摘要： Multiple kernel-mode audio processing modules or filters are combined to form a module or filter graph. The graph is implemented in kernel-mode, reducing latency and jitter when handling audio data (e.g., MIDI data) by avoiding transfers of the audio data to user-mode applications for processing. A variety of different audio processing modules can be used to provide various pieces of functionality when processing audio data.

摘要： An extensible kernel-mode audio (e.g., MIDI) processing architecture is implemented using multiple modules that together comprise a module graph. The module graph is implemented in kernel-mode, reducing latency and jitter when handling audio data by avoiding transfers of the audio data to user-mode applications for processing. In one embodiment, the audio processing architecture is readily extensible. A graph builder can readily change the module graph, adding new modules, removing modules, or altering connections as necessary, all while the graph is running.

摘要： A method for generating electromagnetic (EM) music through excitation of an EM Musical Instrument is provided. An input queue, comprised of three sub-queues, receives three input audio queues. An EM excitation signal is generated based on the received input audio queues. The EM excitation signal is applied to the EM Musical Instrument. A measured response is generated, based on a response of the EM Musical Instrument to the EM excitation signal. Various time marks are marked in the measured response. Selected portions of the measured response are discarded based on particular time marks, generating a newly measured sample set. The newly measured samples are joined to a previously measured sample set of an output queue based on alignment of time marks. Various alternate embodiments and supporting systems are also provided.

摘要： Disclosed is a stringed instrument with embedded DSP modeling capabilities to model an acoustic stringed instrument. The stringed instrument has a body and a plurality of strings and each of the plurality of strings is respectively coupled to a pickup to detect a vibration signal for each string. An A/D converter converts the detected vibration signal of a string into a digital string vibration signal. A DSP is located within the body of the stringed instrument to process the digital string vibration signal and to implement an acoustic modeling system to process the digital string vibration signal in order to emulate a corresponding string tone of one of a plurality of selectable acoustic stringed instruments. Acoustic modeling includes acoustic string and body modeling, microphone placement modeling, and pick-sound modeling. The emulated acoustic digital tone signal is then converted to analog form for output to an amplification device.

摘要： A music apparatus is constructed for processing a music tone signal in response to a clock signal at each sampling period. In the music apparatus, a clock generator generates the clock signal. A signal processor is operable in synchronization to the clock signal for time-divisionally processing a plurality of music tone signals through a plurality of channels within one sampling period. A clock controller is operative during a supply duration allocated within one sampling period for supplying the clock signal to the signal processor from the clock generator to thereby operate the signal processor, and is operative during other than the supply duration within one sampling period for stopping the supplying of the clock signal to the signal processor to thereby suspend the signal processor.

摘要： A reverberation generating apparatus is designed for applying a reverberation effect to an acoustic signal for output based on sampling data representative of an impulse response waveform. In the apparatus, a first convolution operating section convolutes the acoustic signal with sampling data corresponding to an initial period of the impulse response waveform so as to generate an initial acoustic signal. The initial period of the impulse response waveform is determined from a point of impulse sound emission to a point after a lapse of a specified time. A second convolution operating section convolutes the acoustic signal with sampling data corresponding to a selected period of the impulse response waveform so as to generate an additional acoustic signal. An attenuation operating section recurrently outputs the additional acoustic signal while attenuating the additional acoustic signal so as to generate a late acoustic signal. An output section synthesizes the initial acoustic signal and the late acoustic signal for the output.
