Embodiment Construction

[0021] Below, the present invention will be further described in conjunction with the accompanying drawings and specific embodiments.

[0022] Such as figure 1 Shown, a kind of 2-way audio mixing method comprises the steps:

[0023] Step 1: Receive 2 channels of audio data, and store the 2 channels of audio data into the same two-dimensional array to obtain the two-dimensional array audio data.

[0024] The 2 channels of audio data are 2 channels of audio stream data to be mixed, for example, one channel is network audio stream data, and the other channel is local audio stream data.

[0025] Assuming that the network audio stream data is networkAudio, the local audio stream data is nativeAudio, and the obtained two-dimensional array audio data is bMulRoadAudioes, then in the program, store the two channels of audio data into the same two-dimensional array as follows:

[0026] Byte[][]bMulRoadAudioes={byte[]nativeAudio,byte[]networkAudio}.

[0027] Step 2: Determine whether ...

Abstract

The invention discloses a two-way audio mixing method and a processing terminal, and the method comprises the steps: receiving two-way audio data, and storing the two-way audio data in the same two-dimensional array to obtain two-dimensional array audio data; judging whether the two-dimensional array audio data meets a condition I, if so, continuing processing, and if not, ending processing; converting all data elements in the two-dimensional array audio data into hexadecimal data, and shifting the data element where the singular pointer address is located left by 8 bits to obtain converted array audio data; traversing all data elements in the audio data of the conversion array, accumulating and summing all the data elements, and dividing by 2 to obtain mixed audio data; and recovering all data elements of the mixed audio data to be binary, shifting the data element where the singular pointer address is located rightwards by 8 bits, storing the obtained array audio data in the empty audio file, and obtaining a complete audio data file. According to the invention, the audio quality can be ensured while audio interaction is realized, and the data processing amount is small.

Description

technical field [0001] The invention relates to the technical field of audio mixing, in particular to a 2-way audio mixing method and a processing terminal. Background technique [0002] In video calls or other scenarios, the process needs to process the network audio data transmitted from the remote end and the local audio data through a mixing algorithm before outputting, so as to improve the sound mixing quality. Many existing audio mixing algorithms are complicated to process, process a large amount of data, and consume a large amount of computing resources, so they are not suitable for devices with relatively limited computing resources such as mobile terminals. Therefore, an algorithm with a small amount of data processing and good sound mixing effect is needed. Contents of the invention [0003] In view of the deficiencies in the prior art, one of the purposes of the present invention provides a 2-way audio mixing method, which can solve the problems of large audio...
