See:

/pd/doc/3.audio.examples/B09.sampler.loop.smooth.pd

The [-~ 0.5]--[*~ 0.5]--[cos~] construction makes an windowed "envelope" 
  from the output of the [phasor~]. This ensures that the endpints of 
the table are always zero. However, it also modulates the amplitude of 
the sound coming out to some extent. But it is the most "systematic" way 
of setting your table boundaries to zero.
