Example Embodiment
[0041] Embodiment 1.
[0042] In this embodiment, description will be made from the perspective of an apparatus for determining audio similarity, which may specifically be integrated in a server or other equipment.
[0043] A method for determining audio similarity, comprising: acquiring first audio data and second audio data; respectively performing normalization processing and high-pass filtering on the first audio data and the second audio data to obtain the first audio data corresponding to the first audio data. First filtered data, second filtered data corresponding to the second audio data, and determining the short-term energy distribution of the first filtered data and the second filtered data respectively, to obtain first distribution information corresponding to the first filtered data , and second distribution information corresponding to the second filtered data; calculating the similarity between the first audio data and the second audio data based on the first di...
Example Embodiment
[0130] Embodiment two,
[0131] According to the methods implemented in the previous embodiments, the following examples will be used for further detailed description.
[0132] In this embodiment, the device for determining the audio similarity is specifically integrated in the server, the first audio file is an original audio file (ie, an original dubbing file), and the second audio file is a user audio file as an example for description.
[0133] like Figure 2a As shown, a method for determining audio similarity, the specific process can be as follows:
[0134] 201. The server acquires an original audio file, extracts first audio data from the original audio file, and acquires a user audio file, and extracts second audio data from the user audio file.
[0135]For example, after obtaining the original audio file, the server can transcode the original audio file according to a preset transcoding strategy, such as converting the original audio file into an uncompressed wav f...
Example Embodiment
[0207] Embodiment three,
[0208] In order to better implement the above method, an embodiment of the present invention further provides an apparatus for determining audio similarity, and the apparatus for determining audio similarity may specifically be integrated in a server or other equipment.
[0209] For example, as Figure 3a As shown, the apparatus for determining audio similarity may include an obtaining unit 301, a first processing unit 302, a second processing unit 303, and a calculating unit 304, as follows:
[0210] (1) Acquisition unit 301;
[0211] The acquiring unit 301 is configured to acquire first audio data and second audio data.
[0212] For example, the obtaining unit 301 can be specifically configured to obtain a first audio file, extract the first audio data from the first audio file, and obtain a second audio file, and extract the second audio data from the second audio file, and many more.
[0213] Optionally, in order to reduce interference, reduc...
