Embodiment Construction

[0058] Various exemplary embodiments, features, and aspects of the present disclosure will be described in detail below with reference to the accompanying drawings. The same reference numbers in the figures indicate functionally identical or similar elements. While various aspects of the embodiments are shown in drawings, the drawings are not necessarily drawn to scale unless specifically indicated.

[0059] In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be interpreted as indicating or implying relative importance or implicitly specifying the quantity of indicated technical features. Thus, a feature defined as "first" and "second" may explicitly or implicitly include one or more of these features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0060] The word "exemplary" is used exclusively herein to mean "serving as an example, embodiment, or illustration." ...

Abstract

The present application discloses an audio comparison method. The audio comparison method includes acquiring audio data of two channels, generating original buffer data from the audio data, generating slicing buffer data according to the original buffer data, and analyzing the audio data of the two channels. The slice buffer data is synchronized to obtain a first synchronization result, and the original buffer data of the two channels are synchronized according to the first synchronization result to obtain a second synchronization result. The original buffer data is converted into scribing buffer data for coarse synchronization search. On the basis of coarse synchronization, the search range can be greatly reduced, so that the calculation amount of the present disclosure can greatly save the calculation amount compared with the traditional algorithm.

Description

technical field [0001] The present disclosure relates to the technical field of audio processing, and in particular to an audio comparison method, device, and device. Background technique [0002] In video and audio applications, safety supervision and safe broadcast are becoming more and more important. In order to determine whether the video and audio data received by the receiving end has been tampered with on the transmission link, the same program can be transmitted to the receiving end through another independent transmission link, and then by comparing the video and audio data received by the two transmission links Audio data to determine whether the program content is consistent with the program source. Specifically for audio comparison, it is necessary to perform real-time comparison of all audio samples of all channels of the program to determine the consistency of their content. [0003] The same program, after being transmitted through two different links, is s...
