具体实施方式
为了使本技术领域的人员更好地理解本申请方案，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。
电子设备(例如智能手机、平板电脑等)，已经成为人们日常生活中最常用的消费型电子产品之一，随着无线通信技术的发展，用户在利用电子设备进行录音时，无线耳机因其方便携带等特点得到越来越广泛的应用。其中，真无线立体声(True Wireless Stereo，TWS)耳机由于其佩戴更为舒适、使用方便、不引人注目、更加小巧美观等优秀特性，TWS耳机在耳机市场的占有率逐渐提高。
双耳立体声录音技术(Binaural Audio)是一种高度还原真实听感的录音技术，其通过在人工头部的两只耳朵位置配有麦克风，从而可以捕捉到达每只耳朵位置的声音，两个信号就可以分别在每只耳朵上重现。这种重现不适用单声道播放，如果用扬声器来播放也达不到预期的效果，所以通常会使用耳机，将两只耳朵接收的声信号完全隔离开，这种做法可以使人工头完全复刻听众所听到的内容。
在实现双耳立体声录音时，可以使用TWS耳机的两个耳机分别设置的麦克风(Microphone，MIC)进行收音，可以达到以上双耳录音技术的效果。但是在录制的过程中，用户可能不会一直都保持双耳佩戴，因此会出现从单耳佩戴切换到双耳佩戴，从双耳佩戴切换到单耳佩戴的情况。若出现用户取下单只耳机时仍然使用双耳进行收音，此时被拿下的那只耳机和佩戴的耳机拾取的声场就与实际的声场不相符，导致录制的声场效果产生偏移；而在单耳佩戴过程中，若用户佩戴上另一耳机，还是录制单声道音频，则会导致即使用户双耳佩戴耳机，但却无法录制双耳录音效果的音频，影响用户体验。
针对上述问题，发明人提出了本申请实施例提供的录音方法、装置、无线耳机以及存储介质，可以实现根据第一无线耳机以及第二无线耳机的佩戴状态，对录音模式进行控制，以及对获取到的音频数据进行相应的处理，使得录音模式与佩戴状态匹配，提升了录音方式的灵活性，保证了录音效果。
在介绍本申请实施例的编码控制方法之前，先介绍该编码控制方法对应的应用环境。如图1所示，该编码控制方法对应的应用环境包括录音系统10，录音系统10包括电子设备11、第一无线耳机12和第二无线耳机13。该电子设备11可以是智能手机、平板电脑、电子书、智能穿戴设备等能够运行应用程序、并且具有音频信号采集的功能的设备。第一无线耳机12和第二无线耳机13构成真无线立体声(True Wireless Stereo，TWS)耳机，其中，TWS耳机的左右两只耳机相互独立、无需线缆相连，即可实现左右声道的无线分离。于本申请实施例中，可以通过第一无线耳机12和第二无线耳机13分别采集左右声道的声音。
于本申请实施例中，电子设备11内安装有能够采集音频的应用程序，具体地，该应用程序可以是音频播放软件、视频播放软件或者通话软件或者其他的能够触发音频播放的软件等。第一无线耳机12和第二无线耳机13中可以均设置有音频采集装置，例如，设置有麦克风。第一无线耳机12和第二无线耳机13中可以设置有音频采集装置可以采集音频信号，并且由电子设备11将该音频信号处理之后生成音频文件。当然，电子设备11也可以将需要播放的音频发送给第一无线耳机12和第二无线耳机13中的至少一个，由第一无线耳机12和第二无线耳机13中的至少一个播放语音。
作为一种实施方式，如图2所示，电子设备11能够同时与第一无线耳机12和第二无线耳机 13连接。第一无线耳机12和第二无线耳机13能够直接将音频数据发送至电子设备11，或者，接收电子设备11发送的音频数据进行播放。
作为另一种实施方式，如图3所示，电子设备11与第一无线耳机12通过蓝牙连接，然后，第一无线耳机12再通过蓝牙和第二无线耳机13连接，从而，电子设备11、第一无线耳机12和第二无线耳机13通过组网的方式实现同时连接，即第一无线耳机12作为电子设备11和第二无线耳机13的中继器。
在本申请实施例中，电子设备11、第一无线耳机12和第二无线耳机13通过图3所示的方式连接，则该第一无线耳机12可以作为主耳机，第二无线耳机13可以作为从耳机。
请参阅图4，图4示出了本申请一个实施例提供的编码控制方法的流程示意图。在具体的实施例中，该编码方法可以应用于上述录音系统，具体地，该方法的执行主体可以是第一无线耳机，所述第一无线耳机和所述第二无线耳机均设置有音频采集装置，且第一无线耳机和第二无线耳机采用图4所示的连接方式。下面将针对图4所示的流程进行详细的阐述，所述编码控制方法具体可以包括以下步骤：
