Summary: The document is very well-written and clear. It is ready for
publication, I just found a few nits.

Major issues: None.

Minor issues:

Section 8.8:
When discussing URIs in absolute or relative form, please consider citing RFC

Nits/editorial comments:

Section 4.4:

"If indeed most residual samples are close to zero and a suitable Rice
parameter is chosen, this form of coding, a so-called variable-length code,
fewer less bits to store than storing the residual in unencoded form." "fewer
less bits" -> "uses fewer bits"?

Section 6:

"If a frame header refers to the streaminfo metadata block, the file is not
'streamable', see Section 7 for details. In this way, the file is streamable
and the frame header size small for all of the most common forms of audio
data." What does "In this way" refer to here? In the second sentence, "the
file" does not refer to the same file as in the first sentence, or does it?
Please consider rephrasing this part to make it clearer what is being said.
