Vibrato Patents (Class 84/706)
  • Patent number: 10652668
    Abstract: A method performs frequency distortion of an audio signal. The audio signal is divided at at least one division frequency into a low-frequency band and a high-frequency band. A frequency-distorted signal is generated through respectively different distortions of frequencies for the high-frequency band and for the low-frequency band. The division frequency is selected such that it is located between two neighboring tones of a given tonal system.

  • Patent number: 7991621
    Abstract: An apparatus for processing an encoded signal and method thereof are disclosed, by which an audio signal can be compressed and reconstructed in higher efficiency. An audio signal processing method includes the steps of identifying whether a type of an audio signal is a music using first type information, if the type of the audio signal is not the music signal, identifying whether the type of the audio signal is a speech signal or a mixed signal using second type information, and if the type of the audio signal is determined as either the speech signal or the mixed signal, reconstructing the audio signal according to a coding scheme applied per frame using coding identification information. If the type of the audio signal is the music signal, the first type information is received only. If the type of the audio signal is the speech signal or the mixed signal, both of the first type information and the second type information are received.

  • Patent number: 6873708
    Abstract: Since the prior-art is based upon analog circuitry, it uses sinusoidal frequency and/or amplitude modulation to simulate a rotating speaker at a reasonable cost. This invention uses a process based upon theoretically derived frequency modulation (FM) and experimentally measured amplitude modulation (AM) to simulate the rotating speaker. The main FM equation is based upon the Doppler effect and is equal to one over one plus a sinusoidal velocity coefficient. The main AM equation has a much narrower peak than sinusoidal modulation. This invention also contains several novel methods to control the angular velocity of the speakers, including changing the horn's speed dependent upon the original audio, modeling the speaker's acceleration to allow the physically realistic transitions between angular velocities, and adding noise to simulate natural variations in rotation. The digital apparatus that implements this invented process includes a digital processor and memory.

  • Patent number: 6369312
    Abstract: A method for expressing a vibratory music that may be felt as a piece of music for a human being in according with an acoustic vibration in an auditory region and/or a body sensible vibration or a body sensible acoustic vibration and an apparatus therefor are obtained. A signal about 16 Hz to 150 Hz (sound compass C0 to D3) in a frequency band of a body sensible vibration is used and what is composed and arranged in combination of strength, length, frequency, waveform and overlap of the vibration on a time basis, based upon a constant theory is expressed as a vibratory music. Transducers 5 are assembled into a backrest, a seat portion and a leg portion of a reclining seat, respectively. Speakers are mounted on a head portion. The transducers for outputting the sound vibrations are provided on both arm rests.

  • Patent number: 5333203
    Abstract: A preamplifier device employing electron tubes wherein the preamplifier has tremolo/vibrato circuits independent from reverb circuits allowing continuously variable control of either tremolo or vibrato effects simultaneous with continuously variable control of the reverb effect. A mixer control for controlling the level of reverb and a tone control is provided. Connections are provided for external switches used to disable any one of the above effects.

  • Patent number: 5060270
    Abstract: A reverberation circuit comprises an amplifier, attenuation circuit, a feedback component, and a delay circuit. The amplifier, delay circuit, and feedback component form a feedback loop. The amplifier amplifies an input signal supplied to an input terminal and outputs an amplified signal to the delay circuit. The output of the delay circuit is fed through a feedback component back to the amplifier. The feedback component controllably varies the feedback amount of the delayed signal to the amplifier in accordance with the desired depth of reverberation. An attenuation circuit is placed in the feedback loop, or before or after the feedback loop. The attenuation circuit selectively attenuates the level of specific frequency component of a signal passing therethrough whose frequency may be different depending on the depth of reverberation or feedback amount.
