Constructor parameters to initialize the CVSD decoder. The default values are modeled after the Bluetooth standard and should not be changed, except by an advanced user.

Parameters:

min_step	Minimum step size used to update the internal reference. Default: "10"
max_step	Maximum step size used to update the internal reference. Default: "1280"
step_decay	Decay factor applied to step size when there is not a run of J output 1s or 0s. Default: "0.9990234375" (i.e. 1-1/1024)
accum_decay	Decay factor applied to the internal reference during every interation of the codec. Default: "0.96875" (i.e. 1-1/32)
K;	Size of shift register; the number of output bits remembered by codec (must be less or equal to 32). Default: "32"
J;	Number of bits in the shift register that are equal; i.e. the size of a run of 1s, 0s. Default: "4"
pos_accum_max	Maximum integer value allowed for the internal reference. Default: "32767" (2^15 - 1 or MAXSHORT)
neg_accum_max	Minimum integer value allowed for the internal reference. Default: "-32767" (-2^15 + 1 or MINSHORT+1)
