Set up your development environment

Identify software requirements

In this Learning Path, you’ll learn how to convert the Stable Audio Open Small model to the LiteRT (.tflite) format, then build a simple test program to generate audio on a mobile device.

Your first task is to prepare a development environment with the required software:

• Android NDK: version r25b or newer.
• Python: version 3.10 or newer (tested with 3.10).
• CMake: version 3.16.0 or newer (tested with 3.28.1).

Create workspace directory

Create a separate directory for all the dependencies and repositories that this Learning Path uses.

Export the WORKSPACE variable to point to this directory, which you will use in the following steps:

    

        
        
mkdir my-workspace
export WORKSPACE=$PWD/my-workspace

    

Install Python 3.10

Download and install Python version 3.10 using the following commands:

    

        
        

sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt update
sudo apt install python3.10 python3.10-venv python3.10-pip
  

    

    

        
        

brew install python@3.10
brew link python@3.10 --force
  

    

You can verify the installation and check the version with:

    

        
        
python3.10 --version

    

Install CMake

CMake is an open-source tool that automates the build process for software projects, helping to generate platform-specific build configurations.

    

        
        

sudo apt update
sudo apt install cmake
  

    

    

        
        

brew install cmake
  

    

You can verify the installation and check the version with:

    

        
        
cmake --version

    

See the CMake install guide for troubleshooting instructions.

Install Bazel

Bazel is an open-source build tool which you will use to build LiteRT libraries.

    

        
        

cd $WORKSPACE
export BAZEL_VERSION=7.4.1
wget https://github.com/bazelbuild/bazel/releases/download/{$BAZEL_VERSION}/bazel-{$BAZEL_VERSION}-installer-linux-x86_64.sh
sudo bash bazel-7.4.1-installer-linux-x86_64.sh
export PATH="/usr/local/bin:$PATH"
  

    

    

        
        

cd $WORKSPACE
export BAZEL_VERSION=7.4.1
curl -fLO "https://github.com/bazelbuild/bazel/releases/download/{$BAZEL_VERSION}/bazel-{$BAZEL_VERSION}-installer-darwin-arm64.sh"
sudo bash bazel-7.4.1-installer-darwin-arm64.sh
export PATH="/usr/local/bin:$PATH"
  

    

You can verify the installation and check the version with:

    

        
        
bazel --version

    

Install Android NDK

To run the model on Android, install Android Native Development Kit (Android NDK):

    

        
        

cd $WORKSPACE
wget https://dl.google.com/android/repository/android-ndk-r25b-linux.zip
unzip android-ndk-r25b-linux.zip
  

    

    

        
        

cd $WORKSPACE
wget https://dl.google.com/android/repository/android-ndk-r25b-darwin.zip
unzip android-ndk-r25b-darwin.zip
  

    

For easier access and execution of Android NDK tools, add these to the PATH and set the NDK_PATH variable:

    

        
        

export NDK_PATH=$WORKSPACE/android-ndk-r25b/
export ANDROID_NDK_HOME=$NDK_PATH
export PATH=$NDK_PATH/toolchains/llvm/prebuilt/linux-x86_64/bin/:$PATH
  

    

    

        
        

export NDK_PATH=$WORKSPACE/android-ndk-r25b/
export ANDROID_NDK_HOME=$NDK_PATH
export PATH=$NDK_PATH/toolchains/llvm/prebuilt/darwin-x86_64/bin/:$PATH
  

    

Now that your development environment is ready and all the prerequisites are installed, you can move on to test the Stable Audio Open Small model.
