Abstract:
1. An audio apparatus for performing a predetermined signal processing on voice and audio signals, comprising: a first sampling frequency conversion circuit for converting digital voice signals into first converted signals sampling processed at a frequency, n×fs, as a multiple of a first predetermined sampling frequency fs with n being a first integral number larger than unity, and for outputting first resultant signals, said digital voice signals previously being sampling processed at the first predetermined sampling frequency fs; a second sampling frequency conversion circuit for converting digital audio signals into second converted signals sampling processed at a frequency, N×Fs, as a multiple of a second predetermined sampling frequency Fs with N being a second integral number larger than unity, and for outputting second resultant signals, said digital audio signals previously being sampling processed at the second predetermined sampling frequency Fs; a third sampling frequency conversion circuit for converting said first resultant signals output from said first sampling frequency conversion circuit into third converted signals sampling processed at the frequency, N×Fs, and said second resultant signals output from said second sampling frequency conversion circuit into fourth converted signals sampling processed at the frequency, n×fs, and for outputting third resultant signals; a first digital processing circuit for performing a predetermined digital processing operation on said digital voice signals converted into said first converted signals sampling processed at the frequency, n×fs, by said first sampling frequency conversion circuit and on said digital audio signals converted into said fourth converted signals sampling processed at the frequency, n×fs, by said third sampling frequency conversion circuit; and a second digital processing circuit for performing another predetermined digital processing operation on said digital audio signals converted into said second converted signals sampling processed at the frequency, N×Fs, by said second sampling frequency conversion circuit and on said digital voice signals converted into said third converted signals sampling processed at the frequency, N×Fs, by said third sampling frequency conversion circuit.