步骤S110：获取所述第一无线耳机以及所述第二无线耳机的佩戴状态。
在本申请实施例中，由于TWS耳机的两个无线耳机被用于录音时，用户对无线耳机的佩戴状态可能发生改变，若在录音过程中采用固定的录音模式，则可能导致录音效果受到影响。因此，在录音时，作为与电子设备连接的第一无线耳机(主耳机)可以获取第一无线耳机以及第二无线耳机的佩戴状态，以对录音模式进行控制。
在一些实施方式中，如图5所示，第一无线耳机12的壳体上设置有佩戴检测器121，该佩戴检测器12设置在第一无线耳机12的壳体的指定表面，该指定表面为该第一无线耳机12被佩戴时，耳机头与人耳耳甲腔接触的表面。可选地，可以是在该指定表面开设一个黑色圆孔，这个圆孔内装配的便是一个佩戴检测器121，该佩戴检测器121可以是光感传感器，其包括发光单元和感光单元，该发光单元可以是LED灯，LED灯发出红外光线，透过圆孔上的棱镜片，辐射向耳机外，如果前方有不透明物体阻挡的话，大部分光线会反射回来，感光单元根据反射回来的光线强度来判断是否有物体阻挡，来推断是否处于佩戴状态。同理，第二无线耳机12也可以设置佩戴检测器，并基于该佩戴检测器确定第二无线耳机12是否处于佩戴状态。当然，佩戴检测器的具体类型可以不做限定，佩戴检测器也可以为触摸传感器、压力传感器等。
在该实施方式中，可以预先设置有佩戴检测器对应的状态阈值，可以基于佩戴检测器检测的检测值，与状态阈值进行比较，并根据比较结果，确定无线耳机是否处于佩戴状态。例如，佩戴检测器为光感传感器时，状态阈值为设定的光线强度阈值，若光感传感器检测的光线强度低于设定的光线强度阈值时，则确定无线耳机处于佩戴状态；若光感传感器检测的光线强度大于或等于设定的光线强度阈值时，则确定无线耳机未处于佩戴状态。
在一些实施方式中，第一无线耳机在获取第一无线耳机以及第二无线耳机的佩戴状态时，第一无线耳机可以检测自身的佩戴状态，并从第二无线耳机获取第二无线耳机检测的佩戴状态。也就是说，第一无线耳机以及第二无线耳机可以同时检测佩戴状态，第二无线耳机在检测自身的佩戴状态之后，将检测结果同步给第一无线耳机。
在一些实施方式中，在进行录音时，第一无线耳机可以实时的获取第一无线耳机以及第二无线耳机的佩戴状态，以根据佩戴状态进行后续录音的控制；第一无线耳机也可以按照设置的频率，获取第一无线耳机以及第二无线耳机的佩戴状态，例如，第一无线耳机可以每间隔1秒获取一次第一无线耳机以及第二无线耳机的佩戴状态。
步骤S120：若所述第一无线耳机以及所述第二无线耳机中无线耳机的佩戴状态发生变化，根据所述第一无线耳机以及所述第二无线耳机中处于佩戴状态的无线耳机，调整录音模式。
在本申请实施例中，第一无线耳机在获取到第一无线耳机以及第二无线耳机的佩戴状态后，可以确定第一无线耳机以及第二无线耳机的佩戴状态是否发生变化；若第一无线耳机以及第二无线耳机中有无线耳机的佩戴状态发生变化，则可以对录音模式进行调整。可以理解地，无线耳机在处于佩戴状态时，则用户很大可能期望被佩戴的耳机处于使用状态而采集声音，而未处于佩戴状态的无线耳机，则用户很大可能不进行使用，并且单耳佩戴的状态下，处于佩戴状态的无线耳机与未处于佩戴状态的无线耳机同时进行音频数据采集，实现双声道录音，则容易造成声场不符和偏移，使录音效果受到影响，因此在无线耳机的佩戴状态发生变化时，可以调整录音模式，以使录音模式与第一无线耳机以及第二无线耳机中处于佩戴状态的无线耳机对应。
在一些实施方式中，录音模式可以包括单声道录音的模式以及双声道录音的模式。在无线耳机的佩戴状态发生变化时，根据第一无线耳机以及第二无线耳机中处于佩戴状态的无线耳机，调 整录音模式，可以包括：若第一无线耳机以及第二无线耳机均处于佩戴状态，调整录音模式为双声道录音的模式；若第一无线耳机以及第二无线耳机中其中一个无线耳机未处于佩戴状态，调整录音模式为单声道录音的模式。可以理解地，在其中一个无线耳机处于佩戴模式时，则采用单声道录音的模式，在两个无线耳机均处于佩戴状态时，则采用双声道录音的模式。
在一些实施方式中，录音模式除了单声道录音的模式以及双声道录音的模式以外，还可以包括三个及以上声道的录音模式。其中，录音模式为三个及以上声道的录音模式时，则至少一个无线耳机采集的音频数据可以被作为至少两个声道的音频数据。例如，三声道的录音模式时，第一无线耳机采集的音频数据可以作为其中两个声道的音频数据，第二无线耳机采集的音频数据可以作为另一声道的音频数据。
步骤S130：控制所述处于佩戴状态的无线耳机采集音频数据。
