Embodiment Construction

[0036] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0037] see figure 1 A method for processing audio data reverberation during live broadcast according to an embodiment of the present invention is provided, including: S1, recording original PCM audio data during live broadcast, and performing reverberation processing on the original PCM audio data; S2, reverberating The processed audio data is resampled, so that the length of the resampled audio data is consistent with the length of the original PCM audio data; S3, the resampled audio data is encoded and streamed.

[0038] In the process of audio and video live broadcast, in order to achieve different sound effects, audio reverberation processing is very common. The tradi...

Abstract

The present invention provides a reverberation processing method and system for audio data in a live broadcast process. The method includes: S1, recording original PCM audio data in the live broadcast process, and performing reverberation processing on the original PCM audio data; S2, performing reverberation processing on the original PCM audio data; The audio data after the reverberation processing is resampled, so that the length of the resampled audio data is consistent with the length of the original PCM audio data; S3, the resampled audio data is encoded and streamed. The present invention records and performs reverberation processing on the original audio data in the live broadcast process, and the length of the audio data after the reverberation processing is usually different from that of the original audio data, therefore, resampling the audio data after the reverberation processing, The length of the audio data after the reverberation processing is consistent with the length of the original audio data, and the synchronization problem of the audio and video after the reverberation processing is solved.

Description

technical field [0001] The present invention relates to the technical field of audio processing, and more specifically, to a reverberation processing method and system for audio data during live broadcasting. Background technique [0002] At present, in the process of live audio and video broadcasting, in order to enhance user experience, different sound effects can be added to the original audio, that is, audio reverberation can be realized. [0003] The traditional way to achieve audio reverberation is to directly record the original audio data and perform reverberation processing. Since the process of reverberation processing involves noise reduction power amplifier processing and data type conversion, etc., it will lead to The length of the audio data is inconsistent with the length of the original audio data, which causes the audio data after the reverberation processing to be out of sync with the original video data, which greatly affects the user experience.
