The biquads are implemented in a direct form-I architecture. The direct form-I structure provides a separate delay
element and mixer (gain coefficient) for each node in the biquad filter.
The five 26-bit (3.23) coefficients for the biquad are programmable via the I2C interface.
The following steps are invovled in using a loudness biquad with the volume comprensation feature:
1. Program the biquad with a loudness filter.
2. Program 0x26 (1/G) and 0x28 (scale).
3. Enable volume compensation in register 0x0E.

Subchannel Preprocessing
A subchannel has three input multiplexers that can select from the bass management output, the downmix
output, or the channel-6 input multiplexer output.
Register 0x21, bits (9:8) determine the submultiplexer selection, defined in Table 4.
