Detailed Description
In order that the above objects, features and advantages of the present invention can be more clearly understood, a more particular description of the invention will be rendered by reference to the appended drawings. It should be noted that the embodiments of the present invention and features of the embodiments may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited to the specific embodiments disclosed below.
The embodiment of the invention provides a method for detecting a microphone mute mode, which judges whether a microphone is a hardware blocking mute mode or not by detecting an audio stream of the microphone.
Specifically, as shown in fig. 1, the method for detecting the mute mode of the microphone includes the following steps:
detecting received audio data collected by an audio collection circuit on the microphone;
and if the audio stream is not detected, judging that the hardware blocks silence.
The method for detecting the mute mode of the microphone provided by the embodiment of the invention judges whether the microphone is blocked by hardware or not by detecting whether the audio stream in the audio data exists or not, thereby effectively solving the synchronization problem of hardware key event judgment. The method is easier and simpler, and can stably judge the hardware blocking event of the microphone.
In some possible embodiments, the received audio data captured by the audio capture circuit on the microphone is detected in real-time.
In the embodiment of the invention, the audio data collected by the audio collecting circuit on the microphone is transmitted to the detection software in real time, and the detection software also detects the received audio data collected by the audio collecting circuit on the microphone in real time so as to judge whether the microphone is a hardware blocking mute or not in real time.
In some possible embodiments, in the detecting of the audio data, the audio data when the hardware blocks the mute is set to 0;
reading the received audio data, reading one frame of audio data each time, and comparing the read audio data with 0;
and judging whether the microphone is a hardware blocking mute or not according to the comparison result.
After the microphone hardware blocks silence, audio data collected by an audio collecting circuit of the microphone has no audio stream and no environmental noise; under the condition that the microphone is not blocked by hardware, the audio data collected by the audio collecting circuit of the microphone can be normally captured into the audio stream, and even if the surrounding environment is quite quiet, the audio data such as noise in the environment can be normally captured.
Therefore, in the detection program, the audio data when the hardware blocks the mute is set to be 0, and then the detected audio data is compared with 0, if the detected audio data is not 0, the microphone is not the hardware blocks the mute; if the detected audio data is 0, the microphone is indicated to be hardware-blocking mute.
In some possible embodiments, if the audio data in 2 frames or more are all different from 0, the hardware blocking mute is determined.
In different embodiments, if 2 frames of continuous audio data are different from 0, it is determined that the hardware blocks silence; or if 3 frames of continuous audio data are different from 0, judging that the hardware blocks silence; or if 5 frames of continuous audio data are different from 0, judging that the hardware blocks silence; or judging that the hardware blocks silence when 6 continuous frames of audio data are different from 0; or judging that the hardware blocks silence when 8 continuous frames of audio data are different from 0; and so on. In actual detection, in order to obtain a detection result in time, generally, audio data in 2-5 frames are different from 0, and it is determined that the hardware is blocked and muted.
For example, n frames of data are continuously read from a segment of audio data, each time one frame of data is read, the n frames of data are compared with 0, and if the n-5 frames of continuously compared data are all 0, it can be determined that the microphone is muted by hardware block; otherwise, if there is a data frame other than 0 in the continuous frames with n being 5, the microphone is considered to have been muted by the hardware block at this time. The detected audio stream is shown in fig. 2.
As shown in fig. 3, there is also provided a system for detecting a mute mode of a microphone according to an embodiment of the present invention, including:
the receiving module is used for receiving audio data collected by an audio collecting circuit on the microphone;
the detection module is used for detecting whether the audio data of the receiving module has an audio stream or not;
and the output module is used for outputting whether the microphone is a hardware blocking mute or not according to the result of the detection module.
In the system for detecting the mute mode of the microphone provided by the embodiment of the invention, the receiving module is used for receiving the audio data of the microphone; the detection module is used for detecting whether the received audio data has audio streams; the output module judges whether the microphone is blocked by hardware or not by using the existence of the audio stream in the detected audio data, and the synchronization problem of hardware key event judgment is effectively solved. The method is easier and simpler, and can stably judge the hardware blocking event of the microphone.
In some possible embodiments, the detection module detects the audio data of the receiving module in real time.
In the embodiment of the invention, the audio data collected by the audio collecting circuit on the microphone is transmitted to the detection software in real time, and the detection software also detects the received audio data collected by the audio collecting circuit on the microphone in real time so as to judge whether the microphone is a hardware blocking mute or not in real time.

the reading unit is used for reading the received audio data and reading one frame of audio data each time;
the comparison unit is used for comparing the read audio data with 0;
and the judging unit is used for judging whether the microphone is a hardware blocking mute or not according to the comparison result.
After the microphone hardware blocks silence, audio data collected by an audio collecting circuit of the microphone has no audio stream and no environmental noise; under the condition that the microphone is not blocked by hardware, the audio data collected by the audio collecting circuit of the microphone can be normally captured into the audio stream, and even if the surrounding environment is quite quiet, the audio data such as noise in the environment can be normally captured.
Therefore, in the detection module, different units are provided to process the detected items, respectively. If the setting unit is used, the audio data when the hardware blocks the mute is set to be 0; the reading unit reads the received audio data and reads one frame of audio data each time; a comparing unit comparing with 0 according to the detected audio data; the judging unit judges whether the microphone is hardware blocking mute or not according to the comparison result, and if the detected audio data contains data which is not 0, the microphone is not hardware blocking mute; and if the detected audio data are all 0, the microphone is indicated to be mute by hardware blocking.
In some possible embodiments, if the audio data in 2 frames or more are all different from 0, the hardware blocking mute is determined.
In different embodiments, if 2 frames of continuous audio data are different from 0, it is determined that the hardware blocks silence; or if 3 frames of continuous audio data are different from 0, judging that the hardware blocks silence; or if 5 frames of continuous audio data are different from 0, judging that the hardware blocks silence; or judging that the hardware blocks silence when 6 continuous frames of audio data are different from 0; or judging that the hardware blocks silence when 8 continuous frames of audio data are different from 0; and so on. In actual detection, in order to obtain a detection result in time, generally, audio data in 2-5 frames are different from 0, and it is determined that the hardware is blocked and muted.
