What is a AVI file?
Audio Video Interleave (AVI) is Microsoft’s venerable multimedia container introduced with Video for Windows. It stores audio and video streams in interleaved RIFF chunks, allowing simple players to read sequentially from disk. While it supports multiple codecs, it lacks modern features like B‑frame timestamping and embedded subtitles. Released in 1992 to counter Apple’s QuickTime, AVI became ubiquitous on Windows 95 thanks to the Indeo and Cinepak codecs. The rise of DivX in 1999 rejuvenated AVI for internet sharing, but mismatched VBR audio led to sync headaches. Microsoft replaced it with ASF/WMV and eventually MP4, yet legacy camcorders and CCTV systems still output AVI.
What is a M4A file?
.m4a is the generic extension for audio‑only MP4 files. Inside, you will typically find AAC or ALAC streams plus metadata for chapters, cover art, and lyrics. The format provides gapless playback, efficient compression, and wide ecosystem support. Apple coined .m4a in 2001 to distinguish music downloads from copy‑protected .m4p tracks sold on the iTunes Store. Because MP4’s audio profiles required no licence fees, many podcasters and game developers adopted .m4a for better quality than MP3 at the same bit‑rate. Today .m4a is recognised by Android, Windows, and most car infotainment systems.

Frequently Asked Questions
How to open a AVI file?
Windows Media Player, VLC, and MPC‑HC open most AVI files. If the clip uses an obscure four‑character codec (FourCC), install the corresponding VFW decoder or remux to MKV with FFmpeg. Adobe Premiere Pro and DaVinci Resolve import AVI but may transcode on the timeline for GPU effects.
How to open a M4A file?
Play .m4a files in iTunes/Music, Groove, or any Bluetooth speaker that accepts AAC. DAWs like Logic Pro and Audition decode on import. If an older device refuses the extension, simply rename to .mp4 both refer to the same container.
