[[#comment]]

*RFC 2046 4.3.  Audio Media Type
>A media type of "audio" indicates that the body contains audio data.
Although there is not yet a consensus on an "ideal" audio format for
use with computers, there is a pressing need for a format capable of
providing interoperable behavior.

[1] "audio" の媒体型は本文が音声データで構成されることを示します。
計算機で使う「理想」の音声形式の合意はまだありませんが、相互通信可能な振舞いを提供する能力のある形式への強い需要があります。

>The initial subtype of "basic" is specified to meet this requirement
by providing an absolutely minimal lowest common denominator audio
format.  It is expected that richer formats for higher quality and/or
lower bandwidth audio will be defined by a later document.

[2] 初期亜型 "basic" は、絶対最小公分母音声形式を提供することでこの要件を満たすように規定します。
後々の文書で高品質とか低帯域の音声用のより裕福な形式が定義されることが期待されます。

>The content of the "audio/basic" subtype is single channel audio
encoded using 8bit ISDN mu-law [PCM] at a sample rate of 8000 Hz.

"audio/basic" 亜型は、8ビット [[ISDN]] mu-law を使って例えば
8000Hz の歩合で符号化された単一チャンネル音声です。

[INS[
訳注: ''mu-law'' はなんと訳すのでしょうか>
- [4] そのままで良いのでは?
[[#comment]]
]INS]

>Unrecognized subtypes of "audio" should at a miniumum be treated as
"application/octet-stream".  Implementations may optionally elect to
pass subtypes of "audio" that they do not specifically recognize to a
robust general-purpose audio playing application, if such an
application is available.

認識出来ない "audio" の亜型は、少なくても
"application/octet-stream" として取り扱うのが良いです。
実装者は具体的に認識出来ない "audio" 
の亜型を、頑強な一般目的音声演奏応用があれば、そいつに渡すことを任意で選んでも構いません。

で標準化するぞーという意思が垣間見られます。