在本申请实施例中，第一无线耳机在确定录音模式后，还可以基于第一无线耳机以及第二无线耳机的佩戴状态，控制处于佩戴状态的无线耳机进行音频数据的采集。
在一些实施方式中，第一无线耳机以及第二无线耳机中的至少一个处于佩戴状态(即双耳佩戴的状态或者单耳佩戴的状态)，并且控制处于佩戴状态的无线耳机进行音频数据的采集，控制未处于佩戴状态的无线耳机不进行音频数据的采集。可以理解地，无线耳机在处于佩戴状态时，则用户很大可能期望被佩戴的耳机处于使用状态而采集声音，因此，可以控制处于佩戴状态的无线耳机进行音频数据的采集；而未处于佩戴状态的无线耳机，则用户很大可能不进行使用，并且单耳佩戴的状态下，处于佩戴状态的无线耳机与未处于佩戴状态的无线耳机同时进行音频数据采集，容易造成声场不符和偏移，使录音效果受到影响，因此可以控制未处于佩戴状态的无线耳机不进行音频数据的采集。
步骤S140：根据所述录音模式，对所述音频数据进行预处理。
在本申请实施例中，第一无线耳机还可以对录音过程中获取到的音频数据，根据录音模式进行预处理。
在一些实施方式中，若录音模式为双声道录音的模式，第一无线耳机以及第二无线耳机同时进行音频数据的采集，此时可以获取到两个声道的音频数据，因此可以进行双声道录音对应的处理。具体地，可以将第一无线耳机以及第二无线耳机采集的音频数据合并后，得到合并后的用于发送至电子设备的音频数据。若录音模式为单声道录音的模式，第一无线耳机以及第二无线耳机中只有一个无线耳机进行音频数据的采集，此时只能获取到一个声道的音频数据，则对采集的音频数据进行单声道录音对应的处理，例如，可以添加单声道标记，以便电子设备获知第一无线耳机发送的音频数据为单声道的音频数据。
在一些实施方式中，若第一无线耳机以及第二无线耳机同时进行音频数据的采集，则第二无线耳机可以将获取的音频数据传输至第一无线耳机，第一无线耳机再对其自身采集的音频数据以及第二无线耳机传输的音频数据进行录音模式对应的预处理，得到处理后的音频数据。若第一无线耳机进行音频数据的采集，第二无线耳机不进行音频数据的采集，则第一无线耳机可以对其采集的音频数据进行录音模式对应的预处理后，得到处理后的音频数据。若第一无线耳机未进行音频数据的采集，第二无线耳机进行音频数据的采集，此时，第一无线耳机只是作为中继耳机，对第二无线耳机传输的音频数据进行录音模式对应的预处理后，得到处理后的音频数据，并且后续将处理后的音频数据传输至电子设备。
步骤S150：将所述预处理后的音频数据传输至电子设备。
在本申请实施例中，第一无线耳机在对获取到的音频数据进行预处理后，则可以将预处理后的音频数据传输至电子设备，以便电子设备根据接收的音频数据生成音频文件。具体地，可以是对音频数据执行编码或者优化处理等操作之后生成指定音频格式的音频文件，该指定音频格式可以是MP3、WAV、FLC等，具体的音频格式可以不做限定。
在一些实施方式中，第一无线耳机在将处理后的音频数据传输至电子设备后，电子设备的无线通信模块(例如蓝牙模块等)接收到该音频数据包之后，进行解码，解码成PCM的数据，给到后处理的算法模块，该后处理的算法模块可以是应用处理器AP内的模块，进行增益调整处理和频率处理的调整后给到录音的APK输出MP3的文件。由此，将后处理的过程设置于电子设备一侧，不仅可以保证录音效果，还能够降低无线耳机的功耗。
其中，增益调整处理包括增益增大操作和动态范围调整(Dynamic Range Control，DRC)，其中，增益增大操作包括对目标声源的音频信号的整个频域或时域部分的增益增大，动态范围调整是指用来动态调整音频输出幅值，在音量大时压制音量在某一范围内，在音量小时适当提升音量。通常用于控制音频输出功率，使扬声器不破音，当处于低音量播放时也能清晰听到。频率处理用 于对目标声源的音频信号的不同频率部分进行处理，例如，EQ和降噪，其中，EQ英文全称Equaliser，即均衡器，用于通过对音频信号的某一个或多个频段进行增益或衰减，从而达到调整音色的目的。降噪可以是滤波，即将音频信号中的部分频段的信号滤除等，以降低音频信号中的噪声。
在一些实施方式中，前一个实施方式中电子设备对音频数据进行后处理的过程也可以设置于无线耳机，其中，第一无线耳机在进行步骤S140中的预处理过程中，也可以进行上述的后处理，即执行上述的增益调整处理和频率处理，以保证录音效果。可选地，第一无线耳机可以获取当前的剩余电量，若剩余电量大于电量阈值，表示当前剩余电量较为充足，因此可以执行如上的后处理，并对后处理后的音频数据中加上第一标记，第一标记用于指示音频数据已被进行后处理，以便电子设备获知音频数据已被进行过后处理，而减小电子设备的处理量；而在剩余电量小于或等于电量阈值时，则对预处理后的音频数据添加第二标记，将已添加第二标记的音频数据传输至电子设备，第二标记用于指示音频数据未被进行后处理，以便电子设备获知音频数据未进行过后处理，从而能够对接收到的音频数据进行上述的后处理。
