Method and apparatus for controlling sound signal output

The present invention relates to a method and apparatus for controlling sound signal output. The method for controlling sound signal output of a terminal which matches a receiver identifier to a corresponding sound signal adjustment parameter and stores the matching result according to the present invention comprises the following steps of: providing a receiver selection interface capable of selecting either a list of the receiver identifier or receiver identifier included in the list of the receiver identifier; receiving one receiver identifier through the receiver selection interface; converting a digital sound signal into an analogue sound signal by applying the sound signal adjustment parameter corresponding to the receiver identifier; outputting the analogue sound signal. According to an embodiment of the present invention, an optimal sound can be provided for a user by providing an appropriate sound signal for a receiver.
