save data into a sound wav file.
savewave(filename,x [, rate , nbits]);
:filename a string. The path of the output wav file : :x a mxn matrix where m is the number of channels and n the number
of samples for each channel
:
save x into a wav sound file. you can transform other sound files into wav file with the sox program.
// At first we create 0.5 seconds of sound parameters.
t=`soundsec`_(0.5);
// Then we generate the sound.
s=`sin`_(2*%pi*440*t)+`sin`_(2*%pi*220*t)/2+`sin`_(2*%pi*880*t)/2;
[nr,nc]=`size`_(t);
s(nc/2:nc)=`sin`_(2*%pi*330*t(nc/2:nc));
savewave(TMPDIR+'/foo.wav',s);
