AudioLDM 是一个开源的音频处理库，它可以用于实现语音识别、语音合成、语音转换等应用。该库提供了一组音频信号处理算法，包括语音信号的预处理、特征提取、噪声抑制、语音增强、声学模型训练等。

项目开源地址：https://github.com/haoheliu/AudioLDM

截止到目前(20230505)，AudioLDM 的几大核心功能

• 文本到音频(Text-to-Audio)：给予文本输入，生成音频
• 音频到音频(Audio-to-Audio)：给定一个音频，生成另一个包含相同类型声音的音频
• 文本指导的音频到音频的风格转换(Text-guided Audio-to-Audio Style Transfer)：使用文本描述将一个音频的声音转移到另一个音频中

首先，使用 conda 创建一个全新的 python 虚拟环境

conda create -n audioldm python=3.8 
conda activate audioldm

库的安装可以直接使用 pip

pip install audioldm

使用之前，我们先准备好模型，其实在命令处理的时候，会自动去下载，但是由于网络和文件太大的问题，经常导致失败。

这里提供了一份，供大家下载

解压后，将文件夹 audioldm 放到 C:\Users\$你的用户名\.cache 下面，没有的文件夹，自己创建

链接：https://pan.quark.cn/s/b85444078028

解压后，同样也是将文件夹 huggingface 放到 C:\Users\$你的用户名\.cache 下面

完成后，就可以直接使用命令行工具 audioldm 来体验体验了

# 根据文本来生成
audioldm -t "A hammer is hitting a wooden surface" 

音频播放器

# 根据声音生成
audioldm --file_path trumpet.wav

音频播放器

#  声音风格迁移
audioldm --mode "transfer" --file_path trumpet.wav -t "Children Singing" 

音频播放器

如果在跑上述命令时出现类似下面的报错

Some weights of the model checkpoint at roberta-base were not used when initializing RobertaModel: ['lm_head.dense.bias', 'lm_head.decoder.weight', 'lm_head.bias', 'lm_head.dense.weight', 'lm_head.layer_norm.weight', 'lm_head.layer_norm.bias']
- This IS expected if you are initializing RobertaModel from the checkpoint of a model trained on another task or with another architecture (e.g. initializing a BertForSequenceClassification model from a BertForPreTraining model).
- This IS NOT expected if you are initializing RobertaModel from the checkpoint of a model that you expect to be exactly identical (initializing a BertForSequenceClassification model from a BertForSequenceClassification model).

这是由于显卡的显存小了，我这里测试了，8G 是跑不了默认的模型，也就是 audioldm-full-l.ckpt。因此，可以更换更小的模型，通过参数 --model_name 来指定

audioldm --model_name audioldm-s-full-v2 -t "A hammer is hitting a wooden surface"

除了可以使用命令行来处理声音，源码中还集成了 (gradio)[https://xugaoxiang.com/2023/04/27/python-web-gradio/] 这个 web 框架，方便大家在网页中操作

git clone https://github.com/haoheliu/AudioLDM
cd AudioLDM
python app.py

对于不懂技术的同学来讲，这个还是非常友好的。

关于中文的使用问题，测试了，发现效果很差。可以来个曲线救国，就是使用翻译软件将中文翻成英文，然后使用。这里推荐一个 chrome 浏览器的插件 deepl，非常好用，插件地址：https://chrome.google.com/webstore/detail/deepl-translate-reading-w/cofdbpoegempjloogbagkncekinflcnj?utm_source=chrome-ntp-icon

解决方法是，降低 urllib3 的版本号

pip install urllib3==1.25.11
