Audio and video

mp3 wav m4a aiff bwf 3gpp, and video played in place

Audio plays in place, and structure mode walks the container it came in — the MPEG frames of an mp3, the chunks of a wav, the boxes of an m4a — each one with its offset, its bitrate and its size. It answers what a player never shows: how the file is actually put together.

Video plays in place, streamed by range requests from the object rather than downloaded whole first.
