The present invention provides an audio control device and an audio control method capable of promptly controlling a desired sound source, by simply selecting the sound where the sound state should be adjusted among multiple sounds, without displaying the sound state of multiple sounds on a display for identifying. An audio control device according to the invention includes a cross-key manipulation detection module 1 that receives various input manipulations; a plurality of generating units 14a to 14e that generate a sound having a different sound source; and CPU 12 that controls the sound state generated by the plurality of generating units 14a to 14e, wherein the cross-key manipulation detection module 1 controls the sound state of the selected first generating unit among the plurality of generating units 14a to 14e, wherein CPU 12 generates a sound having a sound state which is controlled by the input unit in the first generating unit, generates a sound having a sound state which is different from that of the first generating unit in the other generating units.
