Does anyone know the algorithm that would take a stream of sampled sound
,shift it 180 deg in phase and spit it back out again?

ie   sound -> a/d -> dsp to shift phase -> d/a -> sound

(it would seem from the nature of the problem that a simplistic analog
 circuit to do this might be possible... some sort of RC net... if anyone
 know if this is possible, PLEASE make it known.)

Thanks
