DCBLOCK -- remove (most of) DC bias from input signal
in RTcmix/insts/jg

quick syntax:
DCBLOCK(outsk, insk, dur, AMP) 

   p0 = output start time (seconds)
   p1 = input start time (seconds)
   p2 = duration (seconds)
   p3 = amplitude multiplier (relative multiplier of input signal)

   p3 (amplitude) can receive dynamic updates from a table or real-time control source.

DCBLOCK uses a simple one-pole/one-zero filter set to remove a DC (0 Hz) offset component in the output signal. The recursive filter equation used for this object is: where y[n] and y[n-1] are the current and previous outputs of the equation, respectively, and x[n] and x[n-1] are the current and previous sample inputs to the filter equation.



Usage Notes

DCBLOCK processes N input channels to N output channels, e.g. mono to mono, stereo to stereo, quad to quad, etc.

The sound itself should be relatively unchanged by DCBLOCK.



Sample Scores

very basic: 

   rtsetparams(44100, 2)
   load("DCBLOCK")

   rtinput("mysound.aif")

   DCBLOCK(0, 0, DUR(), 1.0)
