Introduction 👋

In this Tutorial, we will explore the technical process of using Spleeter, a machine learning workflow for TensorFlow, to separate audio tracks. By following this guide, you will learn how to set up the environment, install the necessary packages, run the Spleeter workflow, choose the appropriate model, separate the audio, and work with the output. Spleeter is a powerful tool that allows you to separate vocals, accompaniments, and other components from mixed audio tracks, making it perfect for remixing, resampling, and other audio manipulation tasks. So let's dive in and get started!

Setting Up the Environment 💻

Before we can begin using Spleeter, we need to set up the necessary environment. We will be using Anaconda, a Python distribution that simplifies Package management and environment creation. Make sure you have Anaconda installed on your system. Once you have Anaconda set up, open the Conda Shell and follow the steps below.

1. Create a new environment by entering the command conda create -name spleeter python=3.6. Replace "spleeter" with your desired environment name.
2. Activate the newly created environment with the command conda activate spleeter.

Installing Required Packages 📦

To use Spleeter, we need to install the required packages. Follow the steps below to install them.

1. Install the Python ffmpeg library by entering the command pip install python-ffmpeg.
2. Install ffmpeg and libsndfile using the Conda package manager. Enter the command conda install -c conda-forge ffmpeg libsndfile.

Running the Spleeter Workflow 🔄

Now that our environment is set up and the required packages are installed, we can move on to running the Spleeter workflow.

1. Obtain an MP3 file of the audio track you want to separate. Place the MP3 file in its own subfolder.
2. Open the Conda Shell and navigate to the folder where the MP3 file is located.
3. Enter the command spleeter separate -o <output_folder_name> <mp3_file_name>. Replace <output_folder_name> with the desired name for the output folder and <mp3_file_name> with the name of the MP3 file.

Choosing the Model 🎶

When running the Spleeter workflow, you have the option to choose the model that determines how the audio will be separated. By default, Spleeter uses a two-stem model, which separates vocals and accompaniments. However, Spleeter offers various models that allow for more specific separation, such as isolating guitar, bass, piano, or human voice. Refer to the Spleeter documentation for more information on selecting the appropriate model.

Separating the Audio 🔊

Once you run the Spleeter workflow, the audio will be separated into individual tracks based on the selected model. The separated audio files will be stored in the specified output folder. These files will include vocals, accompaniments, and any other components specified by the chosen model.

Working with the Output 💡

The separated audio files may contain some artifacts or imperfections due to the nature of the separation algorithm. However, you can still work with the output files and clean them up as needed for your specific project or remix. Spleeter provides a powerful starting point for remixing, resampling, or other audio manipulation tasks.

Conclusion 🎉

In this tutorial, we have explored the process of using Spleeter to separate audio tracks. We learned how to set up the environment, install the necessary packages, run the Spleeter workflow, choose the appropriate model, separate the audio, and work with the output. Spleeter offers a versatile and powerful solution for audio separation tasks, making it a valuable tool for musicians, producers, and audio enthusiasts. Experiment with different models and have fun manipulating your audio tracks with Spleeter!
