Software Update: FLAC 1.3.1

After a year and a half of silence, a new version of the Free Lossless Audio Codec, or FLAC, has appeared. This sound file format stores data without losing any information, as is the case with mp3, Ogg Vorbis and Opus, for example. FLAC is available for various operating systems and usually requires an external program to serve as a user interface. In Windows, for example, this is possible with ExactAudioCopy and foobar2000. Although a long time has passed, the changelog shows no major changes.
