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.
What is a WAV file?
WAV is Microsoft and IBM’s RIFF‑based wrapper for PCM or ADPCM audio. It stores data in little‑endian ‘fmt ’ and ‘data’ chunks, making parsing trivial and ensuring universal DAW support. Introduced in 1991 alongside Windows 3.1’s Multimedia Extensions, WAV replaced raw VOC and AU formats. Its 4 GiB limit was a drawback until RF64 and W64 extensions arrived, but for most pop songs the cap is moot.
