摘要： An audio processing system and method which calculates, based on spatial metadata of the audio object, a panning coefficient for each of the audio objects in relation to each of a plurality of predefined channel coverage zones. Converts the audio signal into submixes in relation to the predefined channel coverage zones based on the calculated panning coefficients and the audio objects. Each of the submixes indicating a sum of components of the plurality of the audio objects in relation to one of the predefined channel coverage zones. Generating a submix gain by applying an audio processing to each of the submix and controls an object gain applied to each of the audio objects. The object gain being as a function of the panning coefficients for each of the audio objects and the submix gains in relation to each of the predefined channel coverage zones.

摘要： Embodiments of identifying multimedia objects based on multimedia fingerprints are provided. Query fingerprints are derived from a multimedia object according to differing fingerprint algorithms. For each fingerprint algorithm, decisions are calculated through at least one classifier corresponding to the fingerprint algorithm based on the query fingerprint and reference fingerprints, the reference fingerprints being derived from reference multimedia objects according to the same fingerprint algorithm. Each of the decisions indicates a possibility that the query fingerprint and the reference fingerprint are not derived from the same multimedia content. For each of the reference multimedia objects, a distance is calculated as a weighted sum of the decisions relating to the reference fingerprints. The multimedia object is identified as matching the reference multimedia object with the smallest distance less than a threshold.
摘要翻译：提供了基于多媒体指纹识别多媒体对象的实施例。根据不同的指纹算法，从多媒体对象中导出查询指纹。对于每个指纹算法，通过基于查询指纹和参考指纹的至少一个与指纹算法相对应的分类器来计算决策，参考指纹根据相同的指纹算法从参考多媒体对象中导出。每个决定都指示查询指纹和参考指纹不是从相同的多媒体内容导出的。对于每个参考多媒体对象，将距离计算为与参考指纹相关的决定的加权和。多媒体对象被识别为具有小于阈值的最小距离的参考多媒体对象的匹配。
