Detailed Description
In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
Electronic devices (such as smart phones and tablet computers) have become one of the most common consumer electronic products in daily life, and with the development of wireless communication technology, wireless headsets are increasingly widely used due to the characteristics of convenience in carrying and the like when users record sounds by using the electronic devices. Among them, a True Wireless Stereo (TWS) headset has an increasing share in the headset market due to its excellent characteristics of being more comfortable to wear, convenient to use, unobtrusive, smaller and more beautiful.
Binaural stereo recording (Binaural Audio) is a recording technique that highly restores the real sense of hearing by providing microphones at the positions of both ears of an artificial head so that sound arriving at the position of each ear can be captured and both signals can be reproduced separately at each ear. This reproduction is not suitable for monophonic playback, and if the desired effect is not achieved by speaker playback, headphones are often used to completely separate the sound signals received by the two ears, which allows the artificial head to completely reproduce the content heard by the listener.
When the binaural stereo recording is realized, microphones (microphones, MIC) respectively arranged on two earphones of the TWS earphone can be used for receiving sound, and the effect of the binaural recording technology can be achieved. After two earphones of the TWS earphone collect audio data, the recorded dual-channel audio needs to be transmitted to the mobile phone Bluetooth through a Bluetooth protocol. Because the recording sound field needs to be guaranteed, the format of the recorded audio needs to guarantee at least 48khz, 16bit and 2 sound channels, and the bandwidth after compression also needs at least 400 and 500kbps (kilobits per second), if the signal of bluetooth fluctuates or the earphone is far away from the mobile phone, the transmission bandwidth will become small, and the transmission process is easy to be jammed or interrupted, thereby causing the recording to be jammed or interrupted.
In view of the above problems, the inventor provides a coding control method, an apparatus, a wireless headset and a storage medium provided in this embodiment of the present application, which can be used to transmit audio data to a first wireless headset of an electronic device during recording by the first wireless headset and a second wireless headset, and control code rates of the first wireless headset and the second wireless headset for coding the audio data according to communication quality parameters of wireless communication between the first wireless headset and the electronic device, so as to avoid the jamming or interruption of the recorded audio due to the jamming during audio data transmission, thereby improving the recording effect.
Before introducing the coding control method of the embodiment of the present application, an application environment corresponding to the coding control method is introduced. As shown in fig. 1, an application environment corresponding to the encoding control method includes a sound recording system 10, where the sound recording system 10 includes an electronic device 11, a first wireless headset 12, and a second wireless headset 13. The electronic device 11 may be a smart phone, a tablet computer, an electronic book, a smart wearable device, or the like, which is capable of running an application program and has a function of collecting an audio signal. The first Wireless earphone 12 and the second Wireless earphone 13 form a True Wireless Stereo (TWS) earphone, wherein the left and right earphones of the TWS earphone are independent from each other and do not need to be connected by cables, and Wireless separation of left and right sound channels can be realized. In the embodiment of the present application, the sounds of the left and right channels can be collected by the first wireless earphone 12 and the second wireless earphone 13, respectively.
In the embodiment of the present application, an application program capable of acquiring audio is installed in the electronic device 11, and specifically, the application program may be audio playing software, video playing software, or call software, or other software capable of triggering audio playing. An audio acquisition device, such as a microphone, may be disposed in each of the first wireless headset 12 and the second wireless headset 13. The first wireless headset 12 and the second wireless headset 13 may be provided with an audio capturing device to capture audio signals, and the electronic device 11 may process the audio signals to generate audio files. Of course, the electronic device 11 may also send the audio to be played to at least one of the first wireless headset 12 and the second wireless headset 13, and play the voice by at least one of the first wireless headset 12 and the second wireless headset 13.
As an embodiment, as shown in fig. 2, the electronic device 11 can be connected to the first wireless headset 12 and the second wireless headset 13 at the same time. The first wireless headset 12 and the second wireless headset 13 can directly transmit audio data to the electronic device 11, or receive and play audio data transmitted by the electronic device 11.
