Abstract: A method and device may color or modify the tone or sound quality of audio input signals. A processor such as a DSP, may apply two or more filters to the audio input signal, each filter comprising a set of filter coefficients. The processor may combine finite impulse response (FIR) filters of the two or more filters into a power-saving filter. A speaker or sound emitter may emitting an output audio signal from the filtered audio input signal. The output audio signal has a different tone quality than that of the input audio signal.

Abstract: A soundhole accessible musical instrument control platform mounted inside the body of a musical instrument requires no physical alterations to the instrument, allowing the user convenient and ergonomic access to the control platform through the soundhole while using the musical instrument. The control platform includes a circuit platform, mounted inside the instrument with adhesives, separably attached to a mounting bracket. Control detents and markings are easy to feel and to read and thus provide feedback for control position and the relative degree of effect. The controls are surrounded by a cosmetic bezel that hides the actual mounting mechanism and circuitry. Any combination of controls, circuitry, and sensors may be used. Power is either provided onboard or offboard. An output connector may be integrated into the circuit platform or via an endpin jack.

Abstract: A violin shoulder rest that facilitates the optimal positioning of a violin relative to a violin player's body for increased comfort and reduced physical stress, and facilitates the optimal positioning of a microphone relative to the violin to achieve the desired volume and tonal qualities of the sound produced by the instrument. The violin shoulder rest includes an elongated base conformable to a violin player's body, clamping members coupled at opposing ends of the base for clamping the shoulder rest to a violin, and a securement mechanism to secure the respective clamping members to the base. The violin shoulder rest accommodates at least one electrical signal input, and amplification circuitry or other signal processing circuitry for pre-amplifying or otherwise processing the electrical signal input. The violin shoulder rest is configured to mount a positionable microphone subassembly adjacent a respective signal input connector.

Abstract: A transducer for a stringed musical instrument utilizes a coaxial structure. An electromechanical film tape is disposed about an inner, electrically conductive core. An outer conductor is formed about the electromechanical film tape. The electromechanical film tape may be provided as a piezoelectric polymer film or an electret film having a permanent electric charge, and is formed about the inner core by wrapping or braiding. Prior to being disposed about the inner core, the film tape may be polarized through the application of a direct current through the film to substantially align the electrical domains in the film. The transducer is configured for placement underneath the saddle in a bridge of a stringed musical instrument.

Abstract: A system and a method of measuring, decomposing, processing and uniquely recombining forces and vibrations acting on stringed musical instruments (SMI). The system utilizes a digital signal processor and reproduces the musical sound characteristics of an acoustic instrument into high fidelity electrical signals for amplification, processing and/or filtering and reproduction of musical sounds by uniquely exploiting, through measurements and subsequent signal processing, the vector nature of string excitation forces (SEF) and body vibrations of stringed musical instruments. A signal processing system of the current invention also utilizes a plurality of sensors, each responsive to at least one of force, displacement, velocity or acceleration indicative of the vibrational energy of the strings, to produce a sensor signal vector, which is then processed and transformed by a plurality of re-creation filters into a transformed signal vector, and then resynthesized into an output signal.

Abstract: A transducer for a stringed musical instrument utilizes a coaxial structure. A thin layer of a piezoelectric polymer material is extruded about an inner, electrically conductive core. An outer conductor is formed about the piezoelectric polymer material. Polarization of the piezoelectric polymer material is accomplished in conjunction with the extrusion process. The piezoelectric polymer material has an optimized thickness for consistent responsiveness across a desired range of input stimuli, and is capable of maintaining the integrity of the transducer over time. The transducer configured for placement underneath the saddle in a bridge of a stringed musical instrument.
