quality opus_demo vs opusenc
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 -cvb...

[opus-tools] [PATCH] Add channel-mapping argument to force channel mapping
This patch adds a new option "channel-mapping" to opusenc which sets the channel mapping family used by the multistream encoder. Please let me know whether adding this option is worthwhile and whether the help string is okay. I tried to keep it short but accurate. The error message for an unimplemented channel mapping is "Error cannot create encoder...

quality opus_demo vs opusenc
Hi, I am interested in this part of the answer: "Make sure both are also linked to the same libopus (opusenc could be using the system libopus 1.0.x while opus_demo is from git)" I dowloaded a tarball distrib of libopus (1.1-beta),build and installed it,and afterwards did the same with opus-tools (0.1.7),using the former installed libopus library (also using libogg 1.3.1). When I execute opus-demo it...

opusenc equivalent of lame presets
Are there comparable presets or recommendations for opusenc vbr parameters? lame --preset standard --> opusenc ??? lame --preset extreme --> opusenc ??? I have used opusenc without custom vbr parameters and the files were much smaller than for lame's standard preset but I can't answer if that's comparable or the result was lossier in opu...

Quality difference between opus_demo.exe and opusenc.exe
Hello! I encoded a voice file (48kHz) with opusbin\opusenc.exe with the standard settings and decoded it. The output was amazing. I could not hear any loss at all. Then i encoded the same file with opus_demo.exe and standard settings and then decoded it. The output had a sizzling noise, even when I used full bandwidth. I think I have played around with...

quality opus_demo vs opusenc
I suspect the main difference is due to time alignment of the samples and the exact trimming at the beginning and at the end of the encoded files. I also note that there's a missing "--" in front of "bitrate" and only one "-" instead of two for cvbr in your opusenc command line. Make sure both are also linked to the same libopus (opusenc could be using the system libopus 1.0.x while opus_demo is from git). In the end, the quality should be almost the same, but the files won't be identical due to minor differences in the way the first and last frame are ha...

opusenc -- no track number metadata?
The docs for opusenc at https://mf4.xiph.org/jenkins/view/opus/job/opus-tools/ws/man/opusenc.html don't mention any way to specify the track number metadata. Is there an undocumented way to do this, or this feature not available? Or is the "track number" meant...

runtime reconfiguration of opusenc
...ist. My name is Michael Mehari and i am a researcher at Ghent University mainly on cognitive radio networking. Recently i am working on a demo scenario on self adjustable wireless audio conferencing and i selected opus for the audio encoding and decoding part. specifically the applications (i.e opusenc and opusdec) from opus-tools are what i was looking for. However, i have one problem when using the opusenc application. The input parameters are start time configurable but i was looking for realtime reconfiguration for example changing bitrate on the fly. With in the context of my demo scena...

[PATCH 0/1] opusenc support for WavPack input

Stop opusenc from generating any comments?
The opusenc tool automatically adds metadata - even if you don't specify any. For example, these tags are created by default on my files: ENCODER=opusenc from opus-tools 0.2 ENCODER_OPTIONS=--bitrate 6 --comp 10 --framesize 60 --padding 0 I've tried using `--discard-comments` but that has no effect. I...

opusenc for ambisonics?
Hi Andrew, I suspect that the configure option should be enable-ambisonics (instead of enable_ambisonics), but for each of opus, libopusenc, opusfile and opus-tools git repos (on master branch), when I try "./configure --enable-ambisonics", I get this error message: configure: WARNING: unrecognized options: --enable-ambisonics Thanks for your help.

opusenc confused by Replaygain tags
Hi, I think I might have kind of, sort of found a bug in opusenc. But do correct me if I am worng. :) When converting an FLAC file that contains RG tags written by bs1770gain the resulting opus file has a way, way too high RG value. I am talking >90dB(!). Here is the metaflac output of the flac file: % metaflac --block-number=2 --list bs.1770/test.flac...

opusenc for ambisonics?
Unfortunately, ambisonics aren't exposed in opusenc yet, thus the trouble. They're an API-only feature, but it's a good time to discuss what such a command-line interface would look like, notably: how to specify multiple streams & stream order, select the mapping family, coupled channels, and how to specify the matrix (for family 3). Lik...

A GUI for opusenc.exe - OpusDrop
...scoding files from .wav to .opus more comfortable and faster. It's a small C#-Windows-Application and is described and available for download at [1]. At the moment it's still more in an alpha state, there might be some bugs. So for example one problem is, that I can't shut down the opusenc.exe, if I want to quit the GUI. Don't know why, opusenc just won't shut down. From my point of view it's finished to the point, where it does all the things, I personally need. (Maybe transcoding from .opus to .wav would be handy too). But maybe you guys know, how the code can be t...

opusenc equivalent of lame presets
> No comments? Mostly no. There are no presets because the encoder is smart enough to act intelligently by default. The exposed knobs are exposed only for those who know they actually need them. This is pretty much how Xiph encoders have always been. The programming API is a bit different, because there are more use cases for streaming. Monty
