Abstract
An audio signal processing apparatus performs digital-to-analog conversion to convert at least a first audio data signal having a first sampling frequency and a second audio data signal having a second sampling frequency which is different from the first sampling frequency into corresponding analog audio signals, respectively. The audio signal processing apparatus is provided with: a frequency converting device for converting the second sampling frequency of the second audio data signal into the same sampling frequency as the first sampling frequency; a digital-to-analog converting device for performing digital-to-analog conversion to convert the first audio data signal having the first sampling frequency and the second audio data signal having the converted second sampling frequency which is the same as the first sampling frequency into the analog audio signals, respectively.
