摘要： There provided is a low-cost, high performance sampling rate conversion calculating apparatus which achieves both a low delay characteristic required for conversational voice data and high quality required for audio data in a concurrent manner. A first digital signal processing section outputs conversational voice data, which requires the low delay characteristic, in accordance with a sampling frequency of an output terminal (111). A second digital signal processing section outputs audio data, which requires the high quality, rather than the low density characteristic, in accordance with the sampling frequency of the output terminal (111). An adder section (107) adds the conversational voice data outputted from the first digital signal processing section and the audio data outputted from the second digital signal processing section and outputs the added data from the output terminal (111).
