Description of the audioprocessor part
TDA7410ND
5.3
Softstep Volume
When volume level is changed often an audible click appears at the output. The root cause
of those clicks could be either a DC offset before the volume stage or the sudden change of
the envelope of the audio signal. With the Softstep feature both kinds of clicks could be
reduced to a minimum and are no more audible (see Figure 4).
