PROBLEM TO BE SOLVED: To provide a technology of discriminating a waveform data form and efficiently coding waveform data even when part or all of a storage form of the waveform data is not recognized. SOLUTION: A waveform data form discriminating method disclosed herein includes the steps of: assuming received digital waveform data to be sample value sequences of a plurality of presetting data forms when the data are recognized to be the waveform data but the storage form of the waveform data is unknown; discriminating likely data of the waveform data by using relationships between sample values of the sample value sequences; determining a data form discriminated to be most likely waveform data as the data form of the received digital waveform data; and coding all or part of the received digital data on the basis of a result of the data form discrimination.
