Why convert AMR to FLAC?
FLAC is lossless, so further editing and re-saving won't reduce quality any more. (It can't restore detail that AMR compression already removed.)
FLAC is best for hi-fi music collections, archiving CDs and lossless streaming. Supported by Android, iOS 11+, Windows 10+, macOS, most hi-fi players and browsers.
Will I lose quality?
Converting AMR to FLAC keeps all the quality that is in your AMR file - nothing more is lost. However, it cannot recover detail removed when the AMR was originally created, and the FLAC file will be larger.
