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?

opusdec -V opusdec opus-tools f2a2e88 (using libopus unknown) I've got an opus file encoded from a .wav off a cd, 44100Hz: opusinfo 2-24-Overture_in_C_\(In_Memoriam\).opus Processing file "2-24-Overture_in_C_(In_Memoriam).opus"... New logical stream (#1, serial: 38134f1f): type opus Encode...

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 o...

The metadata records the original sampling rate which make it possible to decode t...

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 'test-9ch.opus'. Could you help me for this probelm? Thanks! Here is my command: opusenc test-9ch.wav test-9ch.opus opusdec test-9ch.opus test_9cho...

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 losing the stereo separation. My test file has speech obtained with a Tascam Recorder, and I spoke directly into each mic individually. I can clearly hear the stereo separation in the recorded audio. I...

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...

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 that opusdec can decode by calling libopusfile's decode function. So does the function "opusdec" have...

> To be clear: did you mean the opus output of opusenc > or the wav output of opusdec? I meant during the decoding. There's one significant difference between how Opusdec deals with resampling and how, let's say, MP3 decoders usually deal with resampling. If I make an MP3 at a very low bitrate and if the encoder decides (because it's too low) to internally resample m...

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 be compatible (as long as your command-line options stayed the same, which I assume they will). We would put a GUI in place so that users didn't have to type commands....

...ine, but the tool opus_compare mentioned, that the number of samples are not identical in my decoded file and in the reference decoded file, which I assume to belong to testvector01.bit and not to testvector01.bit.opus. How can I decode the official test vector 'testvector01.bit' with 'opusdec'? Or, how can I convert 'testvector01.bit' to an .opus file, if this is necessary for decoding with 'opusdec'. Thanks in advance for your help. With best regards, Martin -------------- next part -------------- An HTML attachment was scrubbed... URL: http://lists.xiph.org/pip...

...ch mess if I put it all in a single message this time. To be clear, recently I've been testing Opus Tools under Windows and these are my questions/observations. ????#1. To test encoding at low bitrates, I encoded a sine sweep at 12 kbps with Opusenc and then decoded the resulting file with Opusdec. The strange thing was that even though the output wave file was at 48 kHz, it showed clear marks of being resampled from 16 kHz and where my original frequency reached 16 kHz, the frequency in the output file practically fell down to zero. ????Unfortunately, it seems that the lowpass filterin...

What sine sweep exactly? How did you obtain it, and how exactly did you encode and decode it?
