A portable terminal comprising: a touch screen; a sound output device comprising one or more speakers; at least two microphones (162-1,162-n); a memory configured to store instructions; and at least one processor, wherein the instructions are configured, when executed, to cause the at least one processor to: obtain information related to directions of a plurality of sound sources by receiving a plurality of sound signals including a first sound signal and a second sound signal via the at least two microphones (162-1,162-2); display a plurality of indications (91, 92, 93, 94,95) representing one or more sound sources around the portable terminal, and an image positioned at a centre in relation with the plurality of indications (91, 92, 93, 94, 95) on the touch screen, each of the indications of the plurality of indications (91, 92, 93, 94, 95) having a distance to the centre; receive, on the touch screen, a user gesture input; characterized in that: if the user gesture input is a drag input with respect to the image, toward an indication of the plurality of indications (91, 92, 93, 94, 95), determine that the user gesture input indicates a sound-selection direction from the received drag input, and output a sound corresponding to the sound-selection direction through the one or more speakers, if the user gesture input is a flick input to a specific range after a touch and hold input to the image, determine that the user gesture input indicates a sound source-selection range, select at least one sound source within the indicated sound source-selection range and output the sound of the selected at least one sound source. a touch screen;
