具体实施方式Detailed ways

为使本发明的上述目的、特征和优点能够更加明显易懂，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述。显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动的前提下所获得的所有其它实施例，均属于本发明保护的范围。In order to make the above objects, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, but not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

实施例一Example 1

首先，应当理解的是，倘若用户想在智能设备上体验立体环绕音效，通常需要配置多个喇叭，例如杜比5.1声道具有中央声道、前置左右声道、后置左右环绕声道以及重低音声道等，7.1声道更是在此基础上增加了中左声道和中右声道，但是，配置的提升意味着成本的提升，对于绝大部分用户来说，常用的智能设备的配置难以达到上述要求，例如，假设用户的智能设备为2.0声道，若想体验5.1声道的音效效果，则需要将多声道音效转化为双声道的立体音效，目前，通常采用的方式是声道映射和按照标准缩混公式进行调试的方式，前者即将中央声道、前置左声道和后置声道混成左声道，将中央声道、前置右声道和后置右声道混成右声道，但是，该方式会导致中央声道的音效缺失，后者即将多声道的音频数据缩混至两声道的音频数据，但是由于标准缩混公式的缩混系数统一化，进而缩混后呈现的立体音亦无法满足所有用户的需求，与此同时，缩混的过程中还会导致声音细节的丢失，也即，当前技术将多声道音频音效优化为立体环绕音效的优化效果差，所以，目前亟需一种提升将多声道音频音效优化为立体环绕音效的调试效果的音频播放优化方法。First of all, it should be understood that if users want to experience stereo surround sound on smart devices, they usually need to configure multiple speakers. For example, Dolby 5.1 channel has center channel, front left and right channels, rear left and right surround channels and Subwoofer channels, etc. The 7.1 channel adds a center left channel and a center right channel on this basis. However, the improvement of the configuration means the increase of the cost. For most users, the commonly used smart devices It is difficult to meet the above requirements in the configuration of the user's smart device. For example, if the user's smart device is 2.0-channel, if you want to experience the 5.1-channel sound effect, you need to convert the multi-channel sound into two-channel stereo sound. The method is channel mapping and debugging according to the standard downmixing formula. The former mixes the center channel, the front left channel and the rear channel into the left channel, and the center channel, the front right channel and the rear channel. The right channel is mixed into the right channel, but this method will result in the loss of the sound effect of the center channel. The latter is to downmix the multi-channel audio data to the two-channel audio data, but due to the downmixing coefficient of the standard downmixing formula Unification, and then the stereo sound presented after downmixing cannot meet the needs of all users. At the same time, the process of downmixing will lead to the loss of sound details, that is, the current technology optimizes the multi-channel audio sound effects to stereo The optimization effect of surround sound effects is poor. Therefore, there is an urgent need for an audio playback optimization method for improving the debugging effect of optimizing multi-channel audio effects into stereo surround sound effects.

在本实施例中，需要说明的是，所述音频播放优化方法应用于智能设备，所述智能设备为无法自主生成立体环绕音效的音频播放设备，具体可以为智能电视、显示器、盒子、投影仪、车机、平板电脑以及智能手机等等，所述待缩混音频数据由用户输入的音频播放优化指令获取，所述音频播放优化指令为将所述智能设备的音效效果优化为立体环绕音效的指令，可由用户的触发操作触发生成，例如，检测到用户进行了按钮点击操作或输入了键盘指令等。In this embodiment, it should be noted that the audio playback optimization method is applied to a smart device, and the smart device is an audio playback device that cannot generate stereo surround sound independently, specifically a smart TV, a display, a box, a projector , car machine, tablet computer, smart phone, etc., the audio data to be downmixed is obtained by the audio playback optimization instruction input by the user, and the audio playback optimization instruction is to optimize the sound effect of the smart device to a stereo surround sound effect. The instruction can be triggered and generated by a user's trigger operation, for example, it is detected that the user has performed a button click operation or input a keyboard instruction.

另外地，需要说明的是，所述待缩混音频数据为等待进行缩混的音频数据，也即，初始音频数据，具体为所述智能设备具备的预设数量的声道的音频数据，例如，假设所述智能设备具备X、Y和Z三个声道，则分别收集声道X的音频数据、声道Y的音频数据和声道Z的音频数据，并将其共同作为待缩混音频数据。In addition, it should be noted that the audio data to be downmixed is the audio data waiting to be downmixed, that is, the initial audio data, specifically the audio data of the preset number of channels possessed by the smart device, such as , assuming that the intelligent device has three channels of X, Y and Z, then collect the audio data of channel X, the audio data of channel Y and the audio data of channel Z respectively, and use them as the audio data to be downmixed. data.

