Abstract
A method for controlling audio gain balance in a multi-mode communications device () includes providing () microphone audio input to the multimode communications device. The audio is supplied to an amplifier gain stage while a dynamic instantaneous energy value of the audio input is computed () when in a first operational mode such as an analog mode. A predetermined gain algorithm is processed () representing an audio input when in a second mode such as a digital mode using the energy value. The audio gain stage in the multi-mode communications device is then adjusted () so that audio gain when in the first mode substantially approximates an audio gain when in an second mode. This provides a consistent audio amplitude output when receiving the first and second modes in a radio receiver.
