声データ入出力装置。[Claim for Utility Model Registration] The input/output mode is set by the input/output instruction means, and in the input mode, analog audio data is sampled by a sample hold circuit, converted to digital data by an A/D converter, and the data is converted into digital data. In an audio data input/output device, the digital data is stored in a storage means by a writing means, and in an output mode, the digital data is read from the storage means by a data reading means, and is converted into analog data by a D/A converter and outputted, when in an input mode. a period specifying means for specifying the sampling period of the sample-and-hold circuit; and a header writing means for writing a header for identifying the specified sampling period in the storage means in correspondence with the input audio data in the input mode. a header detection means for detecting a header corresponding to the audio data read out in the output mode; a header detection means for setting the sampling period of the sample and hold circuit to a period specified by the period designation means in the input mode; 1. An audio data input/output device characterized by comprising period control means for setting the read period of the data reading means to a period corresponding to the header detected by the header detection means.
