the out-of-the-box ogg vorbis lib e.g. chooses the amount of samples it 
dispenses based on the number of frames it had decoded. if you want to read 
blockwise, that is: based on a blocksize that _you_ want, you have to chop up 
and merge the blocks that the lib gives you.

if a lib guarantees to always mix as many samples as i require, it is 
out-of-the-box ready for blockwise streaming, even with small blocks of data.