As another embodiment, as shown in fig. 3, the electronic device 11 is connected to the first wireless headset 12 through bluetooth, and then the first wireless headset 12 is connected to the second wireless headset 13 through bluetooth, so that the electronic device 11, the first wireless headset 12 and the second wireless headset 13 are connected simultaneously through networking, that is, the first wireless headset 12 serves as a relay for the electronic device 11 and the second wireless headset 13.
In the embodiment of the present application, the electronic device 11, the first wireless headset 12 and the second wireless headset 13 are connected in the manner shown in fig. 3, so that the first wireless headset 12 can be used as a master headset, and the second wireless headset 13 can be used as a slave headset.
Referring to fig. 4, fig. 4 is a flowchart illustrating a coding control method according to an embodiment of the present application. In a specific embodiment, the encoding method may be applied to the above-mentioned sound recording system, and specifically, the execution subject of the method may be a first wireless earphone, the first wireless earphone and the second wireless earphone are both provided with audio acquisition devices, and the first wireless earphone and the second wireless earphone adopt the connection manner shown in fig. 4. As will be described in detail with respect to the flow shown in fig. 4, the encoding control method may specifically include the following steps:
step S110: in the process of audio acquisition of the first wireless earphone and the second wireless earphone, the first wireless earphone sends the audio data acquired by the first wireless earphone and the second wireless earphone respectively and coded to the electronic equipment.
The first wireless earphone is used as a main earphone and is connected with the electronic equipment and the second wireless earphone, and when the first wireless earphone and the second wireless earphone are used for recording, the first wireless earphone and the second wireless earphone can respectively collect audio data and encode the collected audio data to obtain the audio data for being transmitted to the electronic equipment. The first wireless earphone encodes the collected audio data to obtain audio data which can be used as audio data corresponding to one of the two channels; the second wireless earphone encodes the collected audio data to obtain audio data, and the audio data can be used as audio data corresponding to another channel in the two channels. Optionally, the audio data collected and encoded by the first wireless headset may be audio data corresponding to a left channel, and the audio data collected and encoded by the second wireless headset may be audio data corresponding to a right channel; alternatively, the audio data collected and encoded by the first wireless headset may be the audio data corresponding to the right channel, and the audio data collected and encoded by the second wireless headset may be the audio data corresponding to the left channel.
In this embodiment of the application, when recording is performed through the first wireless earphone and the second wireless earphone, in a process of acquiring audio data through the first wireless earphone and the second wireless earphone, and when the first wireless earphone is a main earphone connected to the electronic device, the audio data acquired and encoded by the first wireless earphone and the audio data acquired and encoded by the second wireless earphone may be sent to the electronic device through the first wireless earphone. When the first wireless earphone collects and codes audio data to obtain audio data of one of the two channels, the second wireless earphone also collects and codes the audio data to obtain audio data of the other of the two channels, and the second wireless earphone is connected with the first wireless earphone to send the obtained audio data to the first wireless earphone; the first wireless earphone can combine the audio data of the two sound channels and then send the combined audio data to the electronic equipment, so that the electronic equipment can receive the audio data of the two sound channels acquired by the first wireless earphone and the second wireless earphone and generate an audio file according to the received audio data.
In some embodiments, when the first wireless headset and the second wireless headset are used in a recording process, the first wireless headset and the second wireless headset may be in a wearing state or a non-wearing state. For example, the first wireless headset and the second wireless headset may be worn by the same user in the left ear and the right ear, so that sound arriving at each ear position can be captured and recorded audio can be reproduced separately in each ear when played; for another example, the first wireless earphone and the second wireless earphone can be worn by different users in the same real scene, so that audio data at different spatial positions in the space where the real scene is located can be acquired, and a spatial sense can be reproduced when the recorded audio is played; for another example, the first wireless headset may be worn and the second wireless headset may be held in the hand, thereby enabling recording in an interview scenario. Of course, the wearing states of the first wireless earphone and the second wireless earphone for recording may not be limited.
