Advanced Systems Format (ASF) is a proprietary Microsoft product, which serves as a container for Windows multimedia content. Microsoft designed it for streaming and to be independent of systems and protocols. It supports chapters, captions, subtitles, metadata tags, streaming, and hardware players, but does not support menus.

 

How to open an ASF file?

It is best to use Windows Media Player to open an ASF file. Alternatively, VLC media player is a good choice too. Keep in mind that ASF can contain WMA and WMV files, which might display as the file extension of the ASF file.

Free Lossless Audio Codec (FLAC) is a file format that shrinks an audio file’s size, which, as the word “lossless” in the name implies, results in no loss in audio quality or original data. FLAC accomplishes this by using an algorithm that compresses the file to approximately 50 to 70 percent of its original size.

 

How to open a FLAC file?

The default program for opening a FLAC file is VLC media player. Other details about FLAC include that it is unpatented, permits music reproduction, is compatible with Telephony Application Programming Interface (TAPI), and is not subject to digital rights management (DRM).

 

Additionally, codecs that can implement FLAC include FFmpeg, Flake and FLACCL for encoding, and Audiocogs for decoding. Lastly, as the word “free” in the name suggests, FLAC is open-source software.
