Good Morning; Iam asking whether any one have knowledge about is it possiple to incorporate a psycoacoustic model?(specifically?I mean ?MPEG-1 psychoacoustic model 1) into the CELT codec(any version even older versions of the coder,?no matter) Iam using version 0.3.2. Kind Regards; Osama. -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hello, ? I don?t know whether this is the right place to discuss such a question here. I?m sorry. ? I want to evaluate the CELT codec using a known MATLAB implementation of the PEAQ software. If anyone has used this test program he could see that one of the input parameters (3rd one) shifts the frames for both the reference and the under test audio signals. Another parameter (4th one) marks the

Hello everyone, I would like to access the raw CELT encoded bytes by using the command line interface but I am having some difficulties. I do not know how to unpack the Ogg Vorbis wrapper and the STDOUT option just filled my command line with ASCI characters. Anyone have luck dumping the bytes to a text file? Also inputting them back to the celtdec function would be helpful information. Thanks,

Hi Jean-Marc, Thank you. Yes, we do need both channels independent. So, if we encode each channel separately, we will be sacrificing the compression ratio we would achieve with stereo encoding, correct? So, based on what you say here is my understanding. Please confirm this is correct or not: 1) If we use fec, we can reduce cross-talk but increasing bitrate. However, that should result in

Hi, One other question I was wondering about. Is the reason that we hear the crosstalk with fec and packet loss percentage>0 is that Opus uses information from the left channel to try to error correct the right channel and vice versa? I am trying to understand the origin of the crosstalk. Thanks. -Jon > On Jan 27, 2017, at 12:29 PM, Jon Lederman <jon at soniccloud.com> wrote: >

Thanks to Jean-Marc and Tim explaining 'git rebase -i' to me, I've factored my reorganization of the Opus Intrinsics configury into a number of hopefully more comprehensible (and thus more reviewable) pieces. This applies to the current tip of Opus Master in git. Viswanath's Ne10 changes require some slight modification to apply on top of these patches, but nothing major.

Hello opus-dev, Can we please have review on RFCv2? We have quite a few optimizations (Eg: ifft/mdct_backwards, fixed point fft/ifft mdct_forward/backward etc) that are in my pipeline that depend on this patch series being accepted.

I too would like to know the status of the opus IP holders. From what I've seen on the CELT and opus lists, it seems that the CELT part of opus is covered by patents from Xiph and Broadcom, and the SILK part of opus is covered by the rest. All of the IP holders except Qualcomm and Huawei have released their patents to the public as far as opus is concerned, and the general consensus from

Hi, Seems like it's not linking with libm. I suspect it has to do with linking statically with libopus.a (is that intended?). Maybe opus-tools relies on the fact that libopus is linked with libm and doesn't explicitly add it? Greg?

The patch prevents KEIL MDK compile warnings, like:   warning:  #1035-d: single-precision operand implicitly converted to double-precision Actually ARM Cortex-M4F has only a *single precision* (float) FPU. It's suit for all platforms. See the comment at the begin of patch file. Sincerely Forrest Zhang -------------- next part -------------- Specify the floating point constant with single

Stereo makes two assumptions: 1) It assumes the two channels are somehow correlated 2) It assumes the two channels are meant to be

I?m trying to build Opus (git master) for iOS, and it doesn?t build unless I disable the ARM assembly. It looks like the problem is that Apple?s assembler doesn?t support all the assembler directives that the GNU assembler does. I suspect this is a combination of the fact that Apple platforms are Mach-O rather than Elf, and just the fact that Apple?s assembler is extremely divergent from the

I saw the custom API, but nothing explicitly says "CELT-only" just "custom sample rate and frame size". I'll dig further now that you've pointed me in a direction.

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

Hi everyone, I've made several posts recently about CELT being "replaced" by the Opus codec ( http://opus-codec.org/ ) and I thought it was time to give an update on what's going on. As many of you know, I've been involved at the IETF on this new Opus codec, which essentially merge (a modified version of) Skype's SILK codec with CELT. This is more than just two codecs

Is there any consensus on what's the correct fix here?