在一些实施方式中，第一无线耳机将获取的音频数据传输至电子设备时，由于采集音频数据的无线耳机在采集到音频数据后会对音频数据进行编码，因此，第一无线耳机还可以在音频数据中添加码率信息，以便电子设备在接收到音频数据后，可以根据码率信息，获知音频数据的码率，从而在对音频数据进行进一步的处理而生成音频文件时，能够根据码率调整处理时的采样率、位数信息和压缩数据的强度等。
在一些实施方式中，除了控制处于佩戴状态的无线耳机进行音频数据的采集，未处于佩戴状态的无线耳机在满足设定状态条件时也可以进行音频数据的采集。可选地，第一无线耳机以及第二无线耳机均处于佩戴状态，即处于双耳佩戴的状态，则第一无线耳机以及第二无线耳机均可以进行音频数据的采集，即进行双声道的音频数据采集；而当第一无线耳机以及第二无线耳机中只有一个无线耳机处于佩戴状态时，则控制处于佩戴状态的无线耳机进行音频数据的采集，并且未处于佩戴状态无线耳机满足设定状态条件时，也可以进行音频数据的采集，此时可能为单声道的音频数据采集，也可能不为单声道的音频数据采集。可选地，上述设定状态条件可以包括：未处于佩戴状态的无线耳机相对处于佩戴状态的无线耳机的空间位置满足设定的位置条件。其中，该位置条件可以基于双耳佩戴时，无线耳机之间可能存在的相对空间位置设置，可以理解地，用户佩戴第一无线耳机以及第二无线耳机时，随着用户的移动或者头部转动，两个无线耳机之间的相对空间位置可能发生变化，因此可以获取双耳佩戴状态下两个无线耳机之间存在的相对空间位置，确定以上位置条件。其中，若未处于佩戴状态的无线耳机相对处于佩戴状态的无线耳机的空间位置满足设定的位置条件时，虽然其中一个无线耳机未处于佩戴状态，但是，录制的声场也与双耳录音时的声场符合，因此，也可以进行音频数据的采集。可选地，上述设定状态条件可以包括：第二无线耳机处于手持状态。可以理解地，在一些场景中，如图6所示，可能录音的场景为采访的场景，此时，采访者A则可能佩戴第一无线耳机12，而被采访者B则可能手持第二无线耳机13以采集被采访者B的声音。因此，可以确定第二无线耳机是否处于手持状态，以确认是否需要控制第二无线耳机采集音频数据。可选地，第二无线耳机的耳柄的表面可以设置有触摸传感器，以根据触摸传感器检测的数据，确定第二无线耳机是否处于手持状态。
本申请实施例提供的录音方法，在录音过程中，在第一无线耳机以及第二无线耳机中无线耳机的佩戴状态发生变化时，调整录音模式，并对采集音频数据的无线耳机进行控制，并且根据录音模式，对采集的音频数据进行预处理，使得录音模式与佩戴状态匹配，提升了录音模式的灵活性，保证了录音效果。
请参阅图7，图7示出了本申请另一个实施例提供的录音方法的流程示意图。该录音方法应用于上述第一无线耳机，下面将针对图7所示的流程进行详细的阐述，所述录音方法具体可以包括以下步骤：
步骤S210：获取所述第一无线耳机以及所述第二无线耳机的佩戴状态。
步骤S220：若所述第一无线耳机以及所述第二无线耳机中无线耳机的佩戴状态发生变化，根据所述第一无线耳机以及所述第二无线耳机中处于佩戴状态的无线耳机，调整录音模式。
在本申请实施例中，步骤S210以及步骤S220可以参阅前述实施例的内容，在此不再赘述。
步骤S230：若所述第一无线耳机处于佩戴状态且所述第二无线耳机未处于佩戴状态，控制所述第一无线耳机进行音频数据的采集。
在本申请实施例中，第一无线耳机在获取到第一无线耳机以及第二无线耳机的佩戴状态后，若第一无线耳机处于佩戴状态，而第二无线耳机未处于佩戴状态，则可以控制第一无线耳机进行音频数据的采集，而第二无线耳机不进行音频数据的采集。可以理解地，第二无线耳机未佩戴时， 若第一无线耳机以及第二无线耳机同时采集音频数据，进行双耳录音时，则会导致录制的声场与此前不符，产生声场偏移，因此，在第一无线耳机处于佩戴状态，而第二无线耳机未处于佩戴状态时，可以仅控制第一无线耳机进行音频数据的采集。
步骤S240：若所述第一无线耳机以及所述第二无线耳机均处于佩戴状态，控制所述第一无线耳机以及所述第二无线耳机均进行音频数据的采集。
