Abstract: A first contact and a second contact are provided at each of a plurality of keys, and are successively closed in accordance with a key press operation. On the basis of respective closed sense signals from the first contact and the second contact, a duration from when the first contact is closed until the second contact is closed is counted as a first count value and then a duration after this counting has ended is counted as a second count value. An attainment duration value and the second count value are compared, and when a predetermined condition is satisfied, a control signal is outputted. When this control signal is received, sound emission information instructing an emission of a sound by a sound emission controller is sent. The sound emission information includes touch information based on the first count value.

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.

Abstract: For respective sampling data of waveform data of sounds to be coded, a prediction residual value is calculated as sampling residual data, and an effective bit length is calculated from this residual waveform data. Then, for the effective bit length data, a maximum effective bit length among processing targets is generated as common effective actual data, and coded data in which this common effective actual data and information indicating the common effective bit length are arranged in a predetermined configuration format are generated. The information included in the coded data is analyzed and each of the plurality of the common effective bit information is extracted. Then, waveform data of the sounds are decoded by performing inverse linear prediction processing from an analysis result on the residual waveform data decompressed by performing bit extension which adds a portion other than the common effective bit length.

Abstract: A double buffer (four pages×2 system) constituted by a DSP program buffer (D-RAM) and a prefetch program buffer (D-RAM) is provided, and burst access is performed collectively for four samplings from the prefetch program buffer (D-RAM). When this burst access is performed, a decline in performance caused by latency that occurs each time an external memory (DDR-SDRAM) is accessed is avoided by accessing with sequential addresses.
