Abstract: The device relates to a circular electronic musical instrument having a keyboard with keys which produces polyphonic musical notes. The device is an organ which covers at least one octave of musical notes. The octaves are aligned in bands of concentric rings located on the top of the instrument. Each band of keys may contain one octave of notes. Notes in a first octave are next to or nearby identical notes in a second octave to make popular chords and songs easy to play. Notes may be played simultaneously which are octaves apart with one hand due to proximity of all the keys. A hand may extend over a centrally located loudspeaker and be used to vary the loudness and produce vibrato effects. A small overlay having information may be easily placed on the top of the keyboard to assist in learning songs by number, color, or other visual aids.

Abstract: The sound-processing apparatus of the present invention generates plural frequency data by decoding plural encoded sound data and applying inverse quantization. Each of the frequency data are subjected to sound-processing and then synthesized into one single frequency data. Transformation processing from frequency domain to time domain is applied to the synthesized single frequency data so as to generate sound data in time domain so as to reduce computation amounts of decoding process.

Abstract: Disclosed is a method for modifying the frequency response of a wood panel within an acoustical structure such as a studio or concert hall. The modification is imparted by exciting the wood paneling with acoustic energy. Frequency response is the measure of a system's spectrum response at the output to a signal of varying frequency (but constant amplitude) at its input. The acoustic energy includes at least one excitation frequency, which is preferably in the audible spectrum (20 to 20,000 Hz). The use of acoustic energy from the remote source provides non-contact excitation of the wood paneling. In one embodiment, the acoustic energy is at least one sound wave which comprises at least one resonant frequency of the wood paneling, at least one acoustic mode of the wood paneling, at least one discrete broadband frequency, a composite frequency (including multiple broadband frequencies, white noise and pink noise) or any combination thereof.

Abstract: Apparatus and methods are described for facilitating improving health of a user. In accordance with some applications, a first physiological variable, which is indicative of a voluntary action of the user, is received. A second physiological variable, which is not entirely under the direct voluntary control of the user, is received. Responsive to the first and second variables, the second physiological variable is changed in a desired manner, by using circuitry to direct the user to modify a parameter of the voluntary action, by generating an output signal. Other applications are also described.

Abstract: A system and method for musical collaboration in virtual space is described. This method is based on the exchange of data relating to position, direction and selection of musical sounds and effects, which are then combined by a software application for each user. The musical sampler overcomes latency of data over the network by ensuring that all loops and samples begin on predetermined temporal divisions of a composition. The data is temporarily stored as a data file and can be later retrieved for playback or conversion into a digital audio file.

Abstract: A performance apparatus 11 extends in a longitudinal direction to be held by a player, and is provided with an acceleration sensor 23. CPU 21 of the performance apparatus 11 gives a sound source unit 31 of a musical instrument unit 19 an instruction (note-on event) to generate a musical tone. CPU 21 generates a note-on event indicating a sound-generation timing represented by a time when an acceleration-sensor value of the acceleration sensor 23 exceeds a first predetermined value and thereafter has decreased to a value less than a second threshold value ?, which is less than a first threshold value ?, and gives the musical instrument unit 19 the generated note-on event to generate a musical tone.

Abstract: From analog music information in which the sounds of a plurality of musical instruments are mixed, sound data corresponding to the register of the reproduced sound of a bass guitar and sound data corresponding to the register of the reproduced sound of a drum are extracted using a band-pass filter. A drive pulse with a low frequency is generated within the periods of data sections in which the former sound data reaches a predetermined level or higher, and a drive pulse with a high frequency is generated within the periods of data sections in which the latter sound data reaches a predetermined level or higher. A vibrating body in a vibration mechanism unit is resonated by two drive pulses with frequencies, thereby causing vibration according to the reproduced sound of music.

Abstract: A tone generation control device sets a setting value for crosstalk cancellation. When vibration generated in a target striking surface is detected, a value indicative of the degree of crosstalk that the target received from comparison striking surfaces is calculated. The calculated value is displayed regardless of whether a tone generation instruction has been output. Meanwhile, setting values used for crosstalk cancellation for the respective striking surfaces are also displayed. Therefore, the user can observe and understand as to whether the vibration generated at the target is vibration caused by crosstalk received from the comparison striking surface, such that setting values to be used for crosstalk cancellation can be suitably set.

Abstract: A resonance tuner receives and digitizes an analog signal in response to a resonance of a structure thereby creating a plurality of time samples. A series of the time samples are buffered upon burst detection. A power spectrum is estimated by computing a Time-To-Frequency-Transform of the series of time samples and a magnitude of each of the resulting frequency samples is squared. At least one subset associated with at least one spectral peak is selected from the frequency samples. Each spectral peak has at least one sample with a sufficient magnitude and being spectrally adjacent to any other sample in another spectral peak by less than a threshold. A fundamental spectral peak is determined in a fundamental subset including a spectral peak with a sample at the lowest frequency greater than zero. The fundamental spectral peak has the sample with the largest magnitude within the fundamental subset.

Abstract: The present invention provides a complementary bifurcated circuit to process and optimize music digitally with high fidelity yet with wireless elements. In a particular embodiment, an audio transducer in close proximity to a musical instrument or vocalist's mouth transforms audible music to analog electrical signals, which are digitized and then filtered to remove external noise at the frequencies of alternating current as well as internally generated noise. A FPGA encoder optimizes the signal's latency and formats the signal for wireless transmission, which is then accomplished with a transmitter and receiver. A transmitter control interface programs one or more of the digital encoder, digital processor, FPGA encoder and wireless transmitter.
