You typically don't, block size is set in Faust architecture file.
It is not really the block size but the number of samples current
compute() was called with.
Might vary depending on how it is called.
If you really want to do some sort of block processing, you should use
@ operator,
rdtable and rwtable functions.
Mind you, Faust is not well suited to block processing at the time,
it's a stream processing language.
