Abstract
A technique includes providing a sidetone path to generate sidetone content in response to audio data and disabling at least part of the sidetone path during an active mode of a radio. The technique includes storing the sidetone content in an outgoing audio buffer that is operational during the active mode of the radio and establishing a delay in the sidetone path to prevent the outgoing audio buffer from being depleted of the sidetone content during the active mode of the radio.
