The Opus codec is designed for interactive speech and audio transmission over
the Internet. It is designed by the IETF Codec Working Group and incorporates
technology from Skype's SILK codec and Xiph.Org's CELT codec.
It is intended to suit a wide range of interactive audio applications,
including Voice over IP, videoconferencing, in-game chat, and even remote live
music performances.  It can scale from low bit-rate narrowband speech to very
high quality stereo music. The current features are:
Bit-rates from 6 kb/s 510 kb/s
Sampling rates from 8 to 48 kHz
Frame sizes from 2.5 ms to 60 ms
Support for both constant bit-rate (CBR) and variable bit-rate (VBR)
Audio bandwidth from narrowband to full-band
Support for speech and music
Support for mono and stereo
Support for up to 255 channels (multistream frames)
Dynamically adjustable bitrate, audio bandwidth, and frame size
Good loss robustness and packet loss concealment (PLC)
Floating point and fixed-point implementation
This package provides the Opus runtime library.

opus (0.9.14+20120615-1+nmu1) unstable; urgency=medium
* Non-maintainer upload.
* Fix cve-2013-0899: integer overflow in src/opus_decoder.c (closes: #704870).
2012-06-15 - Ron Lee <>
opus (0.9.14+20120615-1) unstable; urgency=low
* Add extern "C" protection to opus_multistream.h.
* Warn about unused returns and NULL arguments for functions where that would
always be an error in the calling code.
* Clearly mark fixed point builds in the internal versioning.
* Better documentation.
* Suggest opus-tools.
2012-05-23 - Ron Lee <>
opus (0.9.14+20120521-2) unstable; urgency=low
* Build the fixed point version for arm(el) and mips(el).
Fixes the unit test timeout seen on the mips buildd.
* Add some extra 'hardening' flags to those upstream uses already.
2012-05-21 - Ron Lee <>
opus (0.9.14+20120521-1) unstable; urgency=low
* Opus draft-14 release testing.
* This one's for Sid.  Closes: #610980
2011-11-02 - Ron Lee <>
opus (0.9.8-1) experimental; urgency=low
* Opus draft-10 release testing.
2011-04-30 - Ron Lee <>
opus (0.9.4-1) experimental; urgency=low
* Initial (re)release as Opus.  Closes: #610980
2010-01-20 - Ron Lee <>
celt (0.7.1-1) unstable; urgency=low
* The "correlation does not imply causation" release.
To celebrate the first release of celt that is actually compatible with a
a previously distributed version, we've renamed the library!
* libcelt is now libcelt0.  The intent from upstream being to make it clear
that one of the above was an accident, and unlikely to be repeated soon.
On the bright side, this means we should be getting proper soname bumps
from now on when the code ABI changes.  The bitstream format still remains
entirely fluid though, applications which communicate with a peer _must_
check that the formats are compatible at runtime.  It may, and indeed is
very likely to, continue changing with every release.
* By some small miracle, this should be an entirely painless transition
though.  The new package doesn't conflict with the existing one, and all
rdeps except mumble will switch to the new package with a binNMU, but not
be broken in the meantime.  They use the .pc file provided, and have been
build tested.  The mumble package is waiting on this one before it can work
properly anyway, so a fix for that is just waiting for this to get through
the NEW queue first now.
* The new PLC is reported to be working Really Well.
2009-11-07 - Ron Lee <>
celt (0.7.0-1) unstable; urgency=low
* Another day, another bitstream format.  Closes: #554559
* Drop the IETF drafts for now.  Better to leave worrying about the
paperwork for this until we have some documents that aren't actually
supposed to expire in less than the life of a distro release.
Closes: #538990 for now.  If you really need to reference them, then
you should probably be tracking git anyhow, as they should be changing
while the codec evolves too.
2009-07-26 - Ron Lee <>
celt (0.6.1-1) unstable; urgency=low
* New upstream release.  Closes: #511163
2008-07-26 - Ron Lee <>
celt (0.4.0-1) unstable; urgency=low
* New upstream release.
