#X text 7 35 Rzero_rev~ filters an audio signal (left inlet) via a

|
one-zero real filter \, whose coefficient is controlled by a creation

argument or by an audio signal (right inlet). The impulse response
|
|
is that of "rzero" reversed in time.;

#X text 14 230 The action of rpole_rev~ is:;

#X text 71 251 y[n] = -a[n] * x[n] + x[n-1];

#X text 6 302 The transfer function is H(Z) = -a + Z^-1.;

|

and other raw filters are provided for situations which the user-friendly

ones can't handle. See Chapter 8 of http://crca.ucsd.edu/~msp/techniques
|
|
for an introduction to the necessary theory.);
