    摘要： A method is performed of selecting a signal of interest from a compound signal. The method includes generating a matrix and initializing a first row of the matrix to zero. The compound signal is obtained as a digital waveform signal, with sampling rate S samples per second. For each sample of the digital signal, a new entry is recursively computed for the matrix. For each frequency bin in the matrix (where f is the center frequency of the bin) the value in the new row is computed by multiplying the value for that bin in the previous row by the complex number r*ei2πf/S and adding the new signal sample multiplied by a real constant. The method includes identifying the signal of interest from the matrix, whereby an uncertainty of which frequency bin the signal of interest exists in is eliminated.

    摘要： System, apparatus and method for determining semantic information from audio, where incoming audio is sampled and processed to extract audio features, including temporal, spectral, harmonic and rhythmic features. The extracted audio features are compared to stored audio templates that include ranges and/or values for certain features and are tagged for specific ranges and/or values. The semantic information may be associated with audio signature dataExtracted audio features that are most similar to one or more templates from the comparison are identified according to the tagged information. The tags are used to determine the semantic audio data that includes genre, instrumentation, style, acoustical dynamics, and emotive descriptor for the audio signal.

    摘要： During operation, a “coarse search” stage applies variable-scale windowing on the query pitch contours to compare them with fixed-length segments of target pitch contours to find matching candidates while efficiently scanning over variable tempo differences and target locations. Because the target segments are of fixed-length, this has the effect of drastically reducing the storage space required in a prior-art method. Furthermore, by breaking the query contours into parts, rhythmic inconsistencies can be more flexibly handled. Normalization is also applied to the contours to allow comparisons independent of differences in musical key. In a “fine search” stage, a “segmental” dynamic time warping (DTW) method is applied that calculates a more accurate similarity score between the query and each candidate target with more explicit consideration toward rhythmic inconsistencies.

    摘要翻译： 在操作期间，“粗略搜索”阶段在查询音调轮廓上应用可变尺度窗口，以将其与目标俯仰轮廓的固定长度段进行比较，以在有效扫描可变速度差异和目标位置的同时找到匹配候选。 因为目标段是固定长度的，所以这具有显着减少现有方法所需的存储空间的效果。 此外，通过将查询轮廓分解成部分，可以更灵活地处理节奏不一致。 归一化也适用于轮廓，以便独立于音乐键的差异进行比较。 在“精细搜索”阶段，应用“分段”动态时间扭曲（DTW）方法，通过更明确地考虑节奏不一致来计算查询和每个候选目标之间的更准确的相似性分数。

    摘要： A technique is disclosed for evaluating an audio characteristic such as singing ability, and processing an image to be displayed according to the evaluation result in a manner that can attract the interest of a user. JPEG 2000 code data of a moving image for a karaoke system, for example, are transmitted from a server to a client along with accompanying audio data, and the code data are then decoded at a decoder to form an image to be displayed. An audio signal such as the voice of the user that is input to a microphone is evaluated at an evaluation unit, and the evaluation result is transmitted to the server. Based on this evaluation result, an inter-code transform unit conducts image processing by selectively discarding codes from code data of an image that are to be transmitted to the client.

    摘要： An additive sound synthesis process for generating complex, realistic sounds is realized in a computationally efficient manner. In accordance with one aspect of the invention, polyphony is efficiently achieved by dosing the energy of a given partial between separate transform sums corresponding to different channels. In accordance with another aspect of the invention, noise is injected by randomly perturbing the phase of the sound, either on a per-partial basis or on a transform-sum basis. In the latter instance, the phase is perturbed in different regions of the spectrum to a degree determined by the amount of energy present in the respective regions of the spectrum. In accordance with yet another aspect of the invention, a transform sum representing a sound is processed in the transform domain to achieve with great economy effects achievable only at much greater expense outside the transform domain. Other transforms besides the Fourier transform may be used to advantage. For example, use of the Hartley transform produces comparable results but allows transforms to be computed at approximately twice the speed as the Fourier transform.
