size to the stream.
NOTE: MPEG audio was not designed as a file format but as a format
for transmitting audio streams. As such, it does not have any well
defined way of including meta data along with audio information.
Some products embed meta data using zero amplitude frames or
disguised as transmission errors. Others embed the MPEG data in WAV
format.
NOTE: The audio/MPS mime type is in use in addition to the
audio/mpeg. The MPA [RFC 1890] sub-type refers to MPEG audio when it
is segmented and send as a Realtime Transport Protocol (RTP) payload.
2. Registration Information
To: Subject: Registration of MIME media type
audio/mpeg
MIME media type name: audio
MIME subtype name: mpeg
Required parameters: none
Optional parameters: none
Encoding considerations:
For use over internet it is assumed that lower layers take care
of transmission errors, so audio/mpeg data MAY include MPEG
frames generated without the optional cyclic redundancy checks
(CRC) for improved audio quality.
The MPEG audio data is binary data, and must be encoded for
non-binary transport; the Base64 encoding is suitable for Email.
Note that the MPEG audio data does not compress easily using
lossless compression.
Security considerations:
MPEG is a tagged data format, and some tags are available for
private use. As such, arbitrary material could potentially
be transferred in the MPEG stream, including executable content.
Tagged data containing executable content SHOULD never be sent
and MUST not be executed if it is received.
