Assignee: ALIBABA GROUP HOLDING LIMITED
Field: Computer technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 12:
13. A device for processing audio data, comprising:
a memory for storing a set of instructions; and
at least one processor configured to execute the set of instructions to cause the device to perform:
acquiring audio data by an audio capturing device;
determining feature information of an enclosure in which the audio capturing device is located; and
reverberating the feature information into the audio data,

wherein reverberating the feature information into the audio data comprises:
testing a plurality of testing audio capturing devices within the plurality of testing enclosures to determine impulse response information of each testing audio capturing device caused by a corresponding testing enclosure;
generating a mapping relationship between feature information of the testing enclosures and the impulse response information of the testing audio capturing devices caused by the testing enclosures;
determining first impulse response information of the audio capturing device caused by the enclosure based on the feature information of the enclosure and the mapping relationship;
acquiring second impulse response information caused by background environment;
performing convolution process on the second impulse response information caused by the background environment and the audio data to generate an initially-processed audio data; and
performing convolution process on the first impulse response information of the audio capturing device caused by the enclosure and the initially processed audio data.
