    Figure 315. Soft Volume and Loudness Compensation Block Diagram
    Figure 315 is a more detailed block diagram of soft volume and loudness compensation, and includes the I2C
    subaddress commands that control volume and loudness compensation. Volume control is accomplished using three
    I2C subaddresses—volume control, mute/unmute control, and volume slew rate control.
    Volume control in the TAS3103 applies a linear gain. The volume commands issued via I2C subaddresses 0xF2,
    0xF3, and 0xF4 (monaural channels 1, 2, and 3 respectively) are signed 5.23 format numbers. These commands are
    applied to mixers, whose other input port is the audio data stream. The mixer output is the product of the audio data
    stream and the volume command. Examples of volume command settings are given below.
    Volume Command = 0x3580B07 = 0011_0.101_1000_0000_1011_0000_0111 = 6.6878365
    Volume Command = 0x01F0000 = 0000_0.001_1111_0000_0000_0000_0000_0000 = 0.2421875
    Volume Command = 0xCD6EFFE = 1100_1.101_0110_1110_1111_1111_1110 = 6.3208010
    The volume control range is 0 =
    ∞ to 223 = 138.47 dB to 24 223 = 24.08 dB. Volume control is achieved by means
    of a 5.23 format gain coefficient that is applied to a linear mixer. The volume gain setting realized, for a given volume
    gain coefficient is:
    Gain = 20log (Volume_Gain_Coefficient)
