load a sound wav file into scilab
x=loadwave(filename);
[x,y]=loadwave(filename);
:filename a string. The path of the wav file to be loaded : :x a matrix one line for each channel : :y vector as [data format, number of channels, samples per second
per channel, estimate of bytes per second needed, byte alignment of a basic sample block, bits per sample, length of sound data in bytes, bytes per sample (per channel)].
:
Reads a .wav sound file into Scilab as a matrix. If y is given, it is filled with information about the samples (See the message sent by loadwave).
// 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)];
`savewave`_(TMPDIR+'/foo.wav',s);
s1=loadwave(TMPDIR+'/foo.wav');
