similar to: opus testvectors

I downloaded test vectors from opus-codec.org site. The site indicated that the test files are intended for verifying that the Opus decoders are operating properly. I assume I could also use them to verify my encoder implementation, right? For example, use testvector01.dec as input to my encoder and compare its output bitstream with the corresponding testvector01.bit bitstream file. Any idea

Hi, Dear alls I had encounted a problem in using opus-tool-0.2-opus-1.3(download from www.opus-codec.org, Win64 binaries: opus-tools-0.2-win64.zip). First, I use opusenc to generate a opus file which input is a 9-channels wav file. The opusenc can work. Then, I use opusdec to transform the generated opus file to wav file, but opusdec can't work. I received the error message: failed to open

Hi I'm having a problem compiling opus-tools-0.1.7. Version opus-tools-0.1.6 seems to compile OK. I've tried with opus-1.0.3 and opus-1.1-beta. The errors are like this:- "undefined reference to `sqrtf'" etc. This OS is Peppermint Three, similar to Ubuntu 12.04. It uses:- gcc --version gcc (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3 Google says it's maybe something to do

Hi, I am looking at the conformance test using opus_compare and the test vectors and I am a bit confused about FEC. Is there a way to validate that a decoder processes LBRR frames correctly? Thanks, Alexis

Hi I am an Audacity (http://audacity.sourceforge.net/) developer and I'd like to see Audacity reading and writing Opus files as easily as it does others. What would you recommend as a way forward for this? I am thinking that (Win) we should ship opusenc.exe and opusdec.exe and send command line stuff to them; that way we wouldn't need to dip into your code and as you update we would

Hi, I had found a Opus TODO list in https://wiki.xiph.org/index.php?title=OpusTodo&mobileaction=toggle_view_desktop . The item "Opus-tools" interest me. And here is my question about "Port opusdec to libopusfile/libopusurl": 1. Does this function have achieved? On one hand, I think not literally. On the other hand, after briefly reviewing opusdec.c of opus-tools, I found

Hello, I've been using Opus on an STM32 M4 platform for speech coding in mono mode. I thought I'd try stereo for grins to see if I can handle the CPU load, and I'm getting a return code of -1 from opus_decode_float (using CBR and 40ms frames). I decided to try the opusenc and opusdec tools to just see how the command line apps would behave. I am getting decoded audio, but I am

Dear all, is the program opus_compare capable of comparing each decoder output or is it only capable of comparing the decoded testvectors? Or in other words: Can I use the opus_compare for comparing the decoder output when I have encoded and decoded arbitrary speech files?

Hi, I've been using the command line opusenc/opusdec tools for a while now to encode/decode files. The next version of OS X changes a few things, so I was looking to recompile these tools using a version of the OS X SDK > 10.7 (needed for apple's "hardened runtime") but had no luck. How can I compile a static version of opus tools on OS X that doesn't depend on any other

Hi, I have found differences in quality between opus_demo and opusenc/opusdec. I used for both applications the same raw pcm file,16 bit,48khz,litle endian. i use libopus 1.1-beta and opus-tools-0.1.7. The command for opus_demo is: opus_demo audio 48000 1 64000 -cvbr -framesize 10 in.pcm out.pcm For opusenc/dec: opusenc --raw --raw-chan 1 bitrate 64 -cvbr --framesize 10 in.pcm in.opus

using iTunes i've noticed that AAC is very good at re-encoding own lossy sound. let's test Opus! neroaacenc.exe -q 0.75 -if 000.wav -of 001.m4a neroaacdec.exe -if 001.m4a -of aac001.wav wavdiff.exe 000.wav aac001.wav Comparing 000.wav - aac001.wav...

Hi, I have downloaded the latest stable version *1.0.2 opus audio codec* from the following link: http://www.opus-codec.org/downloads/ *Details of OS & CPU:* OS : Microsoft Windows XP CPU : intel core 2 Duo cpu I am using Microsoft visual C++ 2010 Express to build the codec (opus.vcxproj available in the package downloaded). I am able to build it & could generate the application

Dear authors of Opus, currently, the manpages that come with opus-tools are written in the traditional man(7) markup language. I am proposing to rewrite them into the semantic markup of the mdoc(7) language. I am willing to do the work. Both the man(7) and mdoc(7) languages have been around for decades, and are supported by the prevalent formatters: groff(1) on most Linuxes and mandoc(1) on the

hello all - since i am such a newbie, i thought i would be the ideal person to put together a guide on how i got the opus tools working. ?i am using virtualbox and a new centOS-linux virtual-machine. i chose to use the minimalist centOS iso file so there would be no pre-installed packages. any suggestions or improvements to this guide would be most appreciated. ?? also, wish to express my

Thanks for the answer. I'll take a look at this tool and verify my implementation. But I'd like to clarify the moment. If the following is applied for a test vector Reference Float Point Encoder --> Reference Float Point Decoder --> Float Point Output Reference Fixed Point Encoder --> Reference Float Point Decoder --> Fixed Point Output And then, if Float Point Output and

Hi All, First time poster to this group, please ignore my ignorance? I?m trying to use Opus 1.1 on a 400MHz MIPS 24k CPU (AR9331, specifically, like in the Arduino Yun). I?ve successfully built (I think) opus-1.1 and opus-tools-1.8 and they run, but are dog slow. opus-1.1 does have the ?enable-fixed-point option set, as this chip only has soft-float.
