About FLV and M4A
FLV: FLV is the Flash Video format that powered early YouTube. Flash is gone, so FLV files usually need converting to play today.
M4A: M4A is an MPEG-4 container holding AAC audio. It sounds better than MP3 at the same size and is the default format for iPhone voice memos, Apple Music downloads and many Android recorders.
