similar to: runtime reconfiguration of opusenc

Hi Opus list, Please forgive me if this has been asked before. I find that Opus encoder created in mode OPUS_APPLICATION_AUDIO (as opposed to _VOIP) is using a lot of bits to encode silent periods of speech. This is relevant to a voip application for which good quality music is desirable, and in which I add a minimal comfort noise (order of few bits loud, e.g. MLS signal of amplitude 1 or 2)

Hi Hope this is the correct forum for my questions. I have 3 x m9000''s and 2 x m5000''s, Which I would like to use ZFS root/boot disks with support for Dynamic Reconfiguration. Sun SPARC Enterprise M8000/M9000 Servers Product Notes for XCP Version 1040 reports this issue as being broken.

Hello everyone, I have the following scenario: * 2 host machines (H1 and H2) running VMs. I execute migrations (QEMU) from one host to the other, and so on. The migrations are done in a dedicated LAN (eth1 in both hosts) while regular department LAN runs on eth0 * 1 computer (my desktop computer) also connected to this common LAN on eth0. The VMs have a Python script sending UDP packets to

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.

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

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 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

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

This is intended to measure the cpu performance of the encoder. The float is the number of seconds of audio data processed divided by the number of real-time seconds since encoding

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.

Hello list members, If I encode a CD quality (44.1kHz @ 16 bits) wav file with the "opusenc" tool using the "--speech" option (optimize for speech according to the documentation), what would be the sampling rate of the resulting file? The encoder tells me the bit-rate of the encoded file, but it says nothing about the sampling rate. Does the tool use the Full-Band option or

Well, with stored music files, with close to transparency bitrate, you don't really need Opus. Now compare it with Vorbis when streaming on a low bandwidth connection with real-time latency... 2015-10-25 2:01 GMT-02:00 Christoph Anton Mitterer <calestyo at scientia.net>: > Hey. > > I just wondered,... which is the recommended bitrate and further > settings of opusenc (like

Everything above 96kbps on that table is speculative, as the highest multi-participant listening testing done was at 96kbps. Here's the results from that test, if you're curious: http://listening-test.coresv.net/results.htm As you can see, at that rate Opus ranged from slightly perceptible to imperceptible. Also importantly, note how few of the donors were able to give significant
