摘要： Methods and apparatus to classify media based on a pitch-independent timbre attribute from a media signal are disclosed. An example apparatus includes means for accessing a media signal; and means for: determining a spectrum of audio corresponding to the media signal; and determining a timbre-independent pitch attribute of audio of the media signal based on an inverse transform of a complex argument of a transform of the spectrum.

摘要： With reference to FIG. 7a the present invention relates to transducer apparatus (200) for use with a reed instrument (201) having an air chamber (15) forming a resonant cavity whose resonance characteristics are controlled by opening and closing of tone holes (17A, 17B) connecting the air chamber to the exterior of the reed instrument. The transducer apparatus comprises attachment means (202) for releasably securing the transducer apparatus to a mouthpiece (201) of the reed instrument in place of a reed. A reed replacement section (203) has a housing with an abutment surface for abutting a surface part of the mouthpiece which would be abutted by a reed secured to the mouthpiece. An air passage extends through the housing of the reed replacement section (203) from an air inlet (211) through which a player of the instrument can blow to an air outlet (213) through which air blown by the player is delivered to atmosphere, without passing through the air chamber (15) within the reed instrument. A speaker (208) is supported by the housing and delivers sound to the air chamber (15). An air chamber microphone (209) is supported by the housing and receives sound in the air chamber (15). An electronic processing unit (204) has: an excitation unit (101) which produces an excitation signal for driving the speaker (208); a processor (102) for receiving a measurement signal produced by the microphone and for detecting from the measurement signal a musical note played by the instrument; a synthesizer (220) for generating an electronic signal embodying a musical note which corresponds to the detected musical note; and output means (103) for transmitting the musical note generated by the synthesizer to a receiver external of the transducer apparatus. The invention also relates to a system for representing the sounds of a reed instrument having the components of the transducer apparatus, to an electronic system for determining a musical note played by a reed instrument having the components of the transducer apparatus and to a method of practising playing of a reed instrument comprising use of the components of the transducer apparatus.

摘要： Provided is an electrophonic chordophone system (20) comprising sensor (24) configured to be operatively responsive to respective strings of a guitar (22). The system (20) also includes non-transitory processor-readable storage means (26) which contains first and second user-configurable tonal formats (28) and (30). Also included is processor (32), arranged in signal communication with the sensor (24) and storage means (26), and adapted to associate a melody group of notes producible by the strings with the first tonal format (28) in a one-to-one mapping or direct correlation, and to associate a control group of notes producible by the strings with the second tonal format (30) in a one-to-many mapping or indirect correlation. Also included is a synthesiser (34), arranged in signal communication with the processor (32), and configured to produce both the first and second tonal formats simultaneously in substantial real-time. The first tonal format (28) is actuatable via the melody group of notes and the second tonal format (30) is dynamically selectable via the control group of notes and also actuatable via the melody group of notes. In this manner, a melody is producible via the first tonal format (28) with a dynamic backing track producible via the second tonal format (30), all using one guitar (22).

摘要： The present invention relates to the field of audio recognition, in particular to computer implemented note recognition methods in a gaming application. Furthermore, the present invention relates to improving latency of such audio recognition methods. One of the embodiments of the invention described herein is a method for note recognition of an audio source. The method includes: dividing an audio input into a plurality of frames, each frame having a pre-determined length, conducting a frequency analysis of at least a set of the plurality of frames, based on the frequency analysis, determining if a frame is a transient frame with a frequency change between the beginning and end of the frame, comparing the frequency analysis of each said transient frame to the frequency analysis of an immediately preceding frame and, based on said comparison, determining at least one probable pitch present at the end of each transient frame, and for each transient frame, outputting pitch data indicative of the probable pitch present at the end of the transient frame.

摘要： Systems and methods for a digital instrument are described, for example to simulate or be used in conjunction with a stringed instrument. A sensor system detects the deflection of one or more strings of the digital instrument, produces a measurement of the detected deflection, correlates the measurement to a musical note, and produces at least a portion of digital output based upon the musical note.

摘要： A method and an information processing apparatus to generate a digital score file of a song are described. The information processing apparatus includes processing circuitry. The processing circuitry is configured to obtain a candidate audio file satisfying a first condition from audio files of unaccompanied singing of the song without instrumental accompaniment. The processing circuitry is configured to divide the candidate audio file into valid audio segments based on timing information of the song, and extract pieces of music note information from the valid audio segments. Each of the pieces of music note information includes at least one data set of a music note in the song. The data set includes an onset time, a duration, and a music note value of the music note. The processing circuitry is configured to generate the digital score file based on the pieces of music note information.
