Requirements
While aubio can be built without any external dependencies, we recommend to use at least some of the following libraries.
Platform notes
On all platforms, you will need to have installed:
- a compiler (gcc, clang, msvc, ...)
- python (any version >= 2.7, including 3.x)
- a terminal to run command lines in
Linux
The following External libraries will be used if found: libav, libsamplerate, libsndfile, libfftw3.
macOS
The following system frameworks will be used on Mac OS X systems:
- Accelerate to compute FFTs and other vectorized operations optimally.
- CoreAudio and AudioToolbox to decode audio from files and network streams.
Note
To build a fat binary for both i386 and x86_64, use ./waf configure --enable-fat.
The following External libraries will also be checked: libav, libsamplerate, libsndfile, libfftw3.
Windows
To use a specific version of the compiler, --msvc_version. To build for a specific architecture, use --msvc_target. For instance, to build aubio for x86 using msvc 12.0, use:
waf configure --msvc_version='msvc 12.0' --msvc_target='x86'
The following External libraries will be used if found: libav, libsamplerate, libsndfile, libfftw3.
iOS
The following system frameworks will be used on iOS and iOS Simulator.
- Accelerate to compute FFTs and other vectorized operations optimally.
- CoreAudio and AudioToolbox to decode audio from files and network streams.
To build aubio for iOS, configure with --with-target-platform=ios. For the iOS Simulator, use --with-target-platform=iosimulator instead.
By default, aubio is built with the following flags on iOS:
CFLAGS="-fembed-bitcode -arch arm64 -arch armv7 -arch armv7s -miphoneos-version-min=6.1"
and on iOS Simulator:
CFLAGS="-arch i386 -arch x86_64 -mios-simulator-version-min=6.1"
Set CFLAGS and LINKFLAGS to change these default values, or edit wscript directly.
Build options
Some additional options can be passed to the configure step. For the complete list of options, run:
$ ./waf configure --help
Double precision
To compile aubio in double precision mode, configure with --enable-double.
To compile aubio in single precision mode, use --disable-double (default).
Fat binary
To build a fat binary on Mac OS platforms, configure with --enable-fat.
External libraries
External libraries are checked for using pkg-config. Set the PKG_CONFIG_PATH environment variable if you have them installed in an unusual location.
Note
If pkg-config is not found in PATH, the configure step will succeed, but none of the external libraries will be used.
libav
libav.org, open source audio and video processing tools.
If all of the following libraries are found, they will be used to compile aubio_source_avcodec. so that aubio_source will be able to decode audio from all formats supported by libav.
- libavcodec
- libavformat
- libavutil
- libavresample
To enable this option, configure with --enable-avcodec. The build will then failed if the required libraries are not found. To disable this option, configure with --disable-avcodec
libsndfile
libsndfile, a C library for reading and writing sampled sound files.
With libsndfile built in, aubio_source_sndfile will be built in and used by aubio_source.
To enable this option, configure with --enable-sndfile. The build will then fail if the required library is not found. To disable this option, configure with --disable-sndfile
libsamplerate
libsamplerate, a sample rate converter for audio.
With libsamplerate built in, aubio_source_sndfile will support resampling, and aubio_resample will be fully functional.
To enable this option, configure with --enable-samplerate. The build will then fail if the required library is not found. To disable this option, configure with --disable-samplerate
libfftw3
FFTW, a C subroutine for computing the discrete Fourier transform
With libfftw3 built in, aubio_fft will use FFTW to compute Fast Fourier Transform (FFT), allowing aubio to compute FFT on length that are not a power of 2.
To enable this option, configure with --enable-fftw3. The build will then fail if the required library is not found. To disable this option, configure with --disable-fftw3
External tools
If the following tools are found, additional documentations are built:
doxygen to build the API documentation.
txt2man to build the :ref:`manpages`
These tools are searched for in the current PATH environment variable. By default, the documentation is built only if the tools are found.
To disable the documentation, configure with --disable-docs. To build with the documentation, configure with --enable-docs.
