+
A run-off of encoded audio frames with no container wrapped around them. That's why two AMR files can usually be joined by simply putting one after the other, and equally why everything beyond the audio itself - a length, a search index, cover art - has to be bolted on as a convention rather than being part of the format, so a player often has to read the whole file to work out how long it is. It's about the simplest thing that can be called an audio file, which is exactly why it appears inside other containers more often than on its own.
