Installation

language

The library is cross-platform and currently supports Linux, macOS, Windows, iOS and Android systems.

Python Package Install

To install the audioFlux package, Python >=3.6, using the released python package.

Using PyPI:

$ pip install audioflux

Using Anaconda:

$ conda install -c tanky25 -c conda-forge audioflux

iOS build

To compile iOS on a Mac, Xcode Command Line Tools must exist in the system:

  • Install the full Xcode package
  • install Xcode Command Line Tools when triggered by a command or run xcode-select command:
$ xcode-select --install

Enter the audioFlux project scripts directory and switch to the current directory, run the following script to build and compile:

$ ./build_iOS.sh

Build and compile successfully, the project build compilation results are in the build folder

Android build

The current system development environment needs to be installed android NDK, ndk version>=16,after installation, set the environment variable ndk path.

For example, ndk installation path is ~/Android/android-ndk-r16b:

$ export NDK_ROOT=~/Android/android-ndk-r16b
$ export PATH=$NDK_ROOT:$PATH

Android audioFlux build uses fftw library to accelerate performance, compile the single-floating point version for android platform. fftw lib successful compilation, copy to audioFlux project scripts/android/fftw3 directory.

Enter the audioFlux project scripts directory and switch to the current directory, run the following script to build and compile:

$ ./build_android.sh

Build and compile successfully, the project build compilation results are in the build folder

Building from source

Linux build

  1. Install compilation dependencies

    # For Ubuntu:
$ sudo apt install cmake clang

# For CentOS:
$ sudo yum install -y cmake clang

  2. Installing MKL lib dependencies on Linux (Optional, Recommended installation)

    You can use this installation document to install MKL

    After installation, you need to set the environment variable MKL_INCLUDE_PATH and MKL_LIB_PATH for MKL.

    For example:

    $ export MKL_INCLUDE_PATH=/opt/intel/oneapi/mkl/latest/include
$ export MKL_LIB_PATH=/opt/intel/oneapi/mkl/latest/lib/intel64

  1. Python setup:

    $ python setup.py build
$ python setup.py install

macOS build

  1. Installing dependencies on macOS

    • Install Command Line Tools for Xcode. Even if you install Xcode from the app store you must configure command-line compilation by running:

      $ xcode-select --install

    • Install llvm.

      $ brew install llvm

$ # After installation, you need to set the environment variable C_COMPILER_PATH and CXX_COMPILER_PATH for MKL. For example:
$ export C_COMPILER_PATH=/usr/local/opt/llvm/bin/clang
$ export CXX_COMPILER_PATH=/usr/local/opt/llvm/bin/clang++

  2. Python setup:

    $ python setup.py build
$ python setup.py install

Windows build

Building from source code is currently not supported on Windows; it is recommended to use pip installation.

If you need to build from source, The easiest way to build audioFlux is by cross-compilation on Linux/macOS using MinGW.

$ python setup.py build_py_win
$ python setup.py install