在本申请实施例中，第一无线耳机在获取到第一无线耳机以及第二无线耳机的佩戴状态后，若第一无线耳机以及第二无线耳机均处于佩戴状态，则TWS耳机处于双耳佩戴的状态，此时，可以控制第一无线耳机以及第二无线耳机均进行音频数据的采集，以实现双耳录音的效果。
在一些实施方式中，第一无线耳机在获取到第一无线耳机以及第二无线耳机的佩戴状态后，若第一无线耳机未处于佩戴状态，而第二无线耳机处于佩戴状态，此时，由于第一无线耳机为与电子设备连接的主耳机，而当前主耳机未处于佩戴状态，因此可以切换主耳机为第二无线耳机，并通过第二无线耳机进行音频数据的采集，以减少音频数据的传输时间。
步骤S250：根据所述录音模式，对所述音频数据进行预处理。
步骤S260：将所述预处理后的音频数据传输至所述电子设备。
在本申请实施例中，步骤S250以及步骤S260可以参阅其他实施例的内容，在此不再赘述。
本申请实施例提供的录音方法，在录音过程中，根据无线耳机的佩戴状态的变化，调整录音模式，并且在两者同时处于佩戴状态时，控制两者同时进行音频数据的采集，而作为主耳机的第一无线耳机处于佩戴状态，且第二无线耳机未处于佩戴状态时，仅控制第一无线耳机进行音频数据的采集，使得录音模式与佩戴状态匹配，提升了录音模式的灵活性，保证了录音效果。
请参阅图8，图8示出了本申请又一个实施例提供的录音方法的流程示意图。该录音方法应用于上述无线耳机，下面将针对图8所示的流程进行详细的阐述，所述录音方法具体可以包括以下步骤：
步骤S310：获取所述第一无线耳机以及所述第二无线耳机的佩戴状态。
步骤S320：若所述第一无线耳机以及所述第二无线耳机中无线耳机的佩戴状态发生变化，根据所述第一无线耳机以及所述第二无线耳机中处于佩戴状态的无线耳机，调整录音模式。
在本申请实施例中，步骤S310以及步骤S320可以参阅前述实施例的内容，在此不再赘述。
步骤S330：若所述第一无线耳机处于佩戴状态且所述第二无线耳机未处于佩戴状态，控制所述第一无线耳机进行音频数据的采集。
在本申请实施例中，录音过程中，若第一无线耳机处于佩戴状态，且第二无线耳机由佩戴状态变为未佩戴状态时，则可以采用单声道录音的模式进行录音，此时，可以控制第一无线耳机进行音频数据的采集，而第二无线耳机不进行音频数据的采集，以避免录制的声场发生偏移，影响录音效果。该情况下，直接切换为单声道录音的模式，并且第一无线耳机持续进行音频数据的采集，因此不会出现延时或中断。
步骤S340：若所述第一无线耳机处于佩戴状态，且所述第二无线耳机由未佩戴状态变为佩戴状态时，控制所述第一无线耳机进行音频数据的采集。
在本申请实施例中，录音过程中，第一无线耳机在获取到第一无线耳机以及第二无线耳机的佩戴状态后，若第一无线耳机处于佩戴状态，而第二无线耳机未处于佩戴状态，控制第一无线耳机进行音频数据的采集，此时为单声道录音的模式。并且，第一无线耳机处于佩戴状态，第二无线耳机由未佩戴状态变为佩戴状态时，则需要进行双声道录音，此时，可以保持第一无线耳机进行音频数据的采集，并且需要控制第二无线耳机进行音频数据的采集。
在一些场景中，如图9所示，用户同时佩戴第一无线耳机12以及第二无线耳机13进行录音，此时第一无线耳机以及第二无线耳机同时进行音频数据的采集，实现双耳录音；如图10所示，在用户将第二无线耳机13摘下后，则可以仅控制第一无线耳机12进行音频数据的采集，实现单声道录音。
步骤S350：获取用于同步所述第一无线耳机与所述第二无线耳机采集的音频数据的同步信息，所述同步信息用于所述第一无线耳机与所述第二无线耳机对采集的音频数据进行同步。
在本申请实施例中，在第一无线耳机处于佩戴状态，而第二无线耳机由未佩戴状态变为佩戴状态时，由于此前第二无线耳机并未进行音频数据的采集，为了保证录制双声道的音频数据时，后续发送至电子设备的音频数据中双声道的音频数据同步，即保证发送至电子设备的音频数据中双声道的音频数据为同时间采集的音频数据，因此，可以对第一无线耳机以及第二无线耳机进行采集的音频数据进行同步。具体地，第一无线耳机可以获取用于同步第一无线耳机与第二无线耳机采集的音频数据的同步信息，该同步信息用于第一无线耳机与第二无线耳机对采集的音频数据 进行同步，以保证发送至电子设备的音频数据中双声道的音频数据为同时间采集的音频数据。
在一些实施方式中，请参阅图11，获取用于同步所述第一无线耳机与所述第二无线耳机采集音频数据的同步信息，可以包括：
步骤S351：获取所述第一无线耳机以及所述第二无线耳机进行音频数据采集的同步时间，所述同步时间用于所述第二无线耳机控制开始进行音频数据的时间。
