摘要： Fingerprints are bit strings extracted from a media signal (e.g. an audio or video clip) to identify said media signal. Typically, they are derived from a perceptual property of the signal, for example, the spectral energy distribution of an audio fragment or the luminance distribution of a video image. A method and arrangement for extracting a fingerprint is here disclosed which is robust with respect to shifts of the perceptual property. Such shifts occur, inter alia, when the fingerprint is derived from a logarithmically mapped spectral energy distribution of an audio signal and said audio signal is subjected to speed changes. According to the invention, the fingerprint is not derived from the perceptual property as such, but from its auto-correlation function.

摘要： A method of deriving information from an audio track, or a part thereof, wherein onsets or intensity/amplitude variations are detected as well as at which frequencies (timbral frequencies) or in which frequency bands these occur. Especially interesting is the frequency of such onsets. In this manner, the frequency of beats of a low frequency drum may be separated from that of onsets of a higher frequency drum or guitar of other instrument, and these frequencies provide important information about the track, such as genre, beat, etc. Naturally, parameters may be provided relating to the individual frequencies (frequency of onsets and frequency/tone of the sound of the onsets), or a fit thereto may be used to reduce the number of parameters. It is noted that the frequencies in which the onsets are determined may be tones or half tones in the relevant scale. As onsets of instruments normally are whole multiples of a basic frequency or beat, it has been found advantageous to represent the individual frequencies on a logarithmic scale so that such multiples of frequencies are equidistant and so that transposing to higher or lower beats is very easy.
摘要翻译：从音频轨道或其一部分导出信息的方法，其中检测到发射或强度/幅度变化，以及哪些频率（频率频率）或哪些频带发生。特别有趣的是这种onsets的频率。以这种方式，低频鼓的节奏频率可以与其他乐器的较高频率鼓或吉他的开头的频率分开，并且这些频率提供关于轨道的重要信息，例如类型，节拍等。自然地可以提供与各个频率（开启的频率和开启的声音的频率/音调）相关的参数，或者可以使用与其相配合来减少参数的数量。注意，确定开始的频率可以是相关尺度中的音调或半音。由于仪器的通常通常是基本频率或节拍的整数倍，已经发现有利的是以对数标度表示各个频率，使得频率的这种倍数是等距的，因此转置到更高或更低的节拍是非常容易的。

摘要： The present invention contains three methods for quickly deducing the fundamental frequency of a complex wave form or signal. One method uses the relationships between and among the frequencies of higher harmonics including ratios of frequencies, differences between frequencies, ratios of frequency differences, and relationships stemming from the fact that harmonic frequencies are modeled by functions of an integer variable whose values represent harmonic ranking numbers. Another method depicts the predicted/modeled relationships of the harmonics of selected frequency registers on logarithmic scales, records the frequencies of detected partials on like scales, and moves the scales with respect to each other searching for a match of three harmonics. When such a match is found, possible harmonic ranking numbers and the implied fundamental frequency can be extracted directly. When the detected partials match more that one set of predicted/modeled harmonic relationships, algorithms of the first method are used to select the deduced fundamental. By still another method, harmonic frequencies for a plurality of fundamentals are amassed and organized so that partials linked to an unknown fundamental can be compared with them and the unknown fundamental deduced.

摘要： A method of manipulating a complex waveform by considering the harmonic and partial frequencies as moving targets over time in both amplitude and frequency and adjusting the moving targets by moving modifiers in both amplitude and frequency. The manipulation of harmonic frequencies and the synthesis of harmonic frequencies are based on the harmonic rank. The modifiers move with the movement of the frequencies based on rank. Harmonic transformation modifies, by rank, the waveform from one source to a waveform of a second or target source. Harmonics and other partials accentuation identifies each of the frequencies and its relationship to adjacent frequencies as well as fixed or moving thresholds and make the appropriate adjustment. Interpolation is also disclosed as well as models which imitate natural harmonics.

摘要： A digital sampling instrument having the features of non-redundant data loading, single-cycle-fetch-and-store memory operations, and volume scaling. Sound data stored in a floppy disk (26) is assigned to a unique number associated with a sound stored in a sound RAM (60) to determine if loading the sound from the floppy disk (26) would be redundant. An address generator circuit located within an address generator/data decoder circuit (50) includes pipeline architecture to enable both a fetch and store operation to be performed in a single memory clock cycle. Volume scaling is achieved by storing both sound data and volume data in logarithmic form, adding the two, and converting to a linear format.

摘要： A musical instrument and a method which retunes and adjusts volumes in response to the chord being sustained and the way that chord is voiced. The instrument is capable of producing tones, the intervals between which are equal tempered intervals of a twelve note octave, and tones, the intervals between at least some of which are determined by identifying at least selected ones of the notes the instrument is being commanded to produce. The method includes identifying the at least selected ones of the notes the instrument is being commanded to produce, providing a map for mapping the identified notes to a chord type, identifying a note in that chord type, and substituting a frequency closer to a harmonic of the identified note for the frequency of at least one harmonic of at least one other note the instrument is being commanded to produce.
