PROBLEM TO BE SOLVED: To perform high-grade audio process with a reduced power by causing a calculating means such as a DSP for performing a reproducing program for reproducing high-quality audio information to also execute an audio processing program for performing an echo process and a sound quality conversion process. SOLUTION: When a DSP 16 simultaneously executes a reproducing program and an audio processing program, there is the possibility that process capacity of the DSP 16 becomes insufficient. Therefore, the performance of the audio processing program is started, and the processing capacity of the DSP 16 required for performing the reproducing program is reduced. Thus, even a relatively low speed DSP 16 can simultaneously execute the reproducing program and the audio processing program, and cost and consumed power of an entire device are reduced. Due to the execution of the audio processing program, a voice from a microphone 14 receiving a process, such as sound quality conversion, is added to an accompaniment created by execution of the reproducing program, and outputted to a D/A converter 17. |