另外地，需要说明的是，所述初始调试缩混系数与所述待缩混音频数据对应，用于将多声道的待缩混音频数据进行缩混，其中，由所述初始调试缩混系数构成的缩混公式用于将多声道的待缩混音频数据缩混至双声道的缩混后的音频数据，具体为电声工程师依据专业标准修改标准缩混公式中各待缩混音频数据对应的缩混系数，所以，所述初始调试缩混系数为标准缩混公式中用户修改后的缩混系数，其中，所述初始调试缩混系数中包括已修改的缩混系数和未修改的缩混系数，所述已修改的缩混系数为电声工程师根据专业经验修改的缩混系数，所述未修改的缩混系数为标准缩混公式中常规缩混系数，在一种可实施的方式中，假设待缩混音频数据包括声道A的音频数据、声道B的音频数据、声道C的音频数据、声道D的音频数据和声道E的音频数据，其中，声道A的音频数据在标准缩混公式中对应的常规缩混系数为a，基于上述，声道B的音频数据对应常规缩混系数b，声道C的音频数据对应常规缩混系数c，声道D的音频数据对应常规缩混系数d，声道E的音频数据对应常规缩混系数e，若电声工程师依据专业经验将常规缩混系数c调整为m，常规系数e调整为n，则常规缩混系数a、常规缩混系数b、常规缩混系数d、调整后的缩混系数m和调整后的缩混系数n共同作为初始调试缩混系数，其中，已修改的缩混系数为声道C的音频数据对应的缩混系数和声道E的音频数据对应的缩混系数，未修改的缩混系数为常规缩混系数a、常规缩混系数b和常规缩混系数d，其中，缩混系数具体数值可以为0.1、0.2以及0.3等等。In addition, it should be noted that the initial debug downmix coefficient corresponds to the audio data to be downmixed, and is used to downmix the multi-channel audio data to be downmixed, wherein the initial debug downmix is The downmixing formula composed of coefficients is used to downmix the multi-channel audio data to be downmixed to the two-channel downmixed audio data. Specifically, the electroacoustic engineer modifies each downmixing formula in the standard downmixing formula according to professional standards. The downmix coefficient corresponding to the audio data, therefore, the initial debug downmix coefficient is the downmix coefficient modified by the user in the standard downmix formula, wherein the initial debug downmix coefficient includes the modified downmix coefficient and the unmodified downmix coefficient. The modified downmixing coefficient, the modified downmixing coefficient is the downmixing coefficient modified by electroacoustic engineers according to professional experience, and the unmodified downmixing coefficient is the conventional downmixing coefficient in the standard downmixing formula, in a possible In the implementation manner, it is assumed that the audio data to be downmixed includes the audio data of channel A, the audio data of channel B, the audio data of channel C, the audio data of channel D, and the audio data of channel E, wherein the audio data is The conventional downmixing coefficient corresponding to the audio data of channel A in the standard downmixing formula is a. Based on the above, the audio data of channel B corresponds to the conventional downmixing coefficient b, the audio data of channel C corresponds to the conventional downmixing coefficient c, and the audio data of channel C corresponds to the conventional downmixing coefficient c. The audio data of channel D corresponds to the conventional downmixing coefficient d, and the audio data of channel E corresponds to the conventional downmixing coefficient e. If the electroacoustic engineer adjusts the conventional downmixing coefficient c to m and the conventional coefficient e to n according to professional experience, then The conventional downmixing coefficient a, the conventional downmixing coefficient b, the conventional downmixing coefficient d, the adjusted downmixing coefficient m and the adjusted downmixing coefficient n are taken together as the initial debugging downmixing coefficient, wherein the modified downmixing coefficient is The downmixing coefficient corresponding to the audio data of channel C and the downmixing coefficient corresponding to the audio data of channel E, the unmodified downmixing coefficients are the conventional downmixing coefficient a, the conventional downmixing coefficient b and the conventional downmixing coefficient d, wherein , and the specific value of the downmixing coefficient can be 0.1, 0.2, 0.3 and so on.

另外地，需要说明的是，由于初始调试缩混系数为电声工程师根据专业经验为各声道的音频系数设置特定的缩混系数，也即，依据初始调试缩混系数缩混后的音频数据，能够满足大部分用户对于预期音效效果的需求，也即，所述初始调试缩混系数可以为具备预设音效效果的缩混系数，也可以为仍需用户根据自身需求进行调试的缩混系数，于标准缩混公式对多声道的音频数据进行缩混时，会选择性放弃低音通道的音频数据，进而导致缩混后的音频数据所呈现的音效效果很难达到用户的预期，进而在缩混后需增加低音数据流，以减少缩混损失，所以，所述缩混后音频数据为增加低音音频数据的缩混后的音频数据。In addition, it should be noted that, since the initial debugging downmixing coefficient is the electroacoustic engineer setting a specific downmixing coefficient for the audio coefficients of each channel according to professional experience, that is, the audio data after downmixing according to the initial debugging downmixing coefficient , which can meet the needs of most users for the expected sound effect, that is, the initial debugging downmix coefficient can be a downmix coefficient with preset sound effects, or a downmix coefficient that still needs to be debugged by users according to their own needs. , when the standard downmixing formula is used to downmix multi-channel audio data, the audio data of the bass channel will be selectively discarded, which makes it difficult for the audio effect presented by the downmixed audio data to meet the user's expectations. After downmixing, it is necessary to increase the bass data stream to reduce the downmix loss. Therefore, the downmixed audio data is the downmixed audio data in which the bass audio data is added.

作为一种示例，步骤S10包括：获取用户输入的音频播放优化指令，根据所述音频播放优化指令获取预设数量的声道的音频数据，将各所述声道的音频数据共同作为待缩混音频数据，获取标准缩混公式中修改后的缩混系数，将所述修改后的缩混系数作为初始调试缩混系数，依据所述初始调试缩混系数的预设缩混公式，对所述待缩混音频数据进行缩混，得到缩混后音频数据，其中，所述预设数量具体可以为1、2或3等等。As an example, step S10 includes: acquiring an audio playback optimization instruction input by a user, acquiring audio data of a preset number of channels according to the audio playback optimization instruction, and using the audio data of each channel as the downmix to be mixed Audio data, obtain the modified downmixing coefficients in the standard downmixing formula, use the modified downmixing coefficients as the initial debugging downmixing coefficients, according to the preset downmixing formula of the initial debugging downmixing coefficients, for the said downmixing coefficients The audio data to be downmixed is downmixed to obtain the downmixed audio data, wherein the preset number may specifically be 1, 2, or 3, and so on.
