RSIGIN

RSIGIN - read signal (random position)

Usage:

RSIGIN SIG REV L POS K D

Inputs:

SIG	name of shell-wave-item
REV	0, YES|1)
L	frame length in samples (>=4)
POS	read position (center of frame, 0..signal length-1)
K	amplification factor
D	differentiation factor (0..1)

Outputs:

Xi	signal of channel i (L samples)
SR	sampling rate in Hz

Function:

This atom implements a signal-frame read function with random positioning. It can be used in signal processing circuits connected to an interactive graphic or control-dialog. In each cycle the signal around the position POS is read. To allow updates of POS, the input should be connected to a shell-value-item. The value of the output SR is set during the initialization. The input REV can be used to reverse the signal in time.
