What is a AAC file?
AAC (Advanced Audio Coding) is a lossy audio format designed as the successor to MP3. It delivers better sound quality at similar or lower bitrates and is the default format for Apple devices, YouTube, and most streaming platforms. AAC files typically use the .aac or .m4a extension.
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.
