Abstract
A call apparatus, a call method and a call system, are disclosed, in which the problem otherwise caused by fixed setting of the sound volume level of the BGM or the effect sound with respect to the call voice may be overcome. A decoded output of a decoder 17 (PCM data) is multiplied in a gain adjustment unit 18 with a gain coefficient k2, as the SE sound volume level as set by a user. A multiplication output of the gain adjustment unit 18 is sent to an adder 13. The decoded output of a decoder 20 is multiplied in a gain adjustment unit 21 with a gain coefficient k3, as the BGM sound volume level, as set by the user. A multiplication output of the gain adjustment unit 21 is sent to an adder 13. The adder 13 sums the multiplication outputs of the gain adjustment units 12, 18 and 21 and sends a sum output to an encoder 22.
