Problems solved by technology

[0005] 1. It is necessary to maintain the state machine of each audio stream, the control logic is complex, and the state switching process is often accompanied by resource application and release, which has a great impact on system performance;
[0006] 2. When the control strategy changes, the source code needs to be modified, the scalability is low, it cannot adapt to changes between different products, and the maintenance cost is high;
[0007] 3. It is not applicable to the processing of real-time audio streams, such as local radio stations, because such audio streams cannot be paused and require separate control logic
[0008] 4. The audio streams that need to be played cannot be played at the same time

Embodiment 1

[0071] Embodiment 1 of the present invention provides a multi-channel audio intelligent control method, the process of which is as follows figure 1 shown, including the following steps:

[0072] Step S101: Listening to audio focus changes.

[0073] Monitor whether the audio focus changes, and continue the follow-up process when the audio focus changes are detected.

[0074] Listening to audio focus changes can specifically refer to listening to audio streams acquiring or releasing audio focus, which may include at least the following two situations:

[0075] 1. When an audio stream is requested to be played and the conditions for enjoying the audio focus are met: the audio stream requested to be played is given the audio focus, and the audio stream that previously enjoyed the audio focus loses the audio focus.

[0076] 2. When the audio stream enjoying the audio focus finishes playing or requests to stop playing: stop playing the audio stream, release its audio focus, and an...

Embodiment 2

[0113] Embodiment 2 of the present invention provides a multi-channel audio intelligent control method, taking an audio stream request for playback as an example, the process is as follows figure 2 shown, including the following steps:

[0114] Assume that the preset volume rule is: when the audio stream has the audio focus, the playback volume is its original volume; when the audio stream does not have the audio focus, the playback volume is as shown in Table 1 above.

[0115] Step S201: Obtain the audio stream requested to be played.

[0116] Step S202: Determine the type of the audio stream.

[0117] Step S203: Determine the priority of the audio stream according to the type of the audio stream.

[0118] After the type of the audio stream is determined, its original volume and priority can be determined according to the preset matching relationship between the type of the audio stream and the original volume and priority.

[0119] Step S204: Determine whether the priori...

Embodiment 3

[0135] Embodiment 3 of the present invention provides a multi-channel audio intelligent control method. Taking an audio stream as an example when it is finished playing or requested to stop playing, the process is as follows image 3 shown, including the following steps:

[0136] The predetermined volume rule is as described in the second embodiment.

[0137] Step S301: Obtain an audio stream that has been played or is requested to stop playing.

[0138] If the audio stream is requested to stop playing, the audio stream will stop playing.

[0139] Step S302: Determine whether the audio stream has the audio focus when the audio stream is finished playing or requested to stop playing.

[0140] If yes, execute step S304; if no, execute step S303.

[0141] Step S303: continue to play the remaining audio streams according to the current playing state.

[0142] If it is judged that the audio stream does not enjoy the audio focus when the audio stream is played or requested to st...

Abstract

The invention discloses a multi-channel audio intelligent control method and a related device and equipment. The method comprises the following steps: when monitoring that an audio focus changes, adjusting the playing volume of each audio stream according to a preset volume rule. Different playing volumes are respectively adopted to play a plurality of audio streams at the same time, so that the problem caused by sound mixing can be well solved, simultaneous playing of a plurality of paths of audios can be realized, and auditory confusion cannot be caused. And the experience degree and the safety of a user are greatly improved.

Description

technical field [0001] The invention relates to the field of audio technology, in particular to a multi-channel audio intelligent control method and related devices and equipment. Background technique [0002] As we all know, in a system, at the same time, there may be multiple applications that need to use audio devices to output audio streams, which requires the system to have a "mixing" function, so that the human ear can hear the common sound of multiple channels at the same time. output. [0003] For example, for in-vehicle electronic equipment, when the vehicle is driving, navigation announcements, music playback, and telephone calls may sound at the same time, and the people in the car hear the effect of "mixed sound", which may cause auditory confusion. It may even lead to safety hazards. [0004] The traditional audio control solution is mainly for controlling the playback of audio streams, for example, during a call, the music is paused; when the call ends, the m...
