Assuming the Android Ndk is installed at location `/path/to/toolchain`, building
libsndfile for Android (arm-linux-androideabi) should be as simple as:

Since I (erikd), do almost zero Android development, I am happy accept patches
for this documentation and script to improve its utility for real Android
developers.

## Using CMake
(Tested on Linux)
For convenience, export the following variables:
```
export ANDROID_ABI=arm64-v8a
export ANDROID_PLATFORM_API_LEVEL=29
export NDK_ROOT=/path/to/android/ndk
```
Set `ANDROID_ABI`, `ANDROID_PLATFORM_API_LEVEL` according to your target system. Now cd into the libsndfile root directory, and run
```
cmake -S . -B build -DCMAKE_TOOLCHAIN_FILE=$NDK_ROOT/build/cmake/android.toolchain.cmake -DANDROID_ABI=$ANDROID_ABI -DANDROID_PLATFORM=$ANDROID_PLATFORM_API_LEVEL
```
cd into `build` and run make
```
cd build
make [-j <number of parallel jobs>]
```
This will build libsndfile for android.

# Changelog
All notable changes to this project will be documented in this file.
The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
## [1.2.0] - 2022-12-25
### Fixed
* Searching for LAME dependency with CMake build system (issue #821).
* CMake build from Autotools tarball (issue #816).
* Build on UWP platform (issue #824).
* Fix signed integer overflow (issue #785).
* Skipping large wav chunks on stdin (PR #819).
### Removed
* Maximum samplerate limit, thanks @drmpeg, @justacec (issue #850).
In version 1.1.0, an artificial limit of 655350 Hz was created, but as it
turned out, this is not enough for some scenarios.
## [1.1.0] - 2022-03-27
### Added
* MPEG Encode/Decode Support.
Uses libmpg123 for decode, liblame for encode. Encoding and decoding support
is independent of each other and is split into separate files. MPEG support
is generalized as subformats, `SF_FORMAT_MPEG_LAYER`(I,II,III) so that it
might be used by other containers (`MPEG1WAVEFORMAT` for example), but also
contains a major format `SF_FORMAT_MPEG` for 'mp3 files.'
Encoding Status:
* Layer III encoding
* ID3v1 writing
* ID3v2 writing
* Lame/Xing Tag writing
* Bitrate selection command
* VBR or CBR
Decoding Status:
* Layers I/II/III decoding
* ID3v1 reading
* ID3v2 reading
* Seeking
* New fuzzer for OSS-Fuzz, thanks @DavidKorczynski.
* This `CHANGELOG.md`. All notable changes to this project will be documented in
this file. The old `NEWS` file has been renamed to `NEWS.OLD` and is no longer
updated.
* Add support for decoding MPEG III Audio in WAV files.
* `SECURITY.md` file to give people instructions for reporting security
vulnerabilities, thanks @zidingz.
* Support for [Vcpkg manifest mode](https://vcpkg.readthedocs.io/en/latest/users/manifests/).
If you have problems with manifest mode, disable it with `VCPKG_MANIFEST_MODE`
switch.
* [Export CMake targets from the build tree (PR #802)](https://cmake.org/cmake/help/latest/guide/importing-exporting/index.html#exporting-targets-from-the-build-tree)
* CIFuzz fuzzer, thanks to @AdamKorcz (PR #796)
### Changed
* `SFC_SET_DITHER_ON_READ` and `SFC_SET_DITHER_ON_WRITE` enums comments in
public header, thanks @SmiVan (issue #677).
* `ENABLE_SNDFILE_WINDOWS_PROTOTYPES` define is deprecated and not needed
anymore.
Previously, in order for the [`sf_wchar_open`()](http://libsndfile.github.io/libsndfile/api.html#open)
function to become available on the Windows platform, it was required to
perform certain actions:
```c
#include <windows.h>
#define ENABLE_SNDFILE_WINDOWS_PROTOTYPES 1
#including <sndfile.h>
```
These steps are no longer required and the `sf_wchar_open`() function is
always available on the Windows platform.
* Use UTF-8 as internal path encoding on Windows platform.
This is an internal change to unify and simplify the handling of file paths.
On the Windows platform, the file path is always converted to UTF-8 and
converted to UTF-16 only for calls to WinAPI functions.
The behavior of the functions for opening files on other platforms does not
change.
* Switch to .xz over .bz2 for release tarballs.
* Disable static builds using Autotools by default. If you want static
libraries, pass --enable-static to ./configure
### Fixed
* Typo in `docs/index.md`.
* Typo in `programs/sndfile-convert.c`, thanks @fjl.
* Memory leak in `caf_read_header`(), credit to OSS-Fuzz ([issue 30375](https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=30375)).
* Stack overflow in `guess_file_type`(), thanks @bobsayshilol, credit to
OSS-Fuzz ([issue 29339](https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=29339)).
* Abort in fuzzer, thanks @bobsayshilol, credit to OSS-Fuzz
([issue 26257](https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=26257)).
* Infinite loop in `svx_read_header`(), thanks @bobsayshilol, credit to OSS-Fuzz
([issue 25442](https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=25442)).
* GCC and Clang pedantic warnings, thanks @bobsayshilol.
* Normalisation issue when scaling floating point data to `int` in
`replace_read_f2i`(), thanks @bobsayshilol, (issue #702).
* Missing samples when doing a partial read of Ogg file from index till the end
of file, thanks @arthurt (issue #643).
* sndfile-salvage: Handle files > 4 GB on Windows OS
* Undefined shift in `dyn_get_32bit`(), credit to OSS-Fuzz
([issue 27366](https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=27366)).
* Integer overflow in `nms_adpcm_update`(), credit to OSS-Fuzz
([issue 25522](https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=25522)).
* Integer overflow in `psf_log_printf`(), credit to OSS-Fuzz
([issue 28441](https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=28441)),
([issue 25624](https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=25624)).
* ABI version incompatibility between Autotools and CMake build on Apple
platforms.
Now ABI must be compatible with Autotools builds. Note that this change
requires CMake >= 3.17 for building dylib on Apple platforms.
* Fix build with Autotools + MinGW toolchain on Windows platform.
See https://github.com/msys2/MINGW-packages/issues/5803 for details.
### Security
* Heap buffer overflow in `wavlike_ima_decode_block`(), thanks @bobsayshilol,
credit to OSS-Fuzz ([issue 25530](https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=25530)).
* Heap buffer overflow in `msadpcm_decode_block`(), thanks @bobsayshilol,
credit to OSS-Fuzz ([issue 26803](https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=26803)).
* Heap buffer overflow in `psf_binheader_readf`(), thanks @bobsayshilol,
credit to OSS-Fuzz ([issue 26026](https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=26026)).
* Index out of bounds in `psf_nms_adpcm_decode_block`(), credit to OSS-Fuzz
([issue 25561](https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=25561)).
* Heap buffer overflow in `flac_buffer_copy`(), thanks @yuawn, @bobsayshilol.
* Heap buffer overflow in `copyPredictorTo24`(), thanks @bobsayshilol,
credit to OSS-Fuzz ([issue 27503](https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=27503)).
* Uninitialized variable in `psf_binheader_readf`(), thanks @shao-hua-li,
credit to OSS-Fuzz ([issue 25364](https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=25364)).