In some embodiments, the first wireless headset and the second wireless headset may also be used to capture the sound of a given user when used for recording. Optionally, the first wireless headset and the second wireless headset may collect the sound of the designated user according to a phase angle between the sound source and the second wireless headset, or according to a voiceprint feature of the designated user, so as to obtain the audio data of the designated user. When the first wireless earphone and the second wireless earphone are used for collecting the sound of a designated user, the first wireless earphone and the second wireless earphone can collect the sound of the same user, for example, the teaching audio of a teacher is collected in a teaching scene; the first wireless headset and the second wireless headset may also be used by the user to capture different user sounds, for example, in an interview scenario, the first wireless headset may be used to capture the interviewer's sound and the second wireless headset may be used for the interviewee's sound. Of course, the specific application scenario of the first wireless headset and the second wireless headset for recording may not be limited.
In some embodiments, when the first wireless headset transmits the encoded audio data collected by the first wireless headset and the encoded audio data collected by the second wireless headset to the electronic device, the encoded audio data collected by the first wireless headset and the encoded audio data collected by the second wireless headset may be combined into an audio data packet.
In a possible implementation manner, the audio data collected by the first wireless headset and the audio data collected by the second wireless headset respectively and subjected to encoding include timestamps, and the first wireless headset may combine the audio data with the same timestamp in the audio data acquired by the first wireless headset and the audio data acquired by the second wireless headset respectively according to the timestamps included in the audio data to obtain an audio data packet for sending to the electronic device.
In a possible implementation manner, the first wireless earphone and the second wireless earphone may generate audio data packets according to audio data generated within the same duration in the audio acquisition process, when recording starts, the first packet of audio data packets may be synchronized, after the synchronization succeeds, the audio data packets generated by the first wireless earphone and the second wireless earphone are combined, and the subsequent generated audio data packets do not need to be synchronized and may be directly combined to obtain the audio data packets for sending to the electronic device.
Step S120: and acquiring communication quality parameters of wireless communication between the first wireless earphone and the electronic equipment.
In the embodiment of the application, the first wireless earphone can acquire the communication quality parameter of the wireless communication between the first wireless earphone and the electronic device in the recording process, so that the communication quality of the wireless communication between the first wireless earphone and the electronic device can be determined according to the communication quality parameter, and the coding code rate of the first wireless earphone and the coding code rate of the second wireless earphone for coding the acquired audio data are dynamically controlled, so that the bandwidths required by the first wireless earphone when the audio data are transmitted to the electronic device are different, and the blockage during the transmission is avoided.
In some embodiments, the first wireless headset may detect, in real time, a communication quality parameter of wireless communication between the first wireless headset and the electronic device, so as to control, according to the communication quality parameter, an encoding rate at which the first wireless headset and the second wireless headset encode the collected audio data, so that the encoding rate matches the communication quality; the first wireless headset may also acquire the communication quality parameter of the wireless communication between the first wireless headset and the electronic device according to the set frequency, for example, the first wireless headset may acquire the communication quality parameter of the wireless communication between the first wireless headset and the electronic device every 10 seconds.
In some embodiments, the communication quality parameters may include one or more of the following parameters: received signal strength, retransmission rate, packet loss rate, and channel occupancy. It is to be understood that the obtained communication quality parameter may reflect the communication quality of the wireless communication between the first wireless headset and the electronic device, and of course, the specific communication quality parameter may not be limited, for example, the communication quality parameter may also include a magnitude vector difference, and the like.
Alternatively, the communication quality parameter may include a bluetooth received signal strength. When the first wireless headset acquires the bluetooth receiving signal strength, the first wireless headset may determine the first receiving signal strength according to a broadcast sent by the electronic device, acquire a second receiving signal strength detected by the electronic device from the electronic device, and calculate a third receiving signal strength according to the first receiving signal strength and the second receiving signal strength, as the bluetooth receiving signal strength between the first wireless headset and the electronic device. For example, an average value of the first received signal strength and the second received signal strength may be acquired as the third received signal strength, and the third received signal strength may be obtained by performing a weighted calculation on the first received signal strength and the second received signal strength based on a weight corresponding to the first received signal strength and a weight corresponding to the second received signal strength, for example. In addition, when the first and second received signal strengths are obtained, a plurality of received signal strengths measured within a certain period of time may be obtained, and an average value may be obtained based on the plurality of received signal strengths to obtain the first and second received signal strengths, for example, the first wireless headset may detect 8192 times within 1 second and calculate the average value to obtain the first received signal strength.
