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.
MP4 (MPEG‑4 Part 14) is the dominant container for online video. Based on QuickTime atoms, it can hold H.264/AVC, HEVC, AV1, AAC, AC‑3, timed text, and fragmented segments for adaptive streaming. Finalised in 2001 and revised in 2003 (ISO/IEC 14496‑14), MP4 became the hand‑off format of choice thanks to the iPod Video and PlayStation Portable. The arrival of HLS and DASH further entrenched MP4, which supports ‘moov’ boxes at either head or tail for progressive download or live streams.

Every OS previews WAV Windows Explorer shows waveforms, macOS Finder plays with a space bar tap. In the studio, Pro Tools, Cubase, and Reaper treat WAV as the default recording target. Because it stores linear PCM, transcoding is lossless.
Virtually every player from Safari and Chrome to Xbox and Roku handles MP4. When editing, DaVinci Resolve and Final Cut Pro will optimise H.264 to intraframe proxies for smoother scrubbing. HandBrake transcodes old codecs like DivX to modern H.264+AAC MP4 profiles.