* Patches should always be submitted via a either Github "pull request" or a
via emailed patches created using "git format-patch".
* Patches for new features should include tests and documentation.
* Commit messages should follow the ["How to Write a Git Commit Message"](https://chris.beams.io/posts/git-commit/) guide:
1. Separate subject from body with a blank line
2. Limit the subject line to 50 characters
3. Capitalize the subject line
4. Do not end the subject line with a period
5. Use the imperative mood in the subject line
6. Wrap the body at 72 characters
7. Use the body to explain what and why vs. how
Additional rule: the commit message may contain a prefix. The prefix must
contain the name of the feature or source file related to the commit and must
end with a colon followed by the message body.
Examples of good commit messages:
1. Fix typo
2. Update CHANGELOG.md
3. Add ACT file format support
4. ogg_vorbis: Fix granule position when seeking Vorbis streams
Examples of bad commit messages:
1. Fixed bug (rule 5)
2. update docs (rule 3)
3. Add very cool feature. (rule 4)
* Patches to fix bugs should either pass all tests, or modify the tests in some
sane way.
* When a new feature is added for a particular file format and that feature

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 libopus-dev pkg-config python
libflac-dev libogg-dev libtool libvorbis-dev libopus-dev libmp3lame-dev \
libmpg123-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 opus pkg-config
brew install autoconf autogen automake flac libogg libtool libvorbis opus mpg123 pkg-config
Once the build environment has been set up, building and testing libsndfile is
as simple as:

Second advice is about Ogg, Vorbis FLAC and Opus support. Searching external
libraries under Windows is a little bit tricky. The best way is to use
[Vcpkg](https://github.com/Microsoft/vcpkg). You need to install static libogg,
libvorbis, libflac and libopus libraries:
[Vcpkg](https://github.com/Microsoft/vcpkg).
vcpkg install libogg:x64-windows-static libvorbis:x64-windows-static
libflac:x64-windows-static opus:x64-windows-static libogg:x86-windows-static
libvorbis:x86-windows-static libflac:x86-windows-static opus:x86-windows-static
Then and add this parameter to cmake command line:
Install Vcpkg and then add this parameter to cmake command line:
-DCMAKE_TOOLCHAIN_FILE=<path-to-vcpkg>/scripts/buildsystems/vcpkg.cmake
You also need to set `VCPKG_TARGET_TRIPLET` because you use static libraries:
You also need to set `VCPKG_TARGET_TRIPLET` if you want to use static libraries:
-DVCPKG_TARGET_TRIPLET=x64-windows-static
Then you need to install static libogg, libvorbis, libflac, libopus, mpg123 and
mp3lame Vcpkg packages.
After 1.1.0beta2 you don't need to install dependencies manually. Libsndfile
now supports [Vcpkg manifest mode](https://vcpkg.readthedocs.io/en/latest/users/manifests/)
and all dependencies are installed automatically.
However, you can turn off the manifest mode and return to the classic mode using
the `VCPKG_MANIFEST_MODE` parameter from the command line:
-DVCPKG_MANIFEST_MODE=OFF
In classic mode, you need to install the required libraries manually:
vcpkg install libvorbis:x64-windows-static libflac:x64-windows-static
opus:x64-windows-static mp3lame:x86-windows-static mpg123:x86-windows-static
libvorbis:x86-windows-static libflac:x86-windows-static
opus:x86-windows-static mp3lame:x86-windows-static mpg123:x86-windows-static
**Note**: Use must use the same CRT library for external libraries and the
libsndfile library itself. For `*-static` triplets Vcpkg uses
[static CRT](https://vcpkg.readthedocs.io/en/latest/users/triplets/).

# _FORTIFY_SOURCE is already defined, and if not, adds -D_FORTIFY_SOURCE=2

# Newer mingw-w64 msys2 package comes with a bug in
