Claim Text:
1. A volume control method comprising: receiving a master volume control signal corresponding to a master volume control attenuation; providing the master volume control signal to a pre-digital signal processing volume control; receiving an input signal by the pre-digital signal processing volume control; determining a pre-digital signal processing first attenuation in the pre-digital signal processing volume control based on the master volume control signal; applying the first attenuation to the input signal in the pre-digital signal processing volume control before performing digital signal processing of the input signal to create a first attenuated signal; digitally processing the first attenuated signal to produce a processed signal; applying the master volume control attenuation to the processed signal in the master volume control to create an output signal; and providing the output signal to produce audio signals; wherein the first attenuation is applied before the input signal is provided before Automatic Gain Control (AGC) processing.
