4 results about "Pitch range" patented technology

An electronic musical instrument includes: a plurality of keys that include at least first keys corresponding to a first pitch range and second keys corresponding to a second pitch range; and at least one processor, configured to perform the following: causing a syllable position in a phrase that is digitally synthesized for output not to be advanced no matter how the second keys in the second pitch range are operated while a key operation in the first pitch range is being continuously maintained; and causing the syllable position to advance every time a key operation in the second pitch range is performed while none of the first keys in the first pitch range is being operated.

A method includes detecting whether there is a very short pitch lag in a speech or audio signal that is shorter than a conventional minimum pitch limitation using a combination of time domain and frequency domain pitch detection techniques. The pitch detection techniques include using pitch correlations in a time domain and detecting a lack of low frequency energy in the speech or audio signal in a frequency domain. The detected very short pitch lag is coded using a pitch range from a predetermined minimum very short pitch limitation that is smaller than the conventional minimum pitch limitation.

An electronic device comprising circuitry configured to separate by audio source separation a first audio input signal into a first vocal signal and an accompaniment, and to transpose an audio output signal by a transposition value based on a pitch ratio, wherein the pitch ratio is based on comparing a first pitch range of the first vocal signal and a second pitch range of the second vocal signal.

The present invention provides an automatic arrangement method, an automatic arrangement device, and a computer program product, which can produce arrangement data that is easy to play and has a reduced number of simultaneously sounding notes from musical piece data. The present invention determines an outer sound symbol, and the outer sound symbol is the highest in pitch among notes that have substantially the same sounding start time in a melody part obtained from the musical piece data. A melody part from which an inner sound symbol is deleted is produced, and the inner sound symbol starts to sound during the sounding period of the outer sound symbol and is low in pitch. For each pitch range in which the pitch range of one octave is staggered by one semitone, a candidate accompaniment part in which the root notes of each chord of the chord data of the musical piece data are arranged to sound at their sounding timing is produced, and an accompaniment part is selected therefrom. The arrangement data obtained from the melody part and the accompaniment part can be set as arrangement data that is easy to play and has a reduced number of simultaneously sounding notes.
