Improve audio loading progress reporting

Browse source 
Even without the animation the reported progress was an average of 1.5
blocks behind the actual progress, and with the animation it was two
blocks behind. Assuming constant-speed audio decoding it should now be
nearly accurate (it still ignores that the last block may be smaller
than the rest).
