一种可选的实施方式中，分别将人声和伴奏输入段落识别模型，以获取人声的人声片段和伴奏的伴奏片段。其中，段落识别模型用于识别音频的目标片段。具体的，将人声输入段落识别模型，以获取人声的目标片段。将伴奏输入段落识别模型，以获取伴奏的目标片段。目标片段可以是音频的副歌片段、高潮片段或者其他片段，例如目标片段为一首歌曲中的重复片段。
可选的，段落识别模型可采用深度学习模型训练得到，本实施例对深度学习模型的结构不作限定。该实施方式通过训练模型实现对人声片段和伴奏片段的智能化提取，可提升音频处理效率和准确率。
可选的，段落识别模型的训练过程包括：获取训练数据集，训练数据集包括多个音频样本以及每个音频样本的标注信息，标注信息用于指示音频样本对应的目标片段。将训练数据集中的多个音频样本分别作为段落识别模型的输入，将训练数据集中的每个音频样本的标注信息作为段落识别模型的输出，对段落识别模型进行训练，直至段落识别模型的损失函数收敛时，停止对段落识别模型的训练，获取训练好的段落识别模型的模型参数。
本实施例中，段落识别模型可用于分析输入音频的节奏和响度变化等信息，可识别出音频的前奏、主歌、副歌、间奏、桥段、尾奏、静音等片段，提取出最有可能的副歌部分，即高潮部分。具体的，提取出不同片段的开始和结束时间戳，进行后续的剪裁，最终输出音频的目标片段。
一种可选的实施方式中，响应于针对第一界面上的第四控件的触控操作，在第二界面显示人声和伴奏的音轨；响应于针对人声的音轨的剪辑操作，获取人声片段；响应于针对伴奏的音轨的剪辑操作，获取伴奏片段。
本实施方式是通过用户在界面剪辑片段的方式获取人声和伴奏的目标片段，用于后续音频混合，该方式增加用户对导入人声和伴奏的自定义处理，可提升用户音频制作的参与度，满足不同用户的音频制作需求。
本实施例的一个可选实施例中，对人声和伴奏进行混合，以获取目标音频，包括：获取人声的第一节奏以及伴奏的第二节奏，对人声的第一节奏和伴奏的第二节奏进行节奏对齐，基于对对齐后的人声和伴奏进行混合，以获取目标音频。
一种可选的实施方式中，以人声的第一节奏为基准，调节伴奏的第二节奏，以使得人声的第一节奏和伴奏的第二节奏一致。
一种可选的实施方式中，以伴奏的第二节奏为基准，调节人声的第一节奏，以使得人声的第一节奏和伴奏的第二节奏一致。
本实施例的一个可选实施例中，对人声和伴奏进行混合，以获取目标音频，包括：对人声的人声片段和伴奏的伴奏片段进行混合，以获取目标音频。具体的，获取人声片段的第一节奏以及伴奏片段的第二节奏，对人声片段的第一节奏和伴奏片段的第二节奏进行节奏对齐，基于对对齐后的人声片段和伴奏片段进行混合，以获取目标音频。
一种可选的实施方式中，以人声片段的第一节奏为基准，调节伴奏片段的第二节奏，以使得人声片段的第一节奏和伴奏片段的第二节奏一致。
一种可选的实施方式中，以伴奏片段的第二节奏为基准，调节人声片段的第一节奏，以使得人声片段的第一节奏和伴奏片段的第二节奏一致。
基于上述节奏对齐的几种实施方式，可知：
通过获取第三音频的第一节奏以及第四音频的第二节奏；对第三音频的第一节奏和第四音频的第二节奏进行节奏对齐；基于对齐后的第三音频和第四音频，获取目标音频。具体的，以第三音频的第一节奏为基准，调节第四音频的第二节奏，以使得第三音频与第四音频节奏一致。
其中，第三音频可以是人声和伴奏中的一个音频，相应的，第四音频可以是人声和伴奏 中的另一音频。或者，第三音频可以是人声片段和伴奏片段中的一个音频，第四音频可以是人声片段和伴奏片段中的另一音频。
需要指出的是，上述实施例涉及对音频或音频片段的节奏检测，节奏检测用于检测节拍中的重拍时间，推测出整个音频或音频片段的速度。对音频节奏的调节包括对音频节奏的拉伸或压缩，通常情况下，将人声轨道的节奏对齐到伴奏轨道，通过音频拉伸或压缩来处理人声轨道文件。
通过对两段音频或两段音频的片段进行节奏检测和对齐，使得混合后的目标音频中的人声和伴奏较好地融合，提升音频处理效果。
