windows部署spleeter 版本2.4.0：分离音频的人声和背景音乐

一、Spleeter 是什么？

Spleeter 是由法国音乐流媒体公司 Deezer 开发并开源的一款基于深度学习的音频分离工具。它能够将音乐中的不同音轨（如人声、鼓、贝斯、钢琴等）分离为独立的音频文件，适用于音乐制作、学术研究、音频处理等领域。

二、核心功能

1. 多音轨分离：
   • 2stems：分离为 人声（vocals） 和 伴奏（accompaniment）。
   • 4stems：分离为 人声、鼓、贝斯 和 其他。
   • 5stems：分离为 人声、鼓、贝斯、钢琴 和 其他。
2. 高效处理：
   • 支持 CPU 和 GPU（需 TensorFlow GPU 版本）加速。
   • 单曲处理仅需数秒至数分钟（取决于硬件配置）。
3. 开源免费：
   • 代码和预训练模型完全开源（GitHub MIT 协议）。
   • 无需商业授权，适合个人和学术用途。

三、安装过程

github地址: https://github.com/deezer/spleeter/tree/master

1.创建conda虚拟环境  python使用3.9
conda create -n spleeter python=3.9
conda activate spleeter2.安装依赖ffmpeg和libsndfile
conda install ffmpeg libsndfile3.安装最新版spleeter
pip install spleeter4.下载测试文件
wget https://github.com/deezer/spleeter/raw/master/audio_example.mp35.执行
spleeter separate -p spleeter:2stems -o output audio_example.mp3
最后在命令执行路径下生成目录output/audio_example，内部有两个文件，人声音文件vocals.wav和背景音乐文件accompaniment.wav

各种模型下载：2stems、4stems、5stems

四、报错处理

报错处理一：找不到指定的模块mkl_intel_thread.2.dll

(spleeter) C:\Users\81097864\Downloads>spleeter separate -p spleeter:2stems -o output audio_example.mp3
INTEL oneMKL ERROR: 找不到指定的模块。 mkl_intel_thread.2.dll.
Intel oneMKL FATAL ERROR: Cannot load mkl_intel_thread.2.dll.

numpy和mkl的版本不对，卸载后重新安装，安装方式：

解决：建议直接下载numpy-1.24.5+mkl-cp39-cp39-win_amd64.whl下载地址：

https://github.com/cgohlke/numpy-mkl-wheels/releases

(spleeter) C:\Users\81097864\Downloads>pip install numpy-1.23.5+mkl-cp39-cp39-win_amd64.whl

报错处理二：github模型2stems.tar.gz下载失败

(spleeter) C:\Users\81097864\Downloads>spleeter separate -p spleeter:2stems -o output audio_example.mp3

2stems.tar.gz模型文件下载失败。可以手动下载https://github.com/deezer/spleeter/releases/download/v1.4.0/2stems.tar.gz后，解压到spleeter separate命令执行所在的路径下。

我的命令执行路径如下：

(spleeter) C:\Users\81097864\Downloads>spleeter separate -p spleeter:2stems -o output audio_example.mp3

模型位置： 命令执行路径/pretrained_models/2stems

五、Windows用户注意

命令spleeter在 Windows可能上无法正常工作。这是一个已知问题，我们希望很快修复。在命令行中替换spleeter separate为python -m spleeter separate，应该可以正常工作。

六、指定模型文件路径

通过环境变量MODEL_PATH指定模型文件所在位置，2stems、4stems、5stems这些模型文件夹都是MODEL_PATH的子目录

# 指定模型文件所在位置
(spleeter) D:\big-model>set MODEL_PATH=D:\big-model\spleeter-model# 其他参数 
#--verbose：打印日志 
#-c ： 指定输出文件格式
#-o ： 指定结果文件目录
#-f :  指定结果文件名称
(spleeter) D:\big-model>spleeter separate --verbose -p spleeter:2stems -c mp3 -o D:\big-model\audio -f {filename}_{instrument}.{codec} D:\big-model\audio_example.mp3