在该实施方式中，第一无线耳机可以获取第一无线耳机以及第二无线耳机进行音频数据采集的同步时间，以便第二无线耳机控制其何时开始录音，以及第一无线耳机后续可以获知第二无线耳机采集的音频数据是何时开始录制的，从而保证两者采集的音频数据的同步。
可选地，获取所述第一无线耳机以及所述第二无线耳机进行音频数据采集的同步时间，可以包括：获取所述第二无线耳机启动录音所需的时长作为第一时长；获取发送待生成的同步信息至所述第二无线耳机的时长作为第二时长；基于当前时刻、所述第一时长以及所述第二时长，生成所述同步时间。该方式中，第一无线耳机在确定以上同步时间时，可以获取第二无线耳机启动录音过程所需要花费的时长，例如，开启麦克风、设置编码器的过程等；并且可以获取后续确定同步信息后，同步信息发送至第二无线耳机的时长，然后在当前时刻的基础上，加上第一时长以及第二时长，即得到同步录音的同步时间(时刻)。也就是说，在该同步时间时，第二无线耳机进行音频数据的采集，并且第一无线耳机能够同样获知在该同步时间的时间点之后所采集的音频数据，以便第一无线耳机后续能够对第二无线耳机开始录音时所发送的音频数据，与其自身采集的音频数据进行比对和合并后，发送至电子设备，保证发送至电子设备的双声道的音频数据所被无线耳机采集的时间是一致的。
步骤S352：获取所述第一无线耳机以及所述第二无线耳机同步音频数据包的数据包序号，所述数据包序号用于所述第二无线耳机对采集到的音频数据包进行编号。
在该实施方式中，由于无线耳机在采集音频数据时，通常会将采集的音频数据编码成不同的数据包，因此，在录音过程中，第一无线耳机可以对获取的数据包进行编号。在第二无线耳机由未佩戴状态变为佩戴状态时，则可以获取第一无线耳机以及第二无线耳机同步音频数据包的数据包序号，以便第二无线耳机将相同时间获取的音频数据包，编号为第一无线耳机在相同时间获取的音频数据包的序号。
可选地，第一无线耳机可以基于当前采集的音频数据的数据包序号以及同步时间，获取第一无线耳机在同步时间时，对采集到的音频数据包进行编号后的数据包序号，作为第一无线耳机以及第二无线耳机同步音频数据包的数据包序号。其中，第一无线耳机可以根据同步时间和数据包序号，按照编码音频数据得到数据包的速度，预估在同步时间时对音频数据包进行编号后的序号。
步骤S353：基于所述同步时间以及所述数据包序号生成所述同步信息。
在得到同步时间以及数据包序号后，则可以基于同步时间以及数据包序号生成同步信息，同步信息中包括该同步时间以及数据包序号。
当然，第一无线耳机与第二无线耳机采用其他的方式对采集的音频数据进行同步时，也可以根据其采用的其他方式来生成对应的同步信息。

请参阅图13，图13示出了本申请再一个实施例提供的录音方法的流程示意图。该录音方法应用于上述无线耳机，下面将针对图13所示的流程进行详细的阐述，所述录音方法具体可以包括以下步骤：
步骤S410：获取所述第一无线耳机以及所述第二无线耳机的佩戴状态。
步骤S420：若所述第一无线耳机以及所述第二无线耳机中无线耳机的佩戴状态发生变化，根据所述第一无线耳机以及所述第二无线耳机中处于佩戴状态的无线耳机，调整录音模式。
在本申请实施例中，步骤S410以及步骤S420可以参阅前述实施例的内容，在此不再赘述。
步骤S430：若所述第一无线耳机由佩戴状态变为未佩戴状态，且所述第二无线耳机为佩戴状态，断开与所述电子设备的连接。
在本申请实施例中，录音过程中，第一无线耳机在获取到第一无线耳机以及第二无线耳机的佩戴状态后，若第一无线耳机由佩戴状态变为未佩戴状态，而第二无线耳机为佩戴状态，此时，需要第二无线耳机进行音频数据的采集，而第一无线耳机不进行音频数据的采集。该情况下，若仍将第一无线耳机作为主耳机与电子设备进行连接，则第二无线耳机采集的音频数据仍然需要通过第一无线耳机进行中转，进而导致音频数据传输至电子设备的效率较低。因此，在检测出第一无线耳机由佩戴状态变为未佩戴状态，而第二无线耳机为佩戴状态，则可以断开与电子设备的连接。
步骤S440：向所述第二无线耳机发送切换指令，所述切换指令用于指示所述第二无线耳机与所述电子设备连接，进行音频数据的采集，以及根据所述录音模式对采集的音频数据进行所述预处理后传输至所述电子设备。
在本申请实施例中，第一无线耳机在断开与电子设备的连接的同时，可以向第二无线耳机发送切换指令，第二无线耳机在接收到切换指令后，则可以响应该切换指令，与电子设备连接，并且进行音频数据的采集，以及根据录音模式对采集的音频数据进行预处理后传输至电子设备，由此实现第一无线耳机被用户从耳朵取下，第二无线耳机被佩戴时的单声道录音的模式。
