Abstract

The invention relates to an audio data processing method and an audio data processing device. The method comprises the steps of acquiring adjacent first and second audio frames from an audio data stream, wherein the first audio frame is in prior to the second audio frame in time sequence; determining a frame segmentation position, wherein sampling point values at the frame segmentation positions in the first audio frame and the second audio frame meet a distance approximate condition; acquiring the sampling point value before the frame segmentation position in the second audio frame and the sampling point value after the frame segmentation position in the first audio frame, splicing the sampling point values in sequence to generate a third audio frame, and inserting the third audio frame between the first audio frame and the second audio frame. According to the audio data processing method and the audio data processing device provided by the invention, the noise generated when the audio frame is inserted can be substantially overcome.

Description

technical field [0001] The present invention relates to the technical field of audio data processing, in particular to an audio data processing method and device. Background technique [0002] The application of audio data processing technology enables people to collect sound through the pickup to generate audio data and store it. When needed, the stored audio data can be played out through the audio player to reproduce the sound. The wide application of audio data processing technology makes the recording and reproduction of sound very easy, which has an important impact on people's life and work. [0003] Currently, when processing an audio data stream, there is a situation where one frame of audio data needs to be inserted between two adjacent frames of audio data. For example, in some special sound effects, one frame of audio data is inserted between two adjacent frames of audio data streams of one of the left and right channels, so that the audio data streams of the le...
