  • Patent number: 10365890
    Abstract: A data sonification system for representing a plurality of channels of numerical information is described wherein the rate of the periodic modulation is itself used as a vehicle for carrying information of at least one component of the multidimensional numerical data. The data sonification system includes a plurality of audio waveform generator elements. Each of the audio waveform generator elements generates an associated audio frequency waveform. Each audio frequency waveform has an audio frequency parameter and at least one timbre modulation parameter having a settable value. The timbre modulation parameter affects the timbre of the audio waveform. The data sonification system includes a mapping element for associating aspects of multidimensional numerical data with the timbre modulation parameter of each audio frequency waveform. The mapping element sets the value of the timbre modulation parameter in response to multidimensional numerical data and/or periodic modulation.

  • Patent number: 7638704
    Abstract: Synthesis of time-varying MIDI control signals useful in creating spatial perturbation, chase effects, new forms of rich musical timbre modulation, spatially-distributed timbre constructions, and other types of sonic animation. Phase staggered multi-channel MIDI-format control signals are created using one or more low frequency oscillators, each with a plurality of phase shifting elements. Control signal waveshapers may be included in the control signal synthesis chain. In an exemplary embodiment, frequency and phase parameters are adjustable, with values that may be recalled from stored program control and/or modulated in real-time by incoming MIDI control signals. In another exemplary embodiment, each outgoing control signal additionally may be independently assigned a selectable waveshape, which is determined by values that may be recalled from stored program control and/or modulated in real-time by incoming MIDI control signals.

  • Patent number: 7504575
    Abstract: An intonation training device for training musicians in just intonation. As disclosed, the device is a pocket-sized portable device with an audio output and a user interface which includes an LCD display and a device such as a push button for selecting an item from a menu. When the device is turned on, the LCD display indicates a key and the device emits a sustained pure chord in the key. The user can use the menu item selection device to select another key and the training device then continuously emits the chord in the just scale for that key. The selected key appears in the LCD display. Implementations disclosed include an implementation that employs stored samples of the chords, an implementation in which the chords are generated from waveforms, and an implementation in a portable pocket-sized multimedia asset player.

  • Patent number: 7365263
    Abstract: An intonation training device for training musicians in just intonation. As disclosed, the device is a pocket-sized portable device with an audio output and a user interface which includes an LCD display and a device such as a push button for selecting an item from a menu. When the device is turned on, the LCD display indicates a key and the device emits a sustained pure chord in the key. In a preferred embodiment, the pure chord is a perfect fifth in the just scale for the key. To train his or her intonation, the user then plays a sequence of notes in the key, adjusting his or her intonation while playing to eliminate beats between the note being played and the chord being emitted by the training device. In other embodiments, the device may emit a third in the just scale for the key. The user can use the menu item selection device to select another key and the training device then continuously emits the chord in the just scale for that key. The selected key appears in the LCD display.

  • Patent number: 5194684
    Abstract: Variable frequency sawtooth waveforms are often utilized as an excitation signal in a digital musical synthesizer. A problem exists at lower sampling rates in such systems due to an aliasing problem which occurs at frequencies near the Nyquist rate. Low pass filtering may be utilized to mask this problem; however, low pass filtering is very time consuming to implement in a ditigal signal processor. The method and apparatus of the present invention reduces the upper harmonic content of a sawtooth waveform by proportionally converting the sawtooth waveform to a triangle waveform in response to variations in the frequency of the sawtooth waveform. This is accomplished by adding a selectable offset to the sawtooth waveform and then taking the absolute value of the resultant waveform. By restoring this waveform to a zero offset, the sawtooth waveform excitation signal will be converted to a triangle waveform having a substantially reduced upper harmonic content.
