Abstract:
A sound apparatus for synthesizing M channels of output voice signals from m channels of input voice signals, comprising:first providing means for providing n channels of input voice signals at a frame period that is arranged with n number of timeslots to accommodate the n channels of the input voice signals; rearranging means for rearranging the timeslots so as to increase the number of the timeslots from n to m within the frame period, and for distributing the n channels of the input voice signals to the rearranged timeslots so as to create m-n number of free timeslots within the frame period; second providing means disposed separately from the first providing means for providing at most m-n channels of input voice signals in addition to the n channels of the input voice signals; allocating means for allocating at most the m-n channels of the input voice signals to the m-n number of the free timeslots so as to accommodate within the frame period the m channels of the input voice signals provided from both of the first providing means and the second providing means; and mixing means for mixing the m channels of the input voice signals with one another by time-division manner of the m channels to produce the M channels of the output voice signals.
