PROBLEM TO BE SOLVED: To reduce a workload when mixing down acoustic signals of a plurality of tracks.SOLUTION: In an acoustic processing apparatus, a localization analysis section 42 analyzes localization directions &thetas;x[k, n] of acoustic signals X[1] to X[N] of N tracks, and an acoustic processing section 32 executes adjustment processing for adjusting acoustic characteristics of an acoustic signal X[n] and a localization direction &thetas;x[k, n] for each track, and a signal synthesis section 34 combines the acoustic signals Y[1] to Y[N] of the N tracks after the adjustment processing, and a priority setting section 46 sets priority P[n] of each track, and a control section 48 controls the adjustment processing for each track so that the track having the high priority P[n] is made clear than the track having the low priority P[n]. |
