Why convert ASF to FLAC?
ASF is a Microsoft Advanced Systems Format video container used by Windows media applications and streaming systems. Converting it to FLAC creates a lossless compressed audio format that retains the decoded audio data, ready for workflows that use the destination format.
FLAC plays in current Windows, Android, Linux, VLC, and many music apps; some Apple workflows prefer ALAC.
