PROBLEM TO BE SOLVED: To generate various kinds of artificial sounds through control by software while saving the memories. SOLUTION: The device is provided with a first buffer means which stores compressed audio streams, a memory means which beforehand stores the compressed and prescribed audio streams, a switching means which conducts switching of the output of the first buffer means and the output of the memory means, an extending means which extends the compressed audio streams outputted from the switching means, a second buffer means which stores uncompressed audio digital data outputted from the extending means, a D/A converting means which converts the audio digital data outputted from the second buffer means into analog signals, an output device which amplifies the analog signals outputted from the D/A converting means and outputs audio signals, and a control means which controls the extending means and the switching means and also controls the sampling frequency of the D/A converting means. |
