Audio Apparatus, and Method for Setting Number of Buses for Use in the Audio Apparatus

A computer-implemented method for setting a number of buses for use in an audio apparatus,

• the audio apparatus performing at least first mixer processing for mixing audio signals from a plurality of input channels by means of a plurality of mixing buses and then outputting resultant mixed audio signals to a plurality of first output channels and second mixer processing for mixing the audio signals from the first output channels by means of a plurality of matrix buses while treating the audio signals from the first output channels as inputs to the matrix buses and then outputting resultant mixed audio signals to a plurality of second output channels, the audio apparatus including a digital signal processing section which is shared for performing the first mixer processing and the second mixer processing, the digital signal processing section performing each of the first mixer processing and the second mixer processing by performing cross-point processes each for performing level control on an input audio signal and then adding a resultant level-controlled audio signal to one or more of the buses, a total number of the cross-point processes executable by said digital signal processing section being limited,
• said method comprising:
• a setting step of causing a user to set desired numbers of the mixing buses for use in the first mixer processing and the matrix buses for use in the second mixer processing;
• and
• a step of controlling setting, via said setting step, of the numbers of the mixing buses and the matrix buses in such a manner that a sum of a number of first cross-point processes required for the desired number of the mixing buses set via said setting step and a number of second cross-point processes required for the desired number of the matrix buses set via said setting step does not exceed a limit of the total number of the cross-point processes.
