libsndfile is a C library for reading and writing files containing sampled audio data.

The canonical source code repository for libsndfile is at https://github.com/erikd/libsndfile/.

You can grab the source code using:

$ git clone git://github.com/erikd/libsndfile.git

For building for Android see BuildingForAndroid.

There are currently two build systems; the official GNU autotool based one and a more limited and experimental CMake based build system. Use of the CMake build system is documented below.

Setting up a build environment for libsndfile on Debian or Ubuntu is as simple as:

sudo apt install autoconf autogen automake build-essential libasound2-dev \
    libflac-dev libogg-dev libtool libvorbis-dev pkg-config python

For other Linux distributions or any of the *BSDs, the setup should be similar although the package install tools and package names may be slightly different.

Similarly on Mac OS X, assuming brew is already installed:

brew install autoconf autogen automake flac libogg libtool libvorbis pkg-config

Once the build environment has been set up, building and testing libsndfile is as simple as:

$ ./autogen.sh
$ ./configure --enable-werror
$ make
$ make check

The CMake build system is still experimental and probably only works on linux because it still relies on GNU autotools for bootstrapping. Using it as simple as:

$ Scripts/cmake-build.sh

I would be happy to accept patches to make the CMake build system more portable.

See CONTRIBUTING.md for details.