在一些场景中，用户可能仅佩戴第一无线耳机进行录音，此时仅控制第一无线耳机进行音频数据的采集，实现单声道录音；若用户将第一无线耳机摘下，并且将第二无线耳机戴上，此时第一无线耳机由佩戴状态变为未佩戴状态，而第二无线耳机为佩戴状态，则进行步骤S430以及步骤S440的处理。
在一些场景中，用户可能同时佩戴第一无线耳机进行录音，此时同时控制第一无线耳机以及第二无线耳机进行音频数据的采集，实现双声道录音；若用户将第一无线耳机摘下，并且将第二无线耳机戴上，此时第一无线耳机由佩戴状态变为未佩戴状态，而第二无线耳机为佩戴状态，则进行步骤S430以及步骤S440的处理。
步骤S450：若所述第一无线耳机处于佩戴状态且所述第二无线耳机未处于佩戴状态，控制所述第一无线耳机进行音频数据的采集。
步骤S460：若所述第一无线耳机以及所述第二无线耳机均处于佩戴状态，控制所述第一无线耳机以及所述第二无线耳机均进行音频数据的采集。
步骤S470：根据所述录音模式，对所述音频数据进行预处理。
步骤S480：将所述预处理后的音频数据传输至所述电子设备。
在本申请实施例中，步骤S450至步骤S480可以参阅其他实施例的内容，在此不再赘述。
本申请实施例提供的录音方法，在录音过程中，作为主耳机的第一无线耳机根据第一无线耳 机以及第二无线耳机的佩戴状态，在佩戴状态发生变化时，调整录音模式，并且控制采集音频数据的无线耳机，以使录音模式与佩戴状态匹配，提升了录音模式的灵活性，保证了录音效果。另外，第二无线耳机处于佩戴状态，而第一无线耳机由佩戴状态变为佩戴状态时，进行主耳机的切换，将主耳机切换为第二无线耳机，使第二无线耳机将采集的音频数据传输至电子设备时，无需再通过第一无线耳机进行中转，提升音频数据的传输效率。
请参阅图14，图14示出了本申请又另一个实施例提供的录音方法的流程示意图。该录音方法应用于上述无线耳机，下面将针对图14所示的流程进行详细的阐述，所述录音方法具体可以包括以下步骤：
步骤S510：获取所述第一无线耳机以及所述第二无线耳机的佩戴状态。
步骤S520：若所述第一无线耳机以及所述第二无线耳机中无线耳机的佩戴状态发生变化，根据所述第一无线耳机以及所述第二无线耳机中处于佩戴状态的无线耳机，调整录音模式。
步骤S530：控制所述处于佩戴状态的无线耳机采集音频数据。
在本申请实施例中，步骤S510至步骤S530可以参阅前述实施例的内容，在此不再赘述。
步骤S540：若所述录音模式为单声道录音的模式，且所述音频数据为采集的第一个音频数据包，对所述音频数据添加第二指示信息，得到第二目标数据包，所述第二指示信息用于指示当前为单声道录音。
在一些实施方式中，在对获取到的音频数据进行单声道录音的模式对应的预处理时，若获取到的第三音频数据包为第一无线耳机以及第二无线耳机中采集音频数据的无线耳机所采集的第一个音频数据包，则可以对第三音频数据包添加第二指示信息，得到第二目标数据包，第二指示信息用于指示当前为单声道录音。从而电子设备在获取到发送的第二目标数据包之后，则可以获知当前第一无线耳机采集的音频数据为单声道录音的音频数据，因此，后续电子设备可以复制该音频数据作为另一声道的音频数据，即两个声道使用相同数据，再根据两个声道的音频数据生成音频文件。
示例性地，请参阅图15，图15示出了第一无线耳机作为主耳机进行音频数据的采集，电子设备为手机，实现单耳录音时的录音的原理。其中，主耳机可以将麦克风采集的音频数据进行OPUS编码后，将编码得到的音频数据包放入主缓冲区，并通过帧头信息控制模块，对单耳录音时产生的第一个音频数据包加入以上第二指示信息；后续主耳机通过从主缓冲区中取出音频数据包后，发送至手机蓝牙；在手机蓝牙将音频数据包传给Audio之前，解析出的第二指示信息如果指示是单声道录音，则复制该数据做为另一个声道数据，即左右声道使用相同数据，然后再将处理后的数据发送给手机Audio模块，以生成音频文件。
在另一些实施方式中，若第一无线耳机以及第二无线耳机中其中一个无线耳机采集音频数据，也可以将获取到的音频数据包作为双声道的音频数据，对所双声道的音频数据进行合成，得到第三目标数据包。也就是说，第一无线耳机作为主耳机可以复制得到的音频数据包，作为另一个声道的音频数据包，即两个声道使用相同的音频数据，然后再将音频数据包合并成一个数据包(第三目标数据包)，后续发送至电子设备。
步骤S550：若所述录音模式为双声道录音的模式，将所述第一无线耳机采集的第一音频数据包存储于第一缓冲区，将接收到的所述第二无线耳机采集的第二音频数据包存储于第二缓冲区。
