  • Patent number: 9031260
    Abstract: A band division apparatus obtains an analog low-band signal, an analog intermediate-band signal and an analog high-band signal from a digital sound signal. In the band division apparatus, a digital filter separates the digital sound signal into a digital intermediate-band signal having the intermediate frequency band while the high frequency band and the low frequency band are attenuated, and a digital low-high-band signal having a frequency band combining the low frequency band and the high frequency band while the intermediate frequency band are attenuated. A DA converter converts the digital low-high-band signal into an analog low-high-band signal. Another DA converter converts the digital intermediate-band signal into the analog intermediate-band signal. An analog filter separates the analog low-high-band signal into the analog low-band signal and the analog high-band signal.

  • Patent number: 9012756
    Abstract: The present invention may be used for producing vocal accompaniment with sound producing musical instruments. A hand operated unit may have a programmable processor, a display, a plurality of control switches and a control device. The hand operated unit may have a selection of human voiced letters in selected pitch and pronunciation characteristics stored in the programmable processor. An identification parameter correlated to a signal from a musical instrument that represents a sound produced by the use of the musical instrument may be stored with each selected human voice letter. When a selected human voice letter is activated, the hand operated unit may output a signal to a sound producing device. The hand operated unit may be connected to a foot operated unit that has multiple two-position foot switches and a pedal for use in control of pitch and sound level characteristics as well as selection of a human voice letter to be sound output.

  • Patent number: 9009052
    Abstract: Herein provided is a system for singing synthesis capable of reflecting not only pitch and dynamics changes but also timbre changes of a user's singing. A spectral transform surface generating section 119 temporally concatenates all the spectral transform curves estimated by a second spectral transform curve estimating section 117 to define a spectral transform surface. A synthesized audio signal generating section 121 generates a transform spectral envelope at each instant of time by scaling a reference spectral envelope based on the spectral transform surface. Then, the synthesized audio signal generating section 121 generates an audio signal of a synthesized singing voice reflecting timbre changes of an input singing voice, based on the transform spectral envelope and a fundamental frequency contained in a reference singing voice source data.

  • Publication number: 20150075355
    Abstract: A sound synthesizer 101 that plays a pre-determined sequence of sound notes one by one when the user taps on a touch sensitive surface 104 of the sound synthesizer 101. Different music is produced by varying the intervals between the sound notes, even from the same sequence of sound notes. The sound notes are selected according to a pre-determined scale, such as the pentatonic scale, for ease of matching to other music scales, and to reduce the disonnance between sound notes in scales such as that seen in the major scale.

  • Publication number: 20150040743
    Abstract: A voice analysis method includes a variable extraction step of generating a time series of a relative pitch. The relative pitch is a difference between a pitch generated from music track data, which continuously fluctuates on a time axis, and a pitch of a reference voice. The music track data designate respective notes of a music track in time series. The reference voice is a voice obtained by singing the music track. The pitch of the reference voice is processed by an interpolation processing for a voiceless section from which no pitch is detected. The voice analysis method also includes a characteristics analysis step of generating singing characteristics data that define a model for expressing the time series of the relative pitch generated in the variable extraction step.

  • Patent number: 8916762
    Abstract: For each one note or for each plurality of notes constituting a reference tone, a segment setting section segments a time series of actual pitches of the reference tone into one or more note segments. For each of the one or more note segments, a relativization section creates a time series of relative pitches that are relative values of individual ones of the actual pitches of the reference tone to a normal pitch of the note of the note segment. Information registration section stores, into a storage device, relative pitch information comprising the time series of relative pitches of each individual one of the note segments. The segment setting section may use musical score data, time-serially designating the notes of the reference tone, to set each of the note segments for each note designated by the musical score data, and may correct at least one of start and end points of each of the set note segments in response to user's operation.

  • Patent number: 8907196
    Abstract: A sound analysis and associated sound synthesis method is provided. A first input sound signal is received and analyzed, to determine its corresponding impulse response representative of a timbre of the input sound signal. A second input sound signal is received and processed into a form which the corresponding impulse response is susceptible to being applied, wherein the processing includes generating a “pink noise” equivalent frequency spectrum of the second input sound signal. The impulse response is applied to the processed second input sound signal to generate an output signal, wherein the output sound signal includes at least timbral nuances of the first input sound signal.

  • Patent number: 8884149
    Abstract: Systems and method for performing adaptive audio signal processing using music as a measurement stimulus signal. A musical stimuli generator may be used to generate musical stimulus signals composed to provide a stimulus with a spectrum that is substantially dense, and ideally white or pink, over a selected frequency range, so that all frequencies of interest are stimulated. The musical stimuli generator may generate melodically pleasing musical stimulus signals using music clips that include any of: a chromatic sequence, a chromatic sequence including chromatic tones over a plurality of octaves, a chromatic sequence including chromatic tones over a selected plurality of octaves, or an algorithmically composed chromatic sequence, to cover a selected frequency range. The musical stimulus signal may be generated as sound into the environment of use. An audio input picks up the sound from the environment, and a sound processor uses the received musical stimulus signal to determine a transfer function.

  • Patent number: 8878045
    Abstract: An acoustic effect impartment apparatus detects striking of any one of strings by a corresponding hammer in an acoustic piano like a grand piano, and vibrates a vibration section with a driving waveform signal obtained by synthesizing sine wave signals of the fundamental frequency and harmonic frequency of the hammer-struck string. Such vibration of the vibration section is transmitted to the keys via a soundboard and bridge of the piano. Thus, vibration is excited in the hammer-struck string by the striking with the hammer but also by the driving waveform signal, so that an acoustic effect corresponding to the driving waveform signal is imparted. Because the driving waveform signal is a simple signal using the sine wave signals corresponding to the fundamental frequency of the string, a natural feeling of the acoustic piano will not be lost even when the acoustic effect is imparted.
