摘要： In accordance with the present invention, a method and apparatus are provided wherein loop discontinuities are eliminated. In the case of amplitude discontinuities, the harmonic amplitudes contained in the loop are progressively scaled over the duration of the loop, so that for each harmonic the loop end amplitude matches the loop beginning amplitude. In the case of phase discontinuities, the harmonic phases are progressively shifted over the duration of the loop, so that for each harmonic the loop end phase matches the loop beginning phase. Shifting the phase is accomplished by slightly altering the frequency of the harmonics to produce the desired amount of phase-shift at the loop end. In accordance with the present invention, the method also provides a technique to select loop begin and end points to minimize the amount of phase adjustment.
摘要翻译：根据本发明，提供了一种消除循环不连续性的方法和装置。在幅度不连续的情况下，循环中包含的谐波振幅在循环的持续时间内逐渐缩放，因此对于每个谐波，环路端振幅与环路起始幅度相匹配。在相位不连续的情况下，谐波相位在环路的持续时间内逐渐移动，因此对于每个谐波，环路端相位与环路开始相位匹配。通过稍微改变谐波的频率以在环路端产生期望量的相移来实现转换相位。根据本发明，该方法还提供一种选择循环开始和结束点以最小化相位调整量的技术。

摘要： The apparatus is a turntable assembly which includes a rotary turntable platter, a phonographic cartridge, and a tonearm for impinging the phonographic cartridge against a record on the rotary turntable platter. The record includes MIDI timing signals encoded therein. The apparatus further includes an amplifier, an analog-to-digital converter and a signal processing means for amplifying the resulting phonographic signal, converting the phonographic signal into digital format and extracting the timing signal so as to generate an output MIDI timing code for controlling the playback of an external audio signal.

摘要： A method and apparatus for processing data representing a time history of a sonic waveform. A portion of the data is processed to determine a beat frequency by performing a transformation from the time domain to the frequency domain and, based on the energy of the frequencies of the sonic waveform, produce an energy vector for each frequency band. The data is also processed to detect and order transients found in the sonic waveform and use these transients to establish the tempo of the sonic waveform.

摘要： A music piece distributing apparatus receives a request signal including music piece identification information and compressing system identification information from a receiving apparatus and transmits music piece data in which a music piece corresponding to the music piece identification information has been compressed by a compressing system corresponding to the compressing system identification information to the receiving apparatus. The request signal is transmitted through a public line. A music piece receiving apparatus receives the music piece data from the music piece distributing apparatus by a digital broadcasting receiving apparatus and decodes the received music piece data by a compression decoding system corresponding to the compressing system designated by the compressing system identification information.

摘要： An automatic performance apparatus is constituted by a memory section, a performance section, and a control section. The memory section stores music sequence data used for carrying out an automatic performance of a music piece, and condition setting data used for setting a condition of the automatic performance. The performance section reads out the condition setting data from the memory section to set the condition of the automatic performance, and reads out the music sequence data from the memory section to carry out the automatic performance under the set condition. The control section controls a first rate of reading of the condition setting data faster than a second rate of reading of the music sequence data, thereby accelerating the setting of the condition prior to the automatic performance.

摘要： Systems and methods for extracting a music snippet from a music stream are described. In one aspect, the music stream is divided into multiple frames of fixed length. The most-salient frame of the multiple frames is then identified. One or more music sentences are then extracted from the music stream as a function of peaks and valleys of acoustic energy across sequential music stream portions. The music snippet is the sentence that includes the most-salient frame.

摘要： When adjoining, i.e. Preceding and succeeding, waveform-forming module data are to be interlined, a mutual approaching rate is designated, and the preceding and succeeding module data are modified in accordance with the designated mutual approaching rate. The modification based on the mutual approaching rate allows the preceding and succeeding module data to approach each other and thus provides for smooth link or connection between the two module data. Further, by designating a link starting point in the preceding module data and/or a link ending point in the succeeding module data, the preceding and succeeding module data are interlined to an appropriate degree depending on a difference or degree of similarity between the two module data. If the preceding or succeeding module data include data of a plurality of vectors, a time relationship between the preceding and succeeding module data is evaluated, and the data of one or more of the vectors is thinned out, as necessary, in accordance with the evaluated time relationship so that the two module data can be interlined appropriately.
