4.3.7 Offset
The offset is a user-selectable gain or volume control. When using the STC it is advised to
use the offset to tune the output volume instead of the regular volume controls. The offset is
located before the attenuator block, ensuring that the output power limit (limiter threshold) is
never exceeded (
). On the other side, the traditional volume control is located after
the STC attenuator, thus a wrong setting of this control could nullify the STC effect.
Each sub-band has its own and independent offset. Its range is [0, +48] dB with a 0.25 dB
step (
).

4.3.8 Stereo
link
The stereo link feature allows applying the same attenuation to the corresponding band of
each channel (i.e. band 0 left channel and band 0 right or band 1 left channel and band 1
right channel). This should help to prevent image shifting that could occur when individually
compressing each channel and causing a volume mismatch between left and right.
When the stereo link is active, the proper attenuation for each band is independently
computed, then the highest one for each band is applied (
).
