Abstract
An apparatus and method for outputting audio signals of a portable communication device are provided. The apparatus includes a plurality of audio tables including different volume control values or tone control values, and allows a user to selectively set audio tables corresponding to each of audio paths equipped with the portable communication device. Further, the apparatus analyzes a surrounding environment during a voice call, determines the absence or presence of noise, and suitably controls a volume or a tone of audio signals based on the result of the determination before outputting the audio signals. Accordingly, the apparatus can provide an improved calling condition in various calling environments.
