1.1 Much slower on Raspberry Pi
Christian,
I will give 64kbit/s a try and post the figures. My own project is voice
only and requires low bitrate so was hoping that it was just the way I was
compiling and not an actual regression in speed for SILK. The raspberry PI
is quite a cheap and handy reference platform though the ARM side is fairly
underpowered but has a great GPU. It also has no audio in which is a pain
for playing

Channel Mapping Family for Ambisonics
Hello,
We (Google) have been experimenting with configuration and adjustments to
CELT-only Opus that give good results for compressing ambisonic audio
signals [1]. Based on our results so far, we would like to use Opus to
encode spatial audio. We hope to make it easy/possible to use libopus with
other common tools and software modules (ffmpeg/libav in particular).
Based on my reading of the

FIXED_POINT
I have build celt with FIXED_POINT option (latest 0.6.1 as well as from the
git repo) on windows. However I am not getting a valid output (all samples
are saturated) when I try to decode with this version. The input file was
encoded with the same fixed point version. Does fixed point version work at
all?
Following are the command line settings;

Missing plc.c file
Hi,
I've try to enable the new loss concealment code with celt-0.6.1. I've
run "configure --enable-new-plc" but I've got a missing plc.c file
while compiling. It is also missing for version 0.6.0.
Can you release this missing file?
Thank you,

1.1 Much slower on Raspberry Pi
I have just started trying Opus with a view to using it in a project. I am
interested in embedded hardware and tried it on the Raspberry Pi using the
raspbian distro.
The version of libopus in the repos is 0.9.14. I installed this and tried
encoding 2 minutes of speech from a librevox recording. It managed this at
a respectable pace for complexity 10:

bug reports and missing license headers
Hi all!
What is the right way to report bugs in libopus? I couldn't find any
publicly available bugtracker.
Anyway, the problem I need to report is that some source files in
libopus are missing copyright headers. This breaks license check
script that we use in chromium to validate licenses for third-party
dependencies. Specifically the following files don't have copyright
header:

bug found in CELT 0.6.1, fix proposed.
Hi all I have spent the last three days evaluating CELT on our supported platforms.
I found a bug in quant_bands.c, that due to processor/compilation differences did not cause an issue on x86 platforms, but is a problem on the MIPS processor embedded devices. When decoding on the MIPS devices, there was a lot of noise added during the decoding, the noise is mainly in the 15 khz to 21 khz range.

Blackfin compatibility and licensing
Hi everyone,
I am new in this forum and looking for some answers.
Anyone have successfuly ran CELT on a Blackfin (fixed point) processor?
If so, how much effort was necessary to do this?
What are the main differences betwen CELT and OPUS? OPUS is a fork of
CELT project?
CELT have a formal license file? I plan to use in a comercial product,
it is allowed?
Thank you for your time.

Force Opus/CELT to encode 2 mono instead of 1 stereo
Hi, folks,
I have an old CELT thing that I'm updating to Opus and I'm trying to get
individual pieces upgraded. My first task is upgrading the CELT encoder
to Opus.
The old CELT thing treated the L and R channels as independent mono
streams, encoded them somehow with CELT to form one bitstream, sent one
bitstream across, and then unpacked it manually after the decoder.
Can I do that

llcon software using CELT
Hi all,
I am the developer of the llcon software (llcon.sf.net) which is a
software making it possible for musicians to play in real-time over the
internet. Up to now I have used ADPCM or no audio coding.
Gregory Maxwell was pointing me to the great CELT project. Using CELT
has the advantage to be able to use higher sample rates, getting lower
code rate and better error concealment.

right settings for highest quality

I am trying to evaluate the quality of the CELT codec by using the 0.8.0

how to use celt codec
hey great job with the celt codec. im very eager to use it. im just
wondering how? there is little to no documentation on how to use the celt
codec.
is there anyway to encode an icecast stream using the celt codec? or is
there any software with celt support built in? thanks.

Hi,
This isn't that new anymore, but I'd let everyone know that CELT

release and we fixed many bugs. For this release, Monty has written an
extensive demo page at:

CELT Test case failures
Hi ,
We've downloaded the CELTV0.11.1 source code from celt-codec.org . But
having trouble with mathops-test and tandem-test unit test that
exercises internal components of CELT codec, please find attached
document for each test case failure in details.
Also could you please give some inputs on CELT Low complexity code and
full version of the code, point me source code to CELT