Optionally, the communication quality parameter may include a retransmission rate. When the first wireless headset acquires the retransmission rate, the first wireless headset may acquire a ratio between the number of automatic retransmissions and the preset number after sending the preset number of data packets to the electronic device, so as to obtain the retransmission rate. When the first wireless headset acquires the retransmission rate, the first wireless headset may also acquire the number of data packets sent in the target duration as a first number, and the number of automatically retransmitted data packets as a second number, and then acquire a ratio of the second number to the first number to obtain the retransmission rate.
Step S130: and respectively controlling the coding rates of the first wireless earphone and the second wireless earphone for coding the collected audio data according to the communication quality parameters.
In this embodiment of the application, after the first wireless headset acquires the communication quality parameter, the first wireless headset and the second wireless headset may respectively control, according to the communication quality parameter, an encoding rate at which the collected audio data is encoded by the first wireless headset and the second wireless headset, so that the encoding rate is matched with the communication quality parameter, and the situation that the audio data is jammed when being transmitted to the electronic device due to a high encoding rate when the communication quality is poor is avoided.
In some embodiments, when the first wireless headset controls the first wireless headset and the second wireless headset to encode the encoding rate of the collected audio data according to the communication quality parameter, the encoding rate matching the communication quality parameter may be determined, and then the first wireless headset is controlled to encode at the encoding rate; in addition, the determined coding rate can be sent to the second wireless headset to instruct the second wireless headset to perform coding at the coding rate, so that the coding rates of the first wireless headset and the second wireless headset can be respectively controlled according to the communication quality parameters.
In some embodiments, the first wireless headset may control the first wireless headset to perform encoding at the encoding code rate after determining the corresponding encoding code rate according to the communication quality parameter; in addition, the communication quality parameter may be sent to the second wireless headset, and the second wireless headset determines a corresponding coding rate according to the communication quality parameter in the same manner of determining the coding rate, and then controls the second wireless headset to perform coding at the coding rate.
According to the coding control method provided by the embodiment of the application, in the process of audio acquisition of the first wireless earphone and the second wireless earphone, the first wireless earphone is used for transmitting audio data to the electronic equipment, and according to the communication quality parameters of wireless communication between the first wireless earphone and the electronic equipment, the code rates of the first wireless earphone and the second wireless earphone for coding the audio data are controlled, so that the coding code rates are adaptive to the communication quality parameters, the blocking and pause of the audio data during transmission are avoided, the blocking and pause of the recorded audio are caused, and the recording effect is improved.
Referring to fig. 5, fig. 5 is a flowchart illustrating a coding control method according to another embodiment of the present application, where the coding control method is applied to the first wireless headset. In this embodiment, the communication quality parameters acquired by the first wireless headset may include a plurality of quality parameters. As will be described in detail with respect to the flow shown in fig. 5, the encoding control method may specifically include the following steps:

Step S230: and determining the corresponding coding code rate as a target code rate according to the multiple quality parameters.
In this embodiment of the application, the communication quality parameters of the wireless communication with the electronic device, which are acquired by the first wireless earphone, may include multiple quality parameters, so as to synthesize the multiple quality parameters and determine the coding rate corresponding to the first wireless earphone and the second wireless earphone as the target coding rate. The plurality of quality parameters may include at least received signal strength, retransmission rate, and packet loss rate, and of course, the plurality of quality parameters may also include more parameters for reflecting communication quality between the first wireless headset and the electronic device, for example, parameters such as channel occupancy ratio may also be included.
In some embodiments, a correspondence between the coding rate and different parameter values of the multiple quality parameters may be preset, and the first wireless headset may obtain, as the target coding rate, the coding rate corresponding to the first wireless headset and the second wireless headset by searching for the coding rate corresponding to the obtained parameter values of the multiple quality parameters in the correspondence. Wherein, the higher the parameter values of the quality parameters are, the higher the coding code rate is.
