Volume control and gain
The volume control structure of the STA529 consists of individual volume registers for each
channel and a master volume register that provides an offset to each channel’s volume
setting. The individual channel volumes are adjustable in 0.5-dB steps from +36 dB
to -91.5 dB. As an example, if register LVOL = 0x00 or +36 dB and register MVOL = 0x18
or -12 dB, then the total gain for the left channel is +24 dB.
When the mute bit is set to 1, all channels are muted. The volume control provides a soft
mute with the volume ramping down to mute in 4096 samples from the maximum volume
setting at the internal processing rate (around 48 kHz).
