摘要： An electronic signal processor for processing signals includes a complex first filter, one or more gain stages and a second filter. The first filter is characterized by a frequency response curve that includes multiple corner frequencies, with some corner frequencies being user selectable. The first filter also has at least two user-preset gain levels which may be alternately selected by a switch. Lower frequency signals are processed by the first filter with at least 12 db/octave slope, and preferably with 18 db/octave slope to minimize intermodulation distortion products by subsequent amplification in the gain stages. A second filter provides further filtering and amplitude control. The signal processor is particularly suited for processing audio frequency signals. Related methods include filtering the input signal with an input filter of the second or third order high pass type, amplifying the filtered signal and further filtering the amplified signal with a low pass filter, which may be of the second order type.

摘要： A karaoke amplifier is constructed for amplifying an audio signal to sound a karaoke performance while processing the audio signal according to a value of a control parameter to acoustically control the karaoke performance. An analog operating member is manually operable to set an initial analog value of the control parameter. An analog/digital converter converts the initial analog value into a corresponding initial digital value. A receiver receives correction data from an external data source. A memory memorizes the received correction data. A calculator arithmetically treats the initial digital value according to the correction data retrieved from the memory to calculate a corrected value of the control parameter. A signal processor processes the audio signal according to the corrected value of the control parameter and amplifies the processed audio signal to sound the karaoke performance which is acoustically modified according to the corrected value of the control parameter.

摘要： An adaptive audio signal compression computer system corrects multiple input audio streams, such as digital multichannel audio streams from various audio sources, for equalization deficiencies caused primarily by attenuation factors experienced by a listener's human ear. A compression stage (filter stage) adaptively compresses (filters) an input audio stream by selecting the ear response data that includes a plurality of selectable sets of filter coefficients wherein each set of filter coefficients corresponds to an inverse audible listening response curve for a predetermined audio volume level. When available from an audio source, the system provides audio source type data to an adaptive compression stage and also generates a compression control signal in response to the source type data to control the compression. Listening environment data is also used to generate control parameters for the compression stage so that compression can be dynamically varied based on changing surrounding environmental circumstances.

摘要： A musical device controller and system that includes an electric guitar having strings and a pick-up that produces an electrical music signal from vibrations of the strings, a musical effect generator that receives the electrical music signal from the guitar and alters the musical signal to produce a musical effect, a guitar pick for striking the strings to cause the vibrations, and a force sensing device mounted on the guitar pick. The force sensing device has a pair of electrical leads connected to the musical effect generator, and a pressure sensitive material that is formed of a semiconductor material having microprotrusions or a pressure sensitive ink. The electrical leads are in contact with the pressure sensitive material such that electrical resistance between the pair of leads incrementally and repeatably decreases as a force applied to the force sensing device incrementally increases. The musical effect generator is responsive to, and varies the musical effect according to, the resistance between the pair of leads.

摘要： A musical instrument amplifier system (FIGS. 1 and 2) with a frequency selective crossover circuit (10) using passive band pass filters (36, 44) to separate the amplified signals from the power amplifier (14) of an amplifier system (12) into low frequency signals on an output connector (42) for a specially adapted bass audio speaker (38) while the higher frequency signals are applied to another speaker (46). The crossover circuit (10) is selectively connected with the normal speaker output (24) in lieu of the speaker (38) to add frequency crossover capability to any amplifier system. In another musical instrument amplifying system (88), the crossover circuit (FIG. 4, 122, 124, 130, 132) is internal to an amplifier system (90) and produces preamplified low frequency signals on a special output terminal (102) for power amplification by an external power amplifier (94) while the preselected low frequency signals are blocked from the internal power amplifier (118) so it produces only the relatively middle and high frequencies at the normal speaker output connector (98). The preselected low frequency signals bypass a special effects section (112) so that special effects is selectively only produced by the internal power amplifier (118) in the relatively middle and high frequency range, while the power of the external bass power amplifier (94) is separately adjustable from the adjustment to the power level of the internal power amplifier (118). When the external power amplifier is disconnected, the internal high pass filter (124) blocking low frequency signals to the internal power amplifier (118) is automatically removed to allow full frequency amplification by the internal power amplifier (118).
