Method for controlling multi-mode audio gain balance

A method for balancing microphone audio gain in a communications device transmitting analog and digital voice comprising the steps of:

• providing at least one microphone audio input to the communications device;
• computing an instantaneous energy value of the audio microphone input when in a digital voice mode;
• smoothing the instantaneous energy value using at least one filter for dampening peak values;
• processing at least one gain algorithm representing an analog microphone audio gain using the instantaneous energy value;
• and
• adjusting at least one gain stage of the communications device based on the processed at least one gain algorithm so the at least one microphone audio input when in a digital mode substantially approximates the at least one microphone audio input when in an analog mode.

A method for balancing the audio output in a two-way radio receiver that operates in both first and second voice modes comprising the steps of:

• providing at least one speaker input;
• determining a desired voice gain algorithm when in the first voice mode;
• determining an energy value of the at least speaker input when in the second voice mode;
• using a filter to normalize the energy value;
• processing the desired voice gain algorithm using the energy value from the second voice mode;
• and
• dynamically adjusting at least one speaker gain stage using the processed desired voice gain algorithm such that the speaker gain when in the second voice mode substantially approximates the microphone gain when in the first voice mode.
