Yes! This is my code! But it really doesn't solve any problems
because the values for matrix were generated randomly from my
mind ;) It was only experimental patch (not for CVS)!
Indeed, the docs documents only first 3 cases: 44.1, 48 and 32kHz
Any other cases are extensions which were somehow documented for
layer III and never for layers I,II. So for now it's perfectly
unclear how to decode low-sample formats (LSF) if the bit
lsf=0 in headers! (In case of lsf=1 this matrix is not used and
everything works fine for any sample rate!)
