Audio Separator 🎶

Summary: Easy to use audio stem separation from the command line or as a dependency in your own Python project, using the amazing MDX-Net, VR Arch, Demucs and MDXC models available in UVR by @Anjok07 & @aufr33.

Audio Separator is a Python package that allows you to separate an audio file into various stems, using models trained by @Anjok07 for use with Ultimate Vocal Remover.

The simplest (and probably most used) use case for this package is to separate an audio file into two stems, Instrumental and Vocals, which can be very useful for producing karaoke videos! However, the models available in UVR can separate audio into many more stems, such as Drums, Bass, Piano, and Guitar, and perform other audio processing tasks, such as denoising or removing echo/reverb.

Features

• Separate audio into multiple stems, e.g. instrumental and vocals.
• Supports all common audio formats (WAV, MP3, FLAC, M4A, etc.)
• Ability to inference using a pre-trained model in PTH or ONNX format.
• CLI support for easy use in scripts and batch processing.
• Python API for integration into other projects.

Installation 🛠️

🐳 Docker

If you're able to use docker, you don't actually need to install anything - there are images published on Docker Hub for GPU (CUDA) and CPU inferencing, for both amd64 and arm64 platforms.

You probably want to volume-mount a folder containing whatever file you want to separate, which can then also be used as the output folder.

For instance, if your current directory has the file input.wav, you could execute audio-separator as shown below (see usage section for more details):

docker run -it -v `pwd`:/workdir beveradb/audio-separator input.wav

If you're using a machine with a GPU, you'll want to use the GPU specific image and pass in the GPU device to the container, like this:

docker run -it --gpus all -v `pwd`:/workdir beveradb/audio-separator:gpu input.wav

If the GPU isn't being detected, make sure your docker runtime environment is passing through the GPU correctly - there are various guides online to help with that.

🎮 Nvidia GPU with CUDA or 🧪 Google Colab

Supported CUDA Versions: 11.8 and 12.2

💬 If successfully configured, you should see this log message when running audio-separator --env_info: ONNXruntime has CUDAExecutionProvider available, enabling acceleration

Conda:

conda install pytorch=*=*cuda* onnxruntime=*=*cuda* audio-separator -c pytorch -c conda-forge

Pip:

pip install "audio-separator[gpu]"

Docker:

beveradb/audio-separator:gpu

 Apple Silicon, macOS Sonoma+ with M1 or newer CPU (CoreML acceleration)

💬 If successfully configured, you should see this log message when running audio-separator --env_info: ONNXruntime has CoreMLExecutionProvider available, enabling acceleration

Pip:

pip install "audio-separator[cpu]"

🐢 No hardware acceleration, CPU only

Conda:

🎥 FFmpeg dependency

💬 To test if audio-separator has been successfully configured to use FFmpeg, run audio-separator --env_info. The log will show FFmpeg installed.

If you installed audio-separator using conda or docker, FFmpeg should already be available in your environment.

You may need to separately install FFmpeg. It should be easy to install on most platforms, e.g.:

🐧 Debian/Ubuntu:

apt-get update; apt-get install -y ffmpeg

 macOS:

brew update; brew install ffmpeg

GPU / CUDA specific installation steps with Pip

In theory, all you should need to do to get audio-separator working with a GPU is install it with the [gpu] extra as above.

However, sometimes getting both PyTorch and ONNX Runtime working with CUDA support can be a bit tricky so it may not work that easily.

You may need to reinstall both packages directly, allowing pip to calculate the right versions for your platform, for example:

• pip uninstall torch onnxruntime
• pip cache purge
• pip install --force-reinstall torch torchvision torchaudio
• pip install --force-reinstall onnxruntime-gpu

I generally recommend installing the latest version of PyTorch for your environment using the command recommended by the wizard here: https://pytorch.org/get-started/locally/

Multiple CUDA library versions may be needed

Depending on your CUDA version and environment, you may need to install specific version(s) of CUDA libraries for ONNX Runtime to use your GPU.

🧪 Google Colab, for example, now uses CUDA 12 by default, but ONNX Runtime still needs CUDA 11 libraries to work.

If you see the error Failed to load library or cannot open shared object file when you run audio-separator, this is likely the issue.

