Provided are a method and an apparatus for increasing call quality while reducing consumption of bit rates in immersive multimedia communication. A method of transmitting, by a terminal device, an audio signal to a counterpart terminal device, includes: extracting head tracking information of a user of the counterpart terminal device from a packet received from the counterpart terminal device; predicting a head direction of the user of the counterpart terminal device after a predetermined time period, based on the extracted head tracking information; generating audio output signals by combining audio input signals received via a plurality of microphones, based on the predicted head direction; and transmitting information about the predicted head direction and a sound frame in which the audio output signals are compressed, to the counterpart terminal device.
