Software-update: FLAC 1.4.3

Versie 1.4.3 van de Free Lossless Audio Codec, oftewel FLAC, is verschenen. Dit geluidsbestandsformaat slaat data op zonder dat hierbij informatie verloren gaat, zoals dat wel het geval is bij bijvoorbeeld mp3, Ogg Vorbis en Opus. FLAC is beschikbaar voor diverse besturingssystemen en heeft meestal een extern programma nodig, dat als gebruikersinterface dient. In Windows kan dat bijvoorbeeld met ExactAudioCopy en foobar2000. De changelog voor deze uitgave laat de volgende veranderingen en verbeteringen zien:

A lot of small fixes for bugs found by fuzzingVarious improvements to the –keep-foreign-metadata and –keep-foreign-metadata-if-present options on decodingThe output format (WAV/AIFF/RF64 etc.) is now automatically selected based on what kind of foreign metadata is storedDecoded file is checked afterwards, to see whether stored foreign format data agrees with FLAC audio propertiesAIFF-C sowt data can now be restoredAdd –force-legacy-wave-format option, to decode to WAV with WAVEFORMATPCM where WAVE_FORMAT_EXTENSIBLE would be more appropriateAdd –force-aiff-c-none-format and –force-aiff-c-sowt-format to decode to AIFF-CThe storage of WAVEFORMATEXTENSIBLE_CHANNEL_MASK is no longer restricted to known channel orderingsThrow an error when WAV or AIFF files are over 4GiB in length and the –ignore-chunk-sizes option is not setWarn on testing files when ID3v2 tags are foundWarn when data trails the audio data of a WAV/AIFF/RF64/W64 fileFix output file not being deleted after error on WindowsRemoval of the –sector–align option

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
