similar to: extracting SILK only FIXED POINT code

Thanks a lot for your tips. What I have to done to debug: got the raw wav-file, compressed/decompressed it on my PC and saved OPUS packets as an array. Moved this array to the embedded platform and made sure that the frames decoded from the OPUS packets are the same. However, the high noise level was the same, but it wasn`t caused by OPUS. The problem was with my sound bus between an embedded

Hello everyone. I have a problem with a high level of noise after opus encoding/decoding procedure. If I stream a raw data from the microphone and send it back to the speakers I hear the clear sound (with a small delay). If I encode each frame, decode it and send it back to the speakers I hear a very noisy signal - it is so large, so it is almost impossible to distinguish words in my speech...

The attached patch cleans up Opus's x86 intrinsics configury. It: * Makes ?enable-intrinsics work with clang and other non-GCC compilers * Enables RTCD for the floating-point-mode SSE code in Celt. * Disables use of RTCD in cases where the compiler targets an instruction set by default. * Enables the SSE4.1 Silk optimizations that apply to the common parts of Silk when Opus is built in

Ashutosh- It sounds like you're trying to implement an Opus-like application but you have a very constrained environment. If you just want the Silk portion of the codec, then why not just ignore opus and use the silk codec directly? The old SDK is still available in some places, like here: https://code.google.com/archive/p/bkvoice/downloads (Keep in mind that Opus uses a modified version of

I'm building asterisk 11 beta 2. I've been using silk a lot. I don't see silk listed in menuselect as a codec. But I also don't see an asterisk 11 silk codec on http://downloads.digium.com/pub/telephony/codec_silk. Do we use the asterisk 10 codec_silk.so ? sean

Hi, I stumbled upon mentions of a "SILK" codec last night on skypes "skype for sip" information page. I tried looking into it further and found some blog and mailing list posts from 2009 but I can't find any mentions of anything other than skype using the codec. Has the codec not gotten anywhere so far? http://en.wikipedia.org/wiki/SILK

Is there a configuration or compile flag that lets me disable the SILK portion of the codec and use CELT only? I could have sworn that there is something, but I can't seem to find it in the mailing list archives. The application here is that I am attempting to update from the old CELT codec to OPUS. Unfortunately, the CELT codec was running *very* close to the CPU (MIPS32--80MHz) limit

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 Jean-Marc, gdb out is "Program terminated with signal 8, Arithmetic exception." most likely this division by zero. you're right, this crash is reproduce on seq number 4294967265 (20ms rtp packet). This is about 994 days. "Jean-Marc Valin" <jmvalin at jmvalin.ca> писал(а):Hi Dmitry, > >So it's not explicitly in your report, but it looks like the crash

Hello all, after FOMS I decided to take a look at the opus library and I found that I could improve a bit the build system and cleanup the code a little bit. Most of the changes to the code has been suggested by my two tools cowstats and missingstatic (part of the ruby-elf gem if you care). HTH, Diego

Yes those instructions exist, although they're a bit slower than the basic 16x16->32 with 32-bit accumulation (SMLABB). So I'd be surprised if the function with 64 bit accumulation would run as fast as the current code. Don't know how much we care about 16-bit platforms. And accuracy should not matter. On the other hand, a 64-bit implementation is much cleaner/shorter, which is

For a few reasons: There is a missing bit of functionality that is important to me. I know WHAT I want to fox, but I do not know HOW. Also, if I am understanding how this module operates, I have ideas for other modules that use the same base methods. So, I am looking for either the folks that wrote this module or someone who can help me understand it enough for me to make some enhancements to
