Name

loadwave — load a sound wav file into scilab

Calling Sequence

x=loadwave(filename);
[x,y]=loadwave(filename);

Parameters

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)].

Description

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).

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)];
savewave(TMPDIR+'/foo.wav',s);
s1=loadwave(TMPDIR+'/foo.wav');
max(abs(s1-s))
