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

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 -cvbr --framesize 10 in.pcm in.opus

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 any of the settings in opus_demo.exe,

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 to be a "comment" ? More people at Magnatune are downloading our opus files, so this came up... -john

opusenc for ambisonics?
I compiled the latest (git master) of opus, libopusenc, opusfile and opus-tools: $ opusenc --version opusenc opus-tools 0.2-8-g4976421 (using libopus 1.3.1-4-gad8fe90d) I tried to encode a 3rd order Ambisonics wav file with the standard Ambix (ACN-SN3D) format; opusinfo is reporting : Streams: 16, Coupled: 0     Channel Mapping Family: 255 Map: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14,

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). Likewise, there's no multistream support at

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).

A GUI for opusenc.exe - OpusDrop
Hi, I've put some work in a small GUI that makes transcoding 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.

OS X opusenc/opusdec?
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

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.

[PATCH 0/1] opusenc support for WavPack input
This patch to opus-tools adds optional support to WavPack lossless format as input to opusenc. Like support to FLAC, it depends on an external library, libwavpack, and may be disabled on configure.

Help with OpusEnc
Hi all, New to list and Opus Codec. I've been using it on a beagleboneblack with 'arecord'. One of the things I've noticed while encoding is that Opus reports a float with an 'x' along with "realtime". Where can I look up where this calculation is derived? It got me looking and I've noticed that when I record something from a known source (in testing)

About the --speech option in opusenc
Hello, I want information about the behavior of the --speech option in the opusenc program in opus tools package. The documentation only tells that it optimizes for speech, but what does this mean in terms of sampling frequency, bitrate, etc.? Thank you very much.

recommended opus bitrate / opusenc setting for general?
Hey. I just wondered,... which is the recommended bitrate and further settings of opusenc (like complexity and framesize) for general music (e.g. including classical music) to achieve more or less transparency? Talking about CD level audio (16bit; 44,1 kHz; Stereo) The only source I could find regarding that was: http://wiki.hydrogenaud.io/index.php?title=Opus#Music_encoding_quality But that

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

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've tried using `--comment ENCODER=` but that adds a duplicate tag. My limited
