Hi! >From http://www.vorbis.com/stereo.psp : "Oggenc's default choice varies by bitrate and each mode is selectable by the user" So, how am I supposed to do that? E.g. what do I have to do when I want an 128kbps .OGG using lossless stereo, or does this "selectable by the user" mean only that I can choose the stereo mode indirectly by choosing an appropriate bitrate?

This topic is possibly more appropriate on the flac-dev list, since most flac users are not going to be interested in the details of WAVE format errors. Assuming it's ok to keep talking about it here... Ben, you've stumbled upon one of the common shortcomings of specifications. There are often assumptions which are not spelled out, or there are pieces which are vague. In some

Hi, maybe this is of interest for someone out there. I found that taking the difference between an original sample and its decoded Vorbis counterpart is a cool way to mangle sounds (especially voice samples get a nice weird touch :] ). A side effect is that the result is not only exactly what information the encoder omits, it also contains things that it adds to the sample (artifacts). Leaving

Hi, <p>apparently, I didn't delete my test samples ... I found them. :) Here's a small table of what nominal bitrate fits to which quality at what sample rate. Quality levels inbetween -1 and 0 are possible, but I didn't test them. Nominal bitrates of those quality settings will be somewhere between those of -1 and 0 and therefore can be guessed. q/channels || -1/mono |

Hi: I have been curious as to Vorbis' performance at -q0 for some time now. When RC3 came out, I used a track I have here and encoded it at q0 at 11.025, 16, 22.05, 32 and 44.1khz, both in stereo and in mono. After having heard the great sound of -q 0 in stereo, I thought I'd see what bitrate I got with -q0 in mono. I was disturbed to discover that the resulting file was 9.5kbps higher

Which DSP are you running to feed your stream? (on winamp I am assuming) If you are using the new shoutcast 1.8.2 DSP, it has had a lot of problems with super high CPU load and memory leaks. Try Oddcast instead (unless you can run ices or darkice) using VBR Mp3 streaming. Nothing but happy times here on a win2k dual p2 333 with winamp (2.74) and Oddcast DSP Beta 25 connected to KasterBlaster

Hi! On March 17th I posted a message on this list concerning an artifact bug in beta4 that is audible in all available bitrates. It was this rumbling sound in the bass area. I made a demo clip, which still is available at http://www.stud.uni-karlsruhe.de/~us87/ogg/vorbis_bassrumble_demo.rar and that contains both the original .WAV and an .OGG @ 350kbps. This archive is 2.1 MB large. Today, I

Hi everyone, I'd like a bit of information about the stereo mode settings in psych_44.h of libvorbis. Specifically, about the adj_stereo structure: typedef struct { int pre[PACKETBLOBS]; int post[PACKETBLOBS]; float kHz[PACKETBLOBS]; float lowpasskHz[PACKETBLOBS]; } adj_stereo; What I am attempting to do is bring lossless stereo coupling down to the lower quality levels in

Uaaargh ... between now and the last mail, everything's gone kaploohey. But I doubt that it concerns icecast too much in this case - the streaming computer has a cpu load of 90-100% for no reason (it's an athlon 1ghz with only winamp and ssh and the system monitor running under win98). The playback on the streaming computer sounds good, though, but what reaches the client side is no more

Hi again, shortly after beta 4 came out i noticed that rumbling artifact oggenc puts into a certain tune of mine. Back then, it was even audible at an ABR of 350kbps. Now with RC2 that bug is completely gone at bitrates of 128kbps and higher. I can hear it again at 96kbps and it becomes more apparent with lower bitrates. At 64kbps, I assume, everybody should be able to hear it. This is not a

Not much more to say, thanks a lot to all developers for your hard work! I have no chance to reach vorbis.com (CVS works, slowly ;) ), I take that as a very good and promising sign. <p>Moritz --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this list, send a message to 'vorbis-request@xiph.org'

How long has that system been up? Back when I was using Winamp/Win98 as a stream source it would do that after a day or two. Sometimes closing & restarting Winamp would help - more often I'd need to reboot. Win2000 would probably work better - of course ices on Linux would be best :-) -bg ----- Original Message ----- From: "Moritz Grimm" <gtgbr@gmx.net> To:

*This message was transferred with a trial version of CommuniGate(tm) Pro* I use real server to broadcast live video streams from my studio ( using icecast to broadcast the audio ) to clients using real player ( of which there also is a free version of ) and I don't pay a dime. I don't know how much more free something can get. But, you sir, can believe whatever you'd like to... -----

Hi! Propably a stupid question, but where can I get those brandnew encoders from? It'd be great if someone could post those URLs to the list for people like me who don't read any forums (no time, no fun :P). Thanks in advance! Obtw, CVS would be fine, too ... but as long as the new code isn't merged to the main branch I feel pretty lost searching for it. Any help here would also be

Hey Kevin! Once you start dropping under (I think) 32kbps, the codec naturally starts losing stereo separation for the benefit of quality. If you really want perfect stereo at 16kbps CBR (this is horrifically low in my opinion) you might be better off splitting the audio and encoding each part at 8kbps CBR. Or, there may be a magic "enforce 100% stereo" one could pass? (doesn't look

Hi, I've just read this on Vorbis Xtreme site: "11. YOU SAY THAT OGG VORBIS IS PATENT-FREE, BUT I SAW A PATENT NAMED 'JOINT-STEREO' ON FRAUNHOFER'S PATENT LIST? SO OGG VORBIS ACTUALLY ISN'T PATENT-FREE SINCE IT ALSO USES JOINT-STEREO? No. You can't judge on a patent just by looking at its name - what's 'inside' is what matters. So if the name of the

Hello all, I created today a fake stereo piece of music (the left and right channels were completely equal), and encoded it with the all the modes the RC2 encoder supports, and found that: * * dual * waste * waste * * mode * joint * stereo * in * in % * * * stereo * /2 * kbits * of JS *

Hi, I've read the Vorbis stereo documentation on square polar mapping and currently reading the source code to understand it. But there are some things which I don't quite understand and hope I can get some guidance on. I understand the decoding/decoupling part as it is the same as the one described in the stereo docs: From mapping0.c: /* channel coupling */
