Abstract:
A waveform data structure includes a plurality of types of frames having different data sizes. Each of the plurality of types of frames includes an auxiliary information area and a data area. The auxiliary information area includes an area for storing common effective-bit length data for a section of waveform samples, and an area for storing an identifier for identifying one of the plurality of types of frames. The data area is an area for storing extracted waveform samples which are extracted from the waveform samples based on the common effective-bit length. The number of the extracted waveform samples is determined based on the common effective-bit length.

Claim (Index 13):
A sound generation method of an electronic musical instrument, the electronic musical instrument comprising (i) a memory having a waveform data structure, the waveform data structure being configured by one of at least first and second frame types, each of the first and second frame types being determined based on a result of whether or not a first value is equal to a second value, the first value being a value of a common effective-bit length calculated based on compressed waveform samples corresponding to the first frame type, the second value being a value of the common effective-bit length calculated based on the compressed waveform samples corresponding to the second frame type, frame sizes of the first and second frame types being different from each other, each of the first and second frame types including an auxiliary information area and a data area, the auxiliary information area including an area for storing one of the first value and the second value and an area for storing an identifier for identifying one of the first and second frame types, the data area being an area for storing waveform samples which are extracted from the compressed waveform samples in accordance with the one of the first value and the second value, and a number of the waveform samples being determined based on the one of the first value and the second value and the one of the first and second frame types which is identified by the identifier, (ii) a musical-instrument-performance input section, (iii) a hardware processor, and (iv) a speaker, and the method comprising:\n performing, by the hardware processor, an instructing process of instructing music generation according to playing operations input to the musical-instrument-performance input section, and an obtaining process of obtaining necessary waveform samples from the memory in response to the instructing process; and producing, by the speaker, music sound based on waveform data obtained by decompressing the waveform samples obtained from the memory.
