This is the same thing as .aac files, right (what people commonly but erroneously refer to as "Apple Audio Codec")? What is the relationship between this and .m4* (m4a, m4b, m4v), etc.? For the benefit of reviewers, we ask that you post the text of the proposed registration in the body of your e-mail message to this list.

USAC stands for "Unified Speech and Audio Coding", also referred to as Exte= nded High Efficiency Advanced Audio Coding (xHE-AAC). 2.1 Full Name Max Neuendorf 2.2 E-Mail max.neuendorf@iis.fraunhofer.de 2.3 Type Name "audio" 2.4 Subtype Name Standards Tree (no prefix) "usac" 2.5 Required Parameters none 2.6 Optional Parameters none 2.7 Encoding Considerations Binary Files are encoded binary USAC audio packed in the MPEG-4 audio format Low O= verhead Audio Transport Multiplex / Low Overhead Audio Stream (LATM/LOAS) a= s defined in ISO/IEC 14496-3.=20 Files SHALL be transmitted without CR/LF conversion, 7-bit stripping, or an= y other modification to the binary data. Files MAY contain ID3v2.x frames at any LATM/LOAS frame boundary. For use over the Internet, it is assumed that lower layers take care of tra= nsmission errors, so audio/usac data MAY include USAC frames generated with= out the optional cyclic redundancy check (CRC) data. Bit rate not allocated= to CRC data can be allocated to audio data, thus yielding improved audio q= uality. The USAC audio data is binary data, and must be specifically encoded for no= n-binary transport; the Base64 encoding is suitable when attaching to Email= . Note that the MPEG audio data typically does not yield further compressio= n when using file-based lossless compression, e.g. zip. 2.8 Security Considerations USAC is a tagged data format, and some tags are available for private use. = As such, arbitrary material could potentially be transferred in the USAC s= tream, including executable content. Tagged data containing executable cont= ent SHOULD never be sent and MUST not be executed if it is received. Note: The requirement that such content must not be executed on receipt is = especially important since situations exist where content will be generated= independently and therefore could contain executable content that the send= er or receiver is unaware of. It is the responsibility of the decoder/player client to respect and apply = appropriate file security and protection against any potential malicious co= ntent. audio/usac objects are not signed or encrypted internally. External securit= y mechanisms must be employed to ensure content confidentiality and integri= ty. 2.9 Interoperability Considerations The AAC family of codec technologies is specified in ISO/IEC 13818-7 as AAC= LC Profile, in ISO/IEC 14496-3 as AAC, HE-AAC and HE-AAC v2 Profiles, and = in ISO/IEC 23003-3 as xHE-AAC Profile.

With this e-mail I would kindly like to invite experts to review and commen= t on the proposal as recommended in RFC6838, 5.2. We intend to register this mime type in the Standards Tree for types "regis= tered by a recognized standards-related organization". Note that there is a related review request for registration of "audio/aac"= . Any feedback is welcome.

I would have thought that Media Fragments would be applicable here; for example, linking to a particular point in an audio file (rather than just the beginning).

Only=20 printable ASCII characters are allowed in registrations at this time.=20 (It's a pedantic concern, but that's the way it is. RFC 6838/the=20 registration procedure should probably be updated at some point.) As a suggestion/concern, I think that the magic number(s) field should=20 specify the position of those bytes in the byte stream, without=20 reference to structures in the format itself. RFC 6838 says: "Magic=20 numbers are byte sequences that are always present at a given place in=20 the file and thus can be used to identify entities as being of a given=20 media type." Basically the idea is: if you have a random blob of bytes=20 and a media type service (e.g., HTTP, e-mail client) tries to serve it,=20 can the service sniff the content without knowing much of anything about = what it is, and serve it as this media type? So, this field should say=20 where 0x2B7 occurs as an exact offset from the beginning of the content, = or a way to use the first few bytes of the content to figure out the=20 variable offset.
