ASF to FLAC

Upload an ASF video and save its audio track as FLAC. This converter is useful when you need the sound without the video stream.



ASF is a media file format developed by Microsoft. This format is preferred for Windows Media. This player can play not only video or audio files, but also mixed recordings that are compressed using certain codecs and saved in an ASF file. Files of this format also additionally store metadata (including title, author, copyright information). The full original name of the format is Advanced Systems Format. The main goal of Microsoft in developing this format was to provide streaming media playback.

FLAC is a free cross-platform audio codec format created in 2001 by Josh Colson and Xiph.Org. The name of the format is an abbreviation of the English phrase Free Lossless Audio Codec. When compressing a file into the FLAC format, it is 50-60% of the original file without loss of sound quality (especially when working with voice recordings). When unpacking such a file, absolute originality is respected. Since the format is free and open, it is supported by almost any software, it is perfect for archiving files and for regular listening to digital recordings.
