<p>Embodiments of the invention relate generally to electrical and electronic hardware, computer software, wired and wireless network communications, and wearable computing and audio devices for communication audio. More specifically, disclosed are an apparatus and a method for processing audio signals to include spatially modulated message audio signals as a portion of a monaural signal. In some embodiments, a method includes receiving a message for a loudspeaker. The method can determine whether an audio signal is in communication with the loudspeaker and a type of a message of the message. Message audio for the message can be spatially modulated as a function of the type of message. A mono-spatial audio signal can be formed based the audio signal and the spatially-modulated message. Thus, a monaural audio signal can be modulated to generate mono-spatial effects for presenting the messages.</p> |
