  • Patent number: 9106993
    Abstract: In a sound processing apparatus, a likelihood calculation unit calculates an in-region coefficient and an out-of-region coefficient indicating likelihood of generation of each frequency component of a sound signal inside and outside a target localization range, respectively, according to localization of each frequency component. A reverberation analysis unit calculates a reverberation index value according to the ratio of a reverberation component for each frequency component. A coefficient setting unit generates a process coefficient for suppressing or emphasizing a reverberation component generated inside or outside the target localization range, for each frequency component of the sound signal, on the basis of the in-region coefficient, the out-of-region coefficient and the reverberation index value. A signal processing unit applies the process coefficient of each frequency component to each frequency component of the sound signal.

  • Patent number: 9070370
    Abstract: A coefficient train processing section, which sequentially generates per unit segment a processing coefficient train for suppressing a target component of an audio signal, includes a basic coefficient train generation section and coefficient train processing section. The basic coefficient train generation section generates a basic coefficient train where basic coefficient values corresponding to frequencies within a particular frequency band range are each set at a suppression value that suppresses the audio signal while coefficient values corresponding to frequencies outside the particular frequency band range are each set at a pass value that maintains the audio signal. The coefficient train processing section generates the processing coefficient train, per unit segment, by changing, to the pass value, each of the coefficient values corresponding to frequencies other than the target component among the coefficient values corresponding to the frequencies within the particular frequency band range.

  • Patent number: 7692088
    Abstract: The present invention is directed to a waveform synthesizer apparatus that synthesizes a waveform of a musical sound based on musical performance event information. In particular, a music synthesizer includes an overlap detector that detects whether a first and second musical sound overlap, and a sound length meter that determines a sound length of the first musical sound. If the first and second musical sounds overlap, the synthesizer instantly terminates synthesizing of the first sound and starts synthesizing the second sound, provided the length of the first sound does not exceed a predetermined length. If the first and second sounds do not overlap, synthesis of the first sound is terminated, and the synthesis of the second sound is initiated, if it is determined that the length of rest between the two sounds does not exceed a predetermined length, and that the first sound does not exceed a predetermined length.

  • Patent number: 7579545
    Abstract: A plurality of blocks of waveform data are stored in a memory, which also stores, for each of the blocks, synchronizing information representative of a plurality of cycle synchronizing points that are indicative of periodic specific phase positions where the block of waveform data should be synchronized in phase with another block of waveform data. Two blocks of waveform data (e.g., harmonic and nonharmonic components) are read out from the memory, along with the synchronizing information. On the basis of the synchronizing information, the readout of two blocks of waveform data is controlled using the synchronizing information. There is stored, for each of the blocks, at least one piece of synchronizing position information indicative of a specific position where the block should be synchronized with another block, and the readout of the individual blocks of waveform data is controlled so that the blocks are synchronized with each other using the synchronizing position information.

  • Patent number: 7557288
    Abstract: In a storage section, there are stored special connecting waveform data for connecting between at least two notes to be generated in succession. The special connecting waveform data contain only a waveform of a succeeding-note region of a waveform connecting portion which is provided for a continuous transition between the at least two notes and which is divided into a preceding-note region and the succeeding-note region. When a connecting tone is to be generated for connecting between two notes in accordance with acquired performance information, a tone waveform connecting between waveforms of the two notes is generated using the special connecting waveform data. With such arrangements, the waveform data of the succeeding-note region are read out without waveform data of the preceding-note region being read out, so that it is possible to reduce a time required for transition from a preceding note to a succeeding note.

  • Patent number: 7432435
    Abstract: Dynamics value is acquired intermittently at predetermined time periods, and a waveform data set for a sustain tone, corresponding to the acquired dynamics value, is specified from among waveform data sets stored in a memory. To generate a tone waveform while switching to the specified waveform, a waveform switching time is used which is modified suitably in accordance with a dynamics value variation amount from a predetermined time earlier than the current dynamics value acquisition time to the current dynamics value acquisition time. Such arrangements not only can variably control a tone, having a tone-color-variation realizing characteristic, in accordance with the input dynamics value but also permits a tone color variation with an enhanced responsiveness without causing the tone color variation to impart a feeing of undesired step-like unsmoothness, thereby synthesizing a tone with a high quality faithfully reproducing a desired tone color variation.

  • Patent number: 7396992
    Abstract: Determination is made, in accordance with acquired performance information, as to whether a crossfade characteristic should be changed or not, and a crossfade characteristic of crossfade synthesis having already been started at the time of the acquisition of the performance information was acquired are automatically changed in accordance with a result of the determination. Because the crossfade characteristic is automatically changed during the course of the crossfade synthesis, the time length of the crossfade synthesis can be expanded or contracted as compared to the time length that had been preciously set at the beginning of the crossfade synthesis, and thus, the time position of a succeeding one of rendition style modules to be time-serially combined in accordance with the acquired performance information can be allotted to a time position displaced by an amount corresponding to the expanded or contracted time.

  • Patent number: 7271330
    Abstract: There is provided a rendition style selector operable by a user to select a desired rendition style from among a plurality of rendition styles associated with a plurality of portions of tones. In response to selecting operation via the selector, a rendition style is determined which is to be applied to each desired portion of a tone. Then, performance information is output which designates a rendition style module corresponding to the determined rendition style. The module defines a waveform characteristic to provide the corresponding rendition style. According to another type of the rendition style selector, a user can collectively select a combination of a plurality of rendition styles associated with different portions of a tone. Thus, a plurality of rendition styles can be designated collectively by one selecting operation. Rendition style suitable for each portion of a tone to be generated may be determined on the basis of a performance event.