In other embodiments, the first wireless headset may determine whether the current encoding code rate satisfies a first condition according to a plurality of quality parameters, where the first condition is a condition for smooth transmission when audio data encoded according to the current encoding code rate is transmitted to the electronic device under the obtained plurality of quality parameters; if the current coding rate does not meet the first condition, the coding rate can be reduced to avoid jamming during transmission; if the current coding rate meets the first condition, further judging whether the current coding rate meets a second condition, wherein the second condition is a condition for smooth transmission when the current coding rate is transmitted to the electronic equipment under the acquired multiple quality parameters after the coding rate is increased; if the current coding rate meets the second condition, the coding rate can be increased so as to improve the quality of the audio data transmitted to the electronic equipment; if the current coding rate does not satisfy the second condition, the current coding rate can be kept unchanged.
Of course, the specific manner of determining the target code rate by the first wireless earphone according to the multiple quality parameters may not be limited. For example, the first wireless earphone may determine whether the plurality of quality parameters satisfy the corresponding parameter conditions, and determine the corresponding code rate as the target code rate according to the determination result.
Step S240: and respectively controlling the first wireless earphone and the second wireless earphone to encode the collected audio data at the target code rate.
In this embodiment of the present application, after the first wireless headset determines the target code rate, the first wireless headset and the second wireless headset may be respectively controlled to encode the acquired audio data at the target code rate. Optionally, if the current coding rate is different from the target coding rate, the first wireless headset may be controlled to adjust the coding rate to the target coding rate; additionally, the target code rate may be sent to the second wireless headset to instruct the second wireless headset to adjust the coding code rate to the target code rate.
In some embodiments, if the same logic that determines the corresponding code rate as the target code rate according to the multiple quality parameters is set in both the first wireless earphone and the second wireless earphone, the multiple quality parameters may also be sent to the second wireless earphone when controlling the coding rate of the second wireless earphone, so that the second wireless earphone may determine the code rate corresponding to the multiple quality parameters according to the logic and then adjust the coding rate to the code rate.

In this embodiment, each quality parameter of the plurality of quality parameters acquired by the first wireless headset may correspond to a preset parameter condition, where the preset parameter condition is used to determine whether the quality parameter satisfies smooth transmission of audio data to the electronic device. The first wireless headset may match each quality parameter with a preset parameter condition corresponding to each quality parameter, and then determine the number of quality parameters satisfying the corresponding preset parameter condition. It is understood that the greater the number of quality parameters satisfying the preset parameter condition, the better the communication quality of the wireless communication between the first wireless headset and the electronic device.
In some embodiments, the preset parameter condition may be a parameter value condition. Each quality parameter may correspond to a plurality of parameter values, for example, each quality parameter is a plurality of parameter values of the type of quality parameter acquired within a preset time period. The first wireless earphone may obtain a target parameter value corresponding to each quality parameter based on a plurality of parameter values corresponding to each quality parameter; matching a target parameter value corresponding to each quality parameter with a corresponding parameter value condition, wherein each quality parameter corresponds to one parameter value condition; and acquiring the quantity of target quality parameters in the multiple quality parameters, wherein the target parameter values of the target quality parameters are matched with the corresponding parameter value conditions. Alternatively, the first wireless headset may obtain the target parameter value corresponding to each quality parameter based on a plurality of parameter values corresponding to each quality parameter, where an average value of the plurality of parameter values corresponding to each quality parameter is obtained as the target parameter value corresponding to each quality parameter.
It can be understood that, different types of quality parameters have different parameter values, so that corresponding parameter value conditions need to be set for different quality parameters. For example, when the quality parameter is the received signal strength, the parameter value condition may be: the intensity of the received signal is-105 dBm (decibel-milliwatt) -95 dBm; when the quality parameter is the retransmission rate, the parameter value condition may be: the retransmission rate is less than 0.05. Of course, the specific parameter value conditions may not be limited, and may be set according to actual requirements.
