Parameters

• filename : a string. The path of the wav file to be loaded
• x : a matrix one line for each channel
• y : vector

Examples

// At first we create 0.5 seconds of sound parameters.
t=soundsec(0.5);
// Then we generate the sound: a two channels sound.
s=[sin(2*%pi*440*t);sin(2*%pi*350*t)];
