FLAC (Free Lossless Audio Codec)

Changelog This changelog is not exhaustive, review [the git commit log](https://github.com/xiph/flac/commits) for an exhaustive list of changes. ## FLAC 1.4.3 (23-Jun-2023) As there have been additions to the libFLAC interfaces, the libFLAC version number is incremented to 13. The libFLAC++ version number stays at 10. * General * All PowerPC-specific code has been removed, as it turned out those improvements didn't actually improve anything * Large improvements in encoder speed for all presets. The largest change is for the fastest presets and for 24-bit and 32-bit inputs. * Small improvement in decoder speed for BMI2-capable CPUs * Various documentation fixes and cleanups (Mark Grassi, Jake Schmidt) * Various fixes (Ozkan Sezer, Zhipeng Xue, orbea, Sam James, Harish Mahendrakar) * Fix building on Universal Windows Platform (Dmitry Kostjučenko) * flac * A lot of small fixes for bugs found by fuzzing * Various improvements to the --keep-foreign-metadata and --keep-foreign-metadata-if-present options on decoding * The output format (WAV/AIFF/RF64 etc.) is now automatically selected based on what kind of foreign metadata is stored * Decoded file is checked afterwards, to see whether stored foreign format data agrees with FLAC audio properties * AIFF-C sowt data can now be restored * Add --force-legacy-wave-format option, to decode to WAV with WAVEFORMATPCM where WAVE_FORMAT_EXTENSIBLE would be more appropriate * Add --force-aiff-c-none-format and --force-aiff-c-sowt-format to decode to AIFF-C * The storage of WAVEFORMATEXTENSIBLE_CHANNEL_MASK is no longer restricted to known channel orderings * Throw an error when WAV or AIFF files are over 4GiB in length and the --ignore-chunk-sizes option is not set * Warn on testing files when ID3v2 tags are found * Warn when data trails the audio data of a WAV/AIFF/RF64/W64 file * Fix output file not being deleted after error on Windows * Removal of the --sector--align option * metaflac * A lot of small fixes for bugs found by fuzzing * Added options --append and --data-format, which makes it possible to copy metadata blocks from one FLAC file to another * Added option --remove-all-tags-except * Added option --show-all-tags (harridu, Martijn van Beurden) * libFLAC * No longer write seektables to Ogg, even when specifically asked for. Seektables in Ogg are not defined * Add functions FLAC__metadata_object_set_raw and FLAC__metadata_object_get_raw to convert between blob and FLAC__StreamMetadata * Build system * Autoconf (configure) * The option --enable-64-bit-words is now on by default * CMake * The option ENABLE_64_BIT_WORDS is now on by default * Testing/validation * Fuzzers were added for the flac and metaflac command line tools * Fuzzer coverage was improved
