec(0.5);

// Then we generate a pure A4 = 440Hz sine
s=sin(2*%pi*440*t);
analyze(s,200,600,22050);
