Nelly Moser Asao Codec

[Nico Gulden]

Hello everybody,

first of all I want to excuse myself for crossposting. I can't estimate
which mailinglist could be the right one for our concern.

Struktur AG, member of the Linux Solutions Group e.V., wants to announce
an Open Source tender for an implementation of an audio codec compatible
with Nellymoser Asao Codec. Struktur wants to pay 6000 US$ for the
project. Proposals can be sent to tenders-4x/***@public.gmane.org until October,
31st 2006. Deadline for the project is January, 15th 2007. For
questions, please contact me.

The whole description can be found at
http://www.lisog.org/projekte/supported_projects/bounty-programm/nellymoserasaocodec-bounty.pdf

A description about the whole idea behind the bounty program can be
found at
http://www.lisog.org/projekte/supported_projects/bounty-programm/description-en.


The idea is comparable with the Google Summer of Code. LiSoG wants to
connect skill, ideas and money to support the development of certain
features in Open Source Software.

The Linux Solutions Group e.V. (LiSoG) is an association founded in
March 2005 with the goal to promote linux based business. With its
business orientation and its cross-national approach it has an unique
position in the German-speaking area. Besides global players in the IT
industry the initiative promotes small and medium business companies
that deal with Open Source. Members are amongst others IBM, MySQL,
Fujitsu Siemens Computers, Novell, Red Hat, Collax, Abraxas for IT
providers, Stuttgarter Versicherung, Federal State of Bavaria, Schweizer
Bundesverwaltung and Universities like Linz, Heilbronn, Nürnberg and
Mannheim. Further information can be found at http://www.lisog.org/

This seems like a relevant posting to me, no apologies necessary.

I do ahve one question; does Nellymoser claim any specific patent
portfolio or reading concerning the codec?

I'm not asking about conjecture or speculation, just what Nellymoser
itself may have already claimed.

Thanks,
Monty

Has anyone ever successfully re-implemented a proprietary codec without
reverse engineering or decompiling? Or even with reverse engineering? I
imagine even if you had the exact code, getting the codebooks without
decompiling would be pretty tough.

I admit I'm a little confused here too. One can make progress by

(a) looking at bitstreams
(b) looking at bitstream changes in response to input/output changes
using the proprietary implementation as a black box
(c) getting a separate agency to do the disassembly and write
documentation for you. This is quite difficult these days as most
EULAs forbid this.

From the contract tender it's not clear which of these methods is

considered acceptable.
