前言:
如今兄弟们对“814c语言程序设计”可能比较关怀,小伙伴们都需要学习一些“814c语言程序设计”的相关内容。那么小编在网络上网罗了一些有关“814c语言程序设计””的相关内容,希望看官们能喜欢,咱们快快来学习一下吧!懂乐理的音乐专业人士可以通过写乐谱并通过乐器演奏来展示他们的音乐创意和构思,但不识谱的素人如果也想跨界玩儿音乐,那么门槛儿就有点高了。但随着人工智能技术的快速迭代,现在任何一个人都可以成为“创作型歌手”,即自主创作并且让AI进行演唱,极大地降低了音乐制作的门槛。
本次我们基于PaddleHub和Diffsinger实现音频歌声合成操作,魔改歌曲《学猫叫》。
配置PaddleHub
首先确保本地就已经安装好了百度的PaddlePaddle深度学习框架,随后输入命令安装PaddleHub库:
pip install paddlehub@2.4.0
PaddleHub是基于PaddlePaddle生态下的预训练模型,旨在为开发者提供丰富的、高质量的、直接可用的预训练模型,也就是说语音模型我们不需要单独训练,直接使用paddlehub提供的模型进行推理即可,注意这里版本为最新的2.4.0。
安装成功之后,配置环境变量:
由于PaddleHub会把音色模型下载到本地,如果不配置环境变量,默认会下载到系统的C盘,所以这里单独设置为E盘。
随后需要将Win11的cmd编码设置为utf-8:
首先找到设置页面搜索地区,并点击更改国家或地区选择管理语言设置选择更改系统区域设置勾选Beta版: 使用Unicode UTF-8 提供全球语言支持,重启生效。
如果不设置utf-8编码,PaddleHub会因为乱码问题报错。
接着安装diffsinger:
hub install diffsinger
随后在终端运行代码:
import paddlehub as hubmodule = hub.Module(name="diffsinger")
这里指定diffsinger的模型库,程序返回:

说明PaddleHub已经配置好了,执行过程中预训练模型会被下载到E盘。
Diffsinger模型推理
DiffSinger是一个基于扩散概率模型的 SVS 声学模型,一个参数化的马尔科夫链,它可以根据乐谱的条件,迭代地将噪声转换为旋律谱。
推理之前,安装推理加速模块:
pip install onnxruntime
通过隐式优化变异约束,DiffSinger 可以被稳定地训练并产生真实的输出。
这里通过内置的singing_voice_synthesis方法:
singing_voice_synthesis(inputs: Dict[str, str],sample_num: int = 1,save_audio: bool = True,save_dir: str = 'outputs')
参数含义是:
1. inputs (Dict[str, str]): 输入歌词数据。2. sample_num (int): 生成音频的数量。3. save_audio (bool): 是否保存音频文件。4.save_dir (str): 保存处理结果的文件目录。
在官方文档中:
作者给出了一段示例代码:
results = module.singing_voice_synthesis( inputs={ 'text': '小酒窝长睫毛AP是你最美的记号', 'notes': 'C#4/Db4 | F#4/Gb4 | G#4/Ab4 | A#4/Bb4 F#4/Gb4 | F#4/Gb4 C#4/Db4 | C#4/Db4 | rest | C#4/Db4 | A#4/Bb4 | G#4/Ab4 | A#4/Bb4 | G#4/Ab4 | F4 | C#4/Db4', 'notes_duration': '0.407140 | 0.376190 | 0.242180 | 0.509550 0.183420 | 0.315400 0.235020 | 0.361660 | 0.223070 | 0.377270 | 0.340550 | 0.299620 | 0.344510 | 0.283770 | 0.323390 | 0.360340', 'input_type': 'word' }, sample_num=1, save_audio=True, save_dir='outputs')# text:歌词文本# notes:音名# notes_duration:音符时值(时长)# input_type:输入类型(文本)
示例中使用的是林俊杰的歌曲《小酒窝》。
这里,最核心的逻辑是inputs的notes参数,也就是乐谱中的音名,而notes_duration参数则是该音名的持续时长。

说白了,就是按照简谱的键位转换为音名。
以旋律相对简单的《学猫叫》为例子:
C’ D’ E’ G C’ E’ E’ D’ C’D’ G’ G’G’ G’ C’ B C’ C’ C’ C’ C’ B C’ B C’ B A G我们一起学猫叫 一起喵喵喵喵喵 在你面前撒个娇 哎呦喵喵喵喵喵 F C Dm GG G A A A A A G E G E G D’ C’ G E’ E’ E’ F’ G’ C’ C’ E’ D’我的心脏砰砰跳 迷恋上你的坏笑 你不说爱我 我就喵喵喵
它的前七个音符分别对应CDEGCEE,对应代码:
results = module.singing_voice_synthesis( inputs={ 'text': '我们一起学猫叫', 'notes': 'D#3 | E3 | E5 | G4 | C5 | E5 | E5', 'notes_duration': '0.407140 | 0.307140 | 0.307140 | 0.307140 | 0.307140 | 0.307140 | 0.307140 ' , 'input_type': 'word' }, sample_num=1, save_audio=True, save_dir='./outputs')
这里推理的音频存储在outputs文件夹内。
结语
利用DiffSinger我们可以简单的将歌词和旋律通过代码转换为实体歌声,但需要注意的是该项目只是输出了清唱部分,真正的音乐作品还需要添加伴奏以及调音等操作,欲知后事如何,且听下回分解,另外,魔改版本的《学猫叫》已经上传到Youtube(B站):刘悦的技术博客,欢迎品鉴。