在本申请实施例中，第一无线耳机以及第二无线耳机均进行音频数据的采集时，第一无线耳机以及第二无线耳机中均设置有缓冲区，其中，第一无线耳机中的缓冲区为第一缓冲区和第二缓冲区，第二无线耳机中的缓冲区为第三缓冲区。第二无线耳机在录音时，对采集的音频数据进行编码后得到的第二音频数据包，可以将第二音频数据包放入第三缓冲区；第一无线耳机对采集的音频数据进行编码后得到的第一音频数据包，可以将第一音频数据包放入第一缓冲区。第二无线耳机将第三缓冲区中的第二音频数据包发送至第一无线耳机后，第一无线耳机将第二音频数据包存储于第二缓冲区中，后续进行上行数据的发送流程。
步骤S560：将所述第一音频数据包以及所述第二音频数据包合并，得到第一目标数据包。
在本申请实施例中，在进行上行数据的发送时，第一无线耳机可以将第一缓冲区中的第一音频数据包与第二缓冲区中的第二音频数据包取出，然后将第一音频数据包以及第二音频数据包合并为同一个音频数据包之后，发送至电子设备。
在一些实施方式中，第一无线耳机以及第二无线耳机均进行音频数据的采集，实现双耳录音时，需要保证第一无线耳机以及第二无线耳机获取的音频数据包之间同步，也就是说，第一无线耳机需要合并的第一音频数据包与第二音频数据包对应的采集时间需要同步一致，以保证合并后的音频数据包的真实性。可选地，基于第一音频数据包的第一时间戳和第二音频数据包的第二时 间戳，若第一时间戳与第二时间戳一致，则可以将第一音频数据和第二音频数据整合成一个音频数据包。
在另一些实施方式中，第一无线耳机也可以在开始进行双耳录音时，即开始执行第一无线耳机和第二无线耳机同时进行音频数据的采集时，对首个音频数据包进行同步，后续的音频数据包则可以直接进行合并。其中，若第一音频数据包以及第二音频数据包为录音的过程中的第一个音频数据包，则可以根据第一音频数据包以及第二音频数据包中的同步信息，对第一音频数据包以及第二音频数据包进行比对；若第一音频数据包与第二音频数据包匹配，则将第一音频数据包以及第二音频数据包合并后发送至电子设备。对于后续获取的音频数据包，可以按照获取时的时间先后顺序，对第一无线耳机以及第二无线耳机所分别获取的音频数据包进行合并后，传输至电子设备。
在一些实施方式中，若第二音频数据包为第二无线耳机发送的第一个音频数据包，将第一音频数据包以及第二音频数据包合并，以及添加第一指示信息，得到第一目标数据包，第一指示信息用于指示当前为双声道录音。从而电子设备在获取到发送的第一目标数据包之后，则可以根据第一指示信息获知当前第一无线耳机采集的音频数据为双声道录音的音频数据，并据此进行后处理，生成相应的音频文件。
在一些实施方式中，在第一无线耳机以及第二无线耳机同时进行音频数据采集的情况下，若第一无线耳机根据获取到的第一无线耳机以及第二无线耳机的佩戴状态，确定出第一无线耳机由佩戴状态变为未佩戴状态，且第二无线耳机为佩戴状态时，此时执行上个实施例中步骤S430以及步骤S440所述的主耳机切换流程，而在切换时，第一无线耳机在断开时，其缓冲区中的音频数据并未发送至电子设备，导致音频数据的丢失。针对该问题，第一无线耳机可以将未发送至电子设备的音频数据，发送至第二无线耳机，并且第二无线耳机可以将第一无线耳机断开与电子设备的连接时，至第二无线耳机建立起与电子设备连接的过程中所采集的音频数据进行缓存，第二无线耳机在建立起与电子设备连接之后，可以将第一无线耳机发送的音频数据传输至电子设备之后，再将切换过程采集的音频数据传输至电子设备，由此，可以保证主耳机切换时音频数据不会发生丢失。
在该实施方式中，第二无线耳机在建立起与电子设备的连接时，即主耳机切换完成时，还可以增大与电子设备之间的信道的带宽，以及增大其无线通信的发射功率，例如，增大蓝牙发射功率，以便将第一无线耳机发送的音频数据更快地传输至电子设备，保证后续采集的音频数据能够及时的传输至电子设备。
步骤S570：将所述预处理后的音频数据传输至所述电子设备。
在本申请实施例中，步骤S570可以参阅其他实施例的内容，在此不再赘述。
本申请实施例提供的录音方法，在录音过程中，作为主耳机的第一无线耳机根据第一无线耳机以及第二无线耳机的佩戴状态，控制采集音频数据的无线耳机，以使录音方式与佩戴状态匹配，并且，在控制采集音频数据的无线耳机后，还根据当前采集音频数据的无线耳机，进行单声道录音或者双声道录音对应的处理，实现了录音方式与佩戴状态相匹配。提升了录音方式的灵活性，保证了录音效果。
