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 FLV file?
Flash Video (FLV) is a container that encapsulates Sorenson Spark, VP6, or H.264 video together with MP3/AAC audio and on‑screen data events for ActionScript. It became the backbone of early YouTube and news portals because the small header footprint yields quick progressive playback. Macromedia introduced FLV in 2002 with Flash Player 6, offering the first ubiquitous plug‑in‑based video experience on the Web. After Adobe’s acquisition, FLV evolved to support H.264 in 2007 but began losing ground once HTML5 <video> gained traction. By the end of 2020, Adobe disabled Flash, and most CDNs convert FLV archives to MP4 or HLS.

Frequently Asked Questions
How to open a AAC file?
iTunes, Music (macOS/iOS), VLC, and Windows Media Player all handle AAC natively. Most smartphones and Bluetooth speakers decode AAC as their default streaming codec. In the studio, Logic Pro and Adobe Audition import AAC directly. If an older device refuses the file, convert to MP3 with FFmpeg: `ffmpeg -i input.aac -codec:a libmp3lame -q:a 2 output.mp3`.
How to open a FLV file?
Desktop apps like VLC or MPC‑HC open FLV seamlessly. If you encounter a Spark‑encoded clip, convert using FFmpeg: `ffmpeg ‑i input.flv ‑c:v h264 output.mp4`. Web players no longer stream FLV, so upload sites recommend remuxing to MP4 or WebM.
