I may be a bit behind, since I haven't looked at the latest documentation in CVS. My apologies if these problems have already been solved. I think having a default file name is a good idea, but it should be just a default. There should also be a '-o' option to specify the output file name. This option would only apply if there is one input. '-o' should also accept a

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 opus. Hearing tests of course show no

> 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

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.

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

While significantly larger, Opus had produced significant ghost noise (much less than Vorbis did)... I experience the "same" low level noise even in a wav file, even on

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

The problem is the sound output is inversed. What should be heard on the right is heard on the left side and vice versa. So ... if a guard is on your left and he says something you hear him from you right side... This applies to all sounds not just chatter.. bonfires, horse, etc... Is there any way to fix this?

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,

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

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

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

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
