similar to: Reg Fixed point Speex Narrow Band decoding

Hi, I am getting the same problem of divided by zero while decoding in the function multicomb(). I am using fixed point speex code. Can anybody please tell me the solution for it. -----Original Message----- From: speex-dev-bounces@xiph.org [mailto:speex-dev-bounces@xiph.org] On Behalf Of speex-dev-request@xiph.org Sent: Tuesday, March 13, 2007 12:30 AM To: speex-dev@xiph.org Subject: Speex-dev

Hi,all I do some work on ARM cpu with VS2005, speex1.2beta. I use the FIXED_POINT define and it works well of codec and decode. but the speex_preprocess() still cannot work real time. I look into the soucecode , and didn't find any fix-point #ifdef computation . So I wish there should be some fix in the future version. If you already done the similar, pls tell me , thanks! Fan

Hi, In fixed point speex code there is no where satuartions checks are used. The basic arithmetic operations like ADD,ADD32,SUB,MUL etc. are just directly implemented without the saturation checks. Can u please comment on this. For the speex decoder testing, is there any standard streams? if yes from where can i get those? Thaking you all, Yours, Jyothiprakash Reddy, T

Hi, I've encoded the GSM AMR narrow band stream "T01.pcm" using narrow band speex encoder at 24.6kbps. When I try to decode this file using the fixed point speex decoder, it is giving Divided by Zero error in the function multicomb(). Can anybody encountered these type of problems earlier?? if yes, what should be done as rectification?? Thanks & Regards, T. Jyothiprakash

Hi, Can you please share the standard document of Speex codec. I have the api doc and speex manual but it doesnt have the details about the mode of operation and bitrate details etc., So can u please give us those details.

Hello list I'm joining the effort to port speex to a fixed-point version, but as I'm a physicist used to deal only with floating point numbers (lots of them), I have no practice in working with fixed-point versions of such numbers. For instance, in the first source I'm trying to work with, nb_celp.c, it is hard to see that the following two lines of code yield the same

Hi, I am using speex 1.2beta2 on a 24bit DSP that has a severe program and data space limitations. I am only interested in the speex decoder for 11kbps narrowband implementation. I am using the following parameters and structures 160, /*frameSize*/ 40, /*subframeSize*/ 10, /*lpcSize*/ 17, /*pitchStart*/ 144, /*pitchEnd*/ /* 11 kbps medium bit-rate

Hello, I am trying to use speex for speech encoding on my ARM based device. I am facing issues with quality of voice with the narrow band configuration (8k sampling rate). With complexity set to 3 and VBR enabled, I am getting high bitrate output. As an example, My input is 8K stereo and I am passing the encoder with 160 samples at a time as per the manual and samples. When there

I emailed Jean-Marc the arch.h about one week ago, not quite sure whether he actually received that email. Anyway, here I have an improved version of arch.h that I believe that it would be better, to use __int64 only if compiling on eMbedded Visual C++ compiler, so for any other compiler, keep it the same (use long long) ---------------------------------- Chan Kei Yuen (Kenji)

Hi Jean-Marc, Based on the wonderful Speex project, I've created SpeexOutLoud, essentially a Speex codec port for Windows Mobile 2003 devices. I've included a sample project intended to show the usage of SpeexOutLoud codec in a Pocket PC application based on .NET Compact Framework. I'd request you to please go through the attached build, and include it as a contribution to the

I've never tried Speex on a 24-bit DSP, but I would suggest actually leaving the code (nearly) as-is. The scaling factors actually should not change because I'm using integer multiplications, not fractional multiplications. So what should happen is that the top 8 bits or 24-bit values and the top 16-bit of 48-bit values will be unused (filled with sign bits). There may be a few cases where

1，you say “libopusenc depends only on libopus.”but 2，so，i add speexdsp source code ， but 3，so，i 。。。 but now，what can i do。i use libopus 1.2 and 1.2beta and 1.1.3 test -------------- next part -------------- An HTML attachment was scrubbed...

Hi folks, we've tried contacting Jean-Marc Valin but email address bounces. We published yesterday an advisory about libfishsound, you can find it at the following URL: http://www.ocert.org/advisories/ocert-2008-2.html The issues seems to affect Speex (since the code is the same) versions <= 1.1.12. While the 1.2beta branch is not vulnerable we advise that you fix with a security release

I am still getting an error compiling the 1.2-Beta version. The tarball works fine, but I have never been able to compile the 1.2beta from CVS. I have been compiling CVS-HEAD on the machine for quite some time. It goes into this loop: if cmp -s include/asterisk/version.h.tmp include/asterisk/version.h ; then echo; else \ mv include/asterisk/version.h.tmp include/asterisk/version.h ; \

Hi, I'm announcing two new releases of opus, along with the first release of the new libopusenc library. First for opus, we just fixed a bad bug in the surround encoding code that would cause very bad quality on signals beyond a certain amplitude. Thanks to Franziska Trojahn and others from HfT Leipzig for finding this issue through their listening test[1] (the quality of the two bad files

Hey, I'm up and running fine with 30 Polycom 500s connected to Asterisk 1.2Beta on Cent OS 4.1 with a Digium TE110 connected to a PRI line.

I am trying to build 1.2beta1.

Hello, I was wondering how to get the Ajax.Autocompleter to behave more like Autocompleter.Local where it narrows the drop down as you type. The local autocompleter seems to exhibit this behavior naturally. Am I missing an argument somewhere? Joe _______________________________________________ Rails-spinoffs mailing list

hi, i am a university student and completely new for the video codec technology. we have decided to develop a video codec that is specially focus for narrow bandwidth video streaming (provide video streaming experience for GPRS, etc). so i want to have some idea about how a video codec is related with streaming application...? have there any codec developed for these type of requirement, by
