    摘要： For at least one music piece, a storage section (30) stores tone data of each of a plurality of fragments segmented from the music piece and stores a first descriptor indicative of a musical character of each of the fragments in association with the fragment. Descriptor generation section (12) receives input data based on operation by a user and generates a second descriptor, indicative of a musical character, on the basis of the received input data. Determination section (14) determines similarity between the second descriptor and the first descriptor of each of the fragments. Selection section (16) selects the tone data of at least one fragment from the storage section (30) on the basis of a result of the similarity determination by the determination section. On the basis of the tone data of the selected at least one fragment, a data generation section generates tone data to be outputted.

    摘要： An improved control structure for music synthesis is provided in which: 1) the sound generation provided to the adaptive function mapper (501) allows for a greatly increased degree of control over the sound produced; and 2) training of the adaptive function mapper (501) is performed using an error measure, or error norm, that greatly facilitates learning while ensuring perceptual identity of the produced sound with the training example. In one embodiment, sound data is produced by applying to an adaptive function mapper (501) control parameters including: at least one parameter selected from the set of time and timbre space coordinates; and one parameter from the set of pitch, delta pitch, articulation and dynamic. Mapping is performed from the control parameters to synthesis parameters to be applied to a sound synthesizer. In another embodiment, an adaptive function mapper (501) is trained to produce, in accordance with the information stored in a mapping store (503), synthesis parameters to be applied to a sound synthesizer, by steps including: analyzing sounds to produce sound parameters describing the sounds; further analyzing the sound parameters to produce control parameters; applying the control parameters to the adaptive function mapper (501), the adaptive function mapper (501) in response producing trial synthesis parameters comparable to the sound parameters; deriving from the sound parameters and the trail synthesis parameters an error measure in accordance with a perceptual error norm in which they are weighted in approximate degree to which they are perceived by the human ear; and adapting the information in the mapping store (503) with the error measure.

    摘要： In an electronic musical apparatus having an acoustic instrument manually operable to commence an acoustic vibration and a tone generator responsive to the acoustic vibration to generate a musical tone having a pitch corresponding to that of the acoustic vibration, a pitch detecting device utilizes a pickup (3) for picking up the acoustic vibration to convert the same into a waveform signal. Further, a first detector (13) operates according to a fast algorithm for processing the waveform signal so as to responsively produce a first output representative of the pitch of the acoustic vibration, and a second detector (12) operates in parallel to the first detector (13) for processing the same waveform signal according to a slow algorithm so as to stably produce a second output representative of the pitch of the acoustic vibration. A selector (17) selectively feeds one of the first output and the second output to the tone generator so that the first detector (13) and the second detector (12) can cooperate complementarily with each other to ensure responsive and stable detection of the pitch of the acoustic vibration. An additional detector (15) processes the waveform signal to measure a time interval between a pair of the peaks so as to detect a plucking point. A controller (21) controls the tone generator according to the detected plucking point to change the timbre of the tone generator in response to the plucking point.

    摘要： A method and apparatus for generating an audio notification file for a computing device are provided. A first audio file associated with a first mental state is selected as a first section of the audio notification file. The audio notification file enabled for storage in a memory. The audio notification file is further enabled for processing by a processing unit to control a speaker. A final state of the audio notification file is determined, the final state designated as a final section of the audio notification file, the final state associated with a second mental state. At least one intermediate section of the audio notification file is generated, between the first section and the second section, by morphing the first audio file to the final state by processing the first audio file using a digital signal processor.
