The metadata records the original sampling rate which make it possible

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

What sine sweep exactly? How did you obtain it, and how exactly did you encode and decode it? Jan > The strange > thing was that even though the output wave file was at 48 kHz, it

Hi everyone, I have profiled Opus on AArch64. I just run opus_demo with some pcm files. Following is time proportion of FFT with different bitrate. Bitrate | Time cost by FFT/iFFT 24kb/s | 15% 48kb/s | 15% 96kb/s | 13% Any comment? I want some data close to real application, any suggestion?

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

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

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 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

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

Dear all, When I install the current version of opus-tools on my Ubuntu system, I have the following problem: When I try to open the test vector 'testvector01.bit', I got the error message 'Decoding complete. This doesn't look like a Opus file'. When I open the 'testvector01.bit.opus' the decoding works fine, but the tool opus_compare mentioned, that the number of

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

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

opus_decode() produces 16-bit signed linear PCM, and opus_decode_float() produces 32-bit floating point PCM that is useful when you want a higher bit depth. If you need 8-bit linear PCM then a simple solution would be to use only the top 8 bits of each 16-bit sample from opus_decode(). Note that the WAV format uses unsigned rather than signed integers for 8-bit linear PCM. (It uses signed for

Hi I used opus_demo to clarify how opus works, I try this command: opus_demo -e" audio 8000 1 8000 -cbr /somedirectory/pcm_mono_ochomil.raw /somedirectory/test.opus And I get the file test.opus, then comes the first problem, this file hasn't header so i can't reproduce it using an external tool, how can i add a header to this file Then when i trie to run opus_demo -d 8000 1
