Category:FLAC audio files

FLAC (Free Lossless Audio Codec) is an open-source format for lossless compression of digital audio. A raw audio source such as PCM or WAV can typically be compressed to 50-60% of its original size.

FLAC files are not accepted at Commons Archive because it is possible to upload them to Wikimedia Commons by re-encoding them as Ogg FLAC (a FLAC stream wrapped in an OGG container). This can be done with the official command-line FLAC tool as follows:

flac --best --ogg -o name_flac.ogg name.flac

Ogg FLAC files over 100 MB are accepted temporarily while seeking a filesize exemption on Wikimedia Commons.