You can install the CUDA 11 libraries alongside CUDA 12 like so:

apt update; apt install nvidia-cuda-toolkit

If you encounter the following messages when running on Google Colab or in another environment:

[E:onnxruntime:Default, provider_bridge_ort.cc:1862 TryGetProviderInfo_CUDA] /onnxruntime_src/onnxruntime/core/session/provider_bridge_ort.cc:1539 onnxruntime::Provider& onnxruntime::ProviderLibrary::Get() [ONNXRuntimeError] : 1 : FAIL : Failed to load library libonnxruntime_providers_cuda.so with error: libcudnn_adv.so.9: cannot open shared object file: No such file or directory

[W:onnxruntime:Default, onnxruntime_pybind_state.cc:993 CreateExecutionProviderInstance] Failed to create CUDAExecutionProvider. Require cuDNN 9.* and CUDA 12.*. Please install all dependencies as mentioned in the GPU requirements page (https://onnxruntime.ai/docs/execution-providers/CUDA-ExecutionProvider.html#requirements), make sure they're in the PATH, and that your GPU is supported.

You can resolve this by running the following command:

python -m pip install ort-nightly-gpu --index-url=https://aiinfra.pkgs.visualstudio.com/PublicPackages/_packaging/ort-cuda-12-nightly/pypi/simple/

Note: if anyone knows how to make this cleaner so we can support both different platform-specific dependencies for hardware acceleration without a separate installation process for each, please let me know or raise a PR!

Usage 🚀

Command Line Interface (CLI)

You can use Audio Separator via the command line, for example:

audio-separator /path/to/your/input/audio.wav --model_filename UVR-MDX-NET-Inst_HQ_3.onnx

This command will download the specified model file, process the audio.wav input audio and generate two new files in the current directory, one containing vocals and one containing instrumental.

Note: You do not need to download any files yourself - audio-separator does that automatically for you!

To see a list of supported models, run audio-separator --list_models

Any file listed in the list models output can be specified (with file extension) with the model_filename parameter (e.g. --model_filename UVR_MDXNET_KARA_2.onnx) and it will be automatically downloaded to the --model_file_dir (default: /tmp/audio-separator-models/) folder on first usage.

Listing and Filtering Available Models

You can view all available models using the --list_models (or -l) flag:

audio-separator --list_models

The output shows a table with the following columns:

• Model Filename: The filename to use with --model_filename
• Arch: The model architecture (MDX, MDXC, Demucs, etc.)
• Output Stems (SDR): The stems this model can separate, with Signal-to-Distortion Ratio scores where available
• Friendly Name: A human-readable name describing the model

Filtering Models

You can filter and sort the model list by stem type using --list_filter. For example, to find models that can separate drums:

audio-separator -l --list_filter=drums

Example output:

-----------------------------------------------------------------------------------------------------------------------------------
Model Filename        Arch    Output Stems (SDR)                                            Friendly Name
-----------------------------------------------------------------------------------------------------------------------------------
htdemucs_ft.yaml      Demucs  vocals (10.8), drums (10.1), bass (11.9), other               Demucs v4: htdemucs_ft
hdemucs_mmi.yaml      Demucs  vocals (10.3), drums (9.7), bass (12.0), other                Demucs v4: hdemucs_mmi
htdemucs.yaml         Demucs  vocals (10.0), drums (9.4), bass (11.3), other                Demucs v4: htdemucs
htdemucs_6s.yaml      Demucs  vocals (9.7), drums (8.5), bass (10.0), guitar, piano, other  Demucs v4: htdemucs_6s

Limiting Results

You can limit the number of results shown using --list_limit. This is useful for finding the best performing models for a particular stem. For example, to see the top 5 vocal separation models:

audio-separator -l --list_filter=vocals --list_limit=5

Example output:

--------------------------------------------------------------------------------------------------------------------------------------------------------------
Model Filename                             Arch  Output Stems (SDR)                   Friendly Name

As a Dependency in a Python Project

You can use Audio Separator in your own Python project. Here's a minimal example using the default two stem (Instrumental and Vocals) model:

from audio_separator.separator import Separator

# Initialize the Separator class (with optional configuration properties, below)
separator = Separator()

# Load a machine learning model (if unspecified, defaults to 'model_mel_band_roformer_ep_3005_sdr_11.4360.ckpt')
separator.load_model()

# Perform the separation on specific audio files without reloading the model
output_files = separator.separate('audio1.wav')

print(f"Separation complete! Output file(s): {' '.join(output_files)}")

Batch processing and processing with multiple models

You can process multiple files without reloading the model to save time and memory.

