Sets the Compressor gain when the signal is not being compressed. The format is unsigned with 4
integer bits and 12 fractional bits.
Sets the threshold for compressor operation. The format is unsigned with 0 integer bits and 16
fractional bits.
Sets the threshold for compressor operation. The format is unsigned with 0 integer bits and 16
fractional bits.
Works in conjunction with the GAIN and THRES registers to set the compressor gain when the signal is
being compressed. The format is unsigned with 4 integer bits and 12 fractional bits. Refer to the
compression formula for more detail.
