Joe Belfiore of Microsoft has once again revealed an info pertaining to Windows 10 for Phones/Small tablets over Twitter which many music fans would appreciate.
As per Joe, Windows 10 for Phones will also get native FLAC support just like its PC counterpart. Support for this format will however not be present in the first preview build which will be unveiled in February but will be added in later months.
About FLAC (via xiph
FLAC stands for Free Lossless Audio Codec, an audio format similar to MP3, but lossless, meaning that audio is compressed in FLAC without any loss in quality. This is similar to how Zip works, except with FLAC you will get much better compression because it is designed specifically for audio, and you can play back compressed FLAC files in your favorite player (or your car or home stereo) just like you would an MP3 file.
FLAC stands out as the fastest and most widely supported lossless audio codec, and the only one that at once is non-proprietary, is unencumbered by patents, has an open-source reference implementation, has a well documented format and API, and has several other independent implementations.
