    摘要： In some embodiments, a method applying reverberation to audio from at least one client of a set of clients which share a virtual environment, including by asserting position data and at least one input audio stream to a server, selecting (in the server) a reverberation filter for each input audio stream in response to the position data and generating wet audio by applying to the input audio an early reverberation part of the selected reverberation filter. Typically, a client applies a late reverberation filter to the wet audio using metadata from the server. In other embodiments, a server selects a reverberation filter for application to audio in response to position data, asserts the audio and metadata indicative of the filter, and a client applies the filter to the audio using the metadata. Other aspects are systems, servers, and client devices configured to perform any embodiment of the method.

    摘要： Percussion sounds and damped sounds from a first fundamental tone producing unit (100) provided to correspond to individual parts of a playing drum set are received by a microphone such as a pick-up microphone, and electric sounds from the microphone are tone-regulated by a tone regulating unit (26) with their analog sounds kept unchanged and digital conversion not involved. Then, a reproducing unit (34) reproduces the sounds based on the output sounds from the tone regulating unit (26). Because of the absence of such operations as digital conversion processing, signal transmission via a photocoupler or the like, and selection and reproduction of pre-recorded sounds, the player does not recognize the time lag between a striking operation and the production of a played sound and uses, as fundamental tones, striking sounds and damped sounds produced when the first fundamental tone producing unit (100) is struck, thereby enabling reproduction faithful to a delicate striking technique of the player.

    摘要： A designating mechanism generates filtering designation data, which designate the contents of filtering, reverberating designation data, which designate the contents of reverberation, and characteristics data, which express the combined contents of filtering and reverberation. A parameters generating mechanism generates filtering parameters expressing filtering characteristics, and generates reverberating parameters expressing reverberation characteristics. A readout device reads out a first operating algorithm, which designates filtering designation data, and a second operating algorithm, which designates reverberating designation data, from a memory mechanism wherein a plurality of operating algorithms are stored. A computing mechanism creates a digital filter having characteristics corresponding to filtering parameters, based on the first operating algorithm, creates an operating unit having reverberation characteristics corresponding to reverberating parameters, based on the second operating algorithm, operates this digital filter and this operating unit in a time shared manner, and processes filtering and reverberation in parallel.

    摘要： A resonance tone generation apparatus 20 is applied to an electronic musical instrument DM having a tone generator for generating a musical tone signal indicative of a piano sound in accordance with a tone generation instruction signal having a key number n, and a plurality of output means adapted for externally outputting a musical tone signal. The resonance tone generation apparatus 20 has a plurality of resonance tone generation circuits 30 (n) each of which is assigned a different key number n, retrieves a musical tone signal indicative of a musical sound of the piano, generates a musical tone signal indicative of a resonance tone imitating a tone of a string of the piano resonated by the musical sound of the piano indicated by the retrieved musical tone signal, and supplies the generated musical tone signal to the plurality of output means. Each of the resonance tone generation circuits 30 (n) has a resonance circuit 40 (n) which has a plurality of resonance frequencies corresponding to the assigned key number n, and generates a musical tone signal indicative of the resonance tone imitating the tone of the string of the piano resonated by the musical sound of the piano indicated by the retrieved musical tone signal, and a panning setting circuit 50 (n) which generates a plurality of musical tone signals which are to be supplied to the plurality of output means, respectively, and each of which indicates a different resonance tone in which a tone volume of the resonance tone indicated by the musical tone signal generated by the resonance circuit 40 (n) is changed in accordance with the assigned key number, and supplies the generated musical tone signals to the plurality of output means, respectively.