You only need to load a model when choosing or changing models. See example below:

from audio_separator.separator import Separator

# Initialize the Separator with other configuration properties, below
separator = Separator()

# Load a model
separator.load_model(model_filename='UVR-MDX-NET-Inst_HQ_3.onnx')

# Separate multiple audio files without reloading the model
output_file_paths_1 = separator.separate('audio1.wav')
output_file_paths_2 = separator.separate('audio2.wav')
output_file_paths_3 = separator.separate('audio3.wav')

# Load a different model
separator.load_model(model_filename='UVR_MDXNET_KARA_2.onnx')

# Separate the same files with the new model
output_file_paths_4 = separator.separate('audio1.wav')
output_file_paths_5 = separator.separate('audio2.wav')
output_file_paths_6 = separator.separate('audio3.wav')

Renaming Stems

You can rename the output files by specifying the desired names. For example:

output_names = {
    "Vocals": "vocals_output",
    "Instrumental": "instrumental_output",
}
output_files = separator.separate('audio1.wav', output_names)

In this case, the output file names will be: vocals_output.wav and instrumental_output.wav.

You can also rename specific stems:

• To rename the Vocals stem:

  output_names = {
      "Vocals": "vocals_output",
  }
  output_files = separator.separate('audio1.wav', output_names)

  The output files will be named: vocals_output.wav and audio1_(Instrumental)_model_mel_band_roformer_ep_3005_sdr_11.wav

• To rename the Instrumental stem:

  output_names = {
      "Instrumental": "instrumental_output",
  }
  output_files = separator.separate('audio1.wav', output_names)

  The output files will be named: audio1_(Vocals)_model_mel_band_roformer_ep_3005_sdr_11.wav and instrumental_output.wav

• List of stems for Demucs models:
  • htdemucs_6s.yaml

    output_names = {
        "Vocals": "vocals_output",
        "Drums": "drums_output",
        "Bass": "bass_output",
        "Other": "other_output",
        "Guitar": "guitar_output",
        "Piano": "piano_output",
    }

  • Other Demucs models

    output_names = {
        "Vocals": "vocals_output",
        "Drums": "drums_output",
        "Bass": "bass_output",
        "Other": "other_output",
    }

Developing Locally

This project uses Poetry for dependency management and packaging. Follow these steps to setup a local development environment:

Prerequisites

• Make sure you have Python 3.10 or newer installed on your machine.
• Install Conda (I recommend Miniforge: Miniforge GitHub) to manage your Python virtual environments

Clone the Repository

Clone the repository to your local machine:

git clone https://github.com/YOUR_USERNAME/audio-separator.git
cd audio-separator

Replace YOUR_USERNAME with your GitHub username if you've forked the repository, or use the main repository URL if you have the permissions.

Create and activate the Conda Environment

To create and activate the conda environment, use the following commands:

conda env create
conda activate audio-separator-dev

Install Dependencies

Once you're inside the conda env, run the following command to install the project dependencies:

poetry install

Install extra dependencies depending if you're running with GPU or CPU.

poetry install --extras "cpu"

or

poetry install --extras "gpu"

Running the Command-Line Interface Locally

You can run the CLI command directly within the virtual environment. For example:

audio-separator path/to/your/audio-file.wav

Deactivate the Virtual Environment

Once you are done with your development work, you can exit the virtual environment by simply typing:

conda deactivate

Building the Package

To build the package for distribution, use the following command:

poetry build

This will generate the distribution packages in the dist directory - but for now only @beveradb will be able to publish to PyPI.

How to Use in Colab

1. Link Input:

• video_url: This input is where you paste the URL of the audio or video you want to download. It can be from various platforms supported by yt-dlp. For a full list of supported websites, refer to this link.

• Example:

  https://www.youtube.com/watch?v=exampleID 
  

2. Input Audio File for Separation:

• input: This is the file path of the audio you want to separate. After downloading the audio file, you will need to specify this path to continue with separation.

• Example:

  /content/ytdl/your_downloaded_audio.wav 
  

3. Output Directory:

   • output: This is the path where the separated files will be saved. It defaults to /content/output but can be changed to another directory if desired.

   • Example:

     /content/custom_output 
     

Contributing 🤝

Contributions are very much welcome! Please fork the repository and submit a pull request with your changes, and I'll try to review, merge and publish promptly!

• This project is 100% open-source and free for anyone to use and modify as they wish.
• If the maintenance workload for this repo somehow becomes too much for me I'll ask for volunteers to share maintainership of the repo, though I don't think that is very likely
• Development and support for the MDX-Net separation models is part of the main UVR project, this repo is just a CLI/Python package wrapper to simplify running those models programmatically. So, if you want to try and improve the actual models, please get involved in the UVR project and look for guidance there!