In one possible implementation, the first wireless headset may obtain a target parameter value corresponding to each quality parameter and a variation trend corresponding to each quality parameter based on a plurality of parameter values corresponding to each quality parameter; matching a target parameter value corresponding to each quality parameter with a corresponding parameter value condition, wherein each quality parameter corresponds to one parameter value condition; and acquiring the quantity of target quality parameters in the multiple quality parameters, wherein the target parameter values of the target quality parameters are matched with the corresponding parameter value conditions, and the variation trend corresponding to the target quality parameters is not a reduction trend. In this embodiment, the plurality of parameter values corresponding to each quality parameter may be parameter values obtained within a preset time period, and the first wireless headset may further determine a variation trend of each quality parameter based on the plurality of parameter values corresponding to each quality parameter, and determine the number of quality parameters satisfying the corresponding preset parameter condition by integrating whether each quality parameter satisfies the corresponding parameter value condition and the variation trend of each quality parameter. It can be understood that, for a certain quality parameter, if it simultaneously satisfies the corresponding parameter value condition and the trend of the change is not a decreasing trend, it indicates that the communication quality represented by the quality parameter is better.
Step S340: and determining a corresponding coding rate as a target coding rate based on the number, wherein the coding rate is positively correlated with the number.
In this embodiment of the present application, after the first wireless headset determines the number of quality parameters satisfying the corresponding preset parameter condition, the first wireless headset may determine, based on the number, the corresponding coding rate as the target rate. Since the larger the determined above number is, the better the communication quality of the communication between the first wireless headset and the electronic device is, the coding rate may be positively correlated with the number, that is, the larger the number is, the better the communication quality is, and thus the higher the coding rate is.
In some embodiments, the first wireless headset stores a corresponding relationship between the coding rate and the number, and the first wireless headset may determine the coding rate corresponding to the number determined above by looking up the corresponding relationship, and use the coding rate as the target rate.
Illustratively, the coding rate in different cases is illustrated with various quality parameters including the received signal strength and the retransmission rate. Wherein, the coding rate includes three ranges, 100-200 kbps, 200-300 kbps, and 300-400 kbps; when the recording is started, the initial compression code rate is set to be the highest, namely the communication quality is better under the general condition, at the moment, the high code rate is adopted for coding, and the recorded sound quality is the best; in the subsequent recording process, determining an encoding code rate according to the number of parameters meeting the corresponding preset parameter conditions in the received signal strength and the retransmission rate, wherein if the received signal strength and the retransmission rate both meet the corresponding preset parameter conditions, the encoding code rate can be 300-400 kbps; if one of the received signal strength and the retransmission rate meets the corresponding preset parameter condition, the coding code rate can be 200-300 kbps; if the received signal strength and the retransmission rate do not correspond to the preset parameter condition, the coding rate can be 100-200 kbps.

In some embodiments, when the first wireless headset determines the coding rate according to the multiple quality parameters, the coding rates for coding by the first wireless headset and the second wireless headset may be the same or different. Optionally, the first wireless headset may further obtain a communication quality parameter of wireless communication with the second wireless headset, and then determine, according to the communication quality parameter, a corresponding coding rate as the first coding rate, where the mode of determining the coding rate may refer to the mode of determining the coding rate according to the communication quality parameter; if the first code rate is the same as the target code rate, the first wireless earphone and the second wireless earphone can be controlled to carry out coding at the target code rate; if the first code rate is less than the target code rate, the second wireless earphone can be controlled to encode at the first code rate, the first wireless earphone is controlled to encode at the target code rate, and when the audio data of the second wireless earphone and the audio data of the first wireless earphone are combined, the audio data sent by the second wireless earphone can be adjusted to the audio data at the target code rate and then combined to obtain the audio data at the target code rate, so that the smooth transmission of the audio data between the second wireless earphone and the first wireless earphone can be ensured, and the quality of the audio data obtained after the first wireless earphone is encoded is relatively good; if the first code rate is smaller than the target code rate, it is necessary to preferentially ensure that audio data transmission can be smoothly performed between the first wireless headset and the electronic device, and therefore, the first wireless headset and the second wireless headset can be controlled to perform encoding at the target code rate, and therefore, smooth audio data transmission can be ensured between the second wireless headset and the first wireless headset and between the first wireless headset and the electronic device.
