Hi, I'm planning to re-encode all my MP3s with Ogg Vorbis but I wanted to wait until 1.0 was released because of channel-coupling. I read that would increase quality about 40% at the same bitrate and I didn't want to encode my files wasting all that bitrate ... Now, since 1.0rc1 is released I am wondering if I am actually able to use channel-coupling right now. I installed all the newest libraries and the latest version...

This question has probably been asked a zillion times, but I'm either too dumb or too lazy to sift through the archives, so I'll ask it here again: Which of the bitrates in RC2 utilize channel coupling and which don't? And when can we expect to choose for ourselves whether we want to use channel coupling at any particular bitrate?

Hello, With some trepidation I've come to inquire about platform requirements for * after having spent a couple of hours searching and browsing the archives and skimming the Handbook (very nice). I've found recommendations for 800-1000 Mhz and 128-256 MB RAM machines. My curiosity is not about what machine I need to start using * to support live comm ops. Rather, I want to know if a

After reading the documentation on the different types of channel coupling I began to wonder what effects this might have on bit peeling. Say for instance an audio file is encoded at a rather high bit rate with channel coupling type "X". Later on the same file is streamed, and is peeled down to a much lower bit rate in the process. However at this lower bit rat...

Hey everyone, I've added Ogg Opus support to my Adobe Premiere plug-in here: http://github.com/fnordware/AdobeOgg Now I'll add Opus support to me WebM plug-in too. I've got this Opus stuff mostly figured out, but I have a few questions. Here's one: What do the numbers in mapping mean? I see that opus.h refers to the Vorbis channel mapping order, so does mapping in Opus take

I saw an article this morning about the RH developer toolset. basically it includes a couple of packages like PHP python mysql (etc) that are later packages than that included in the released version like a 6.4 for example. So instead of php 5.3 with patches it would be php 5.4 and so on. That is great for a couple packages - but what about more up to date libraries like glib. 6.4 is way behind

Try this: make encoder invert polarity of right (or left) channel on input and listen to output files (at about 128 kbps). I know that I am being nasty, but some software uses this kind of trick to produce 'surround'-like effects; this stuff causes channel coupling to puke (works fine with RC2 when channel coupling is disabled, tried with my Winamp output plugin which has an option to do that; also works fine with LAME @128kbps and Vorbis beta4/RC1). Idea: auto-disable channel coupling when it doesn't gain anything. -Peter --- >8 ---- List archives:...

Dear All: I studied the stereo couple documents and now confused, I wonder why it can be done like that, and what is the principle behind that. I think i am confused perhaps because i have no background knowledge, can you help me out? Also, when doing the T/F transform,we used MDCT, so it means no imaginary part. And i am much puzzled about the angle in the stereo couple,what does it mean?

...gets the right channel of the first coupled stream, and so on. So we can see in your example that the encoder coupled front left/right and rear left/right into pairs, and kept front centre and LFE as descrete mono. https://tools.ietf.org/html/draft-ietf-codec-oggopus has more detail about how the coupling works. Hope that helps, -r

It obviously would be nice to have such a mode available, for e.g. DVD audio compression. Apparently, the list doesn''t tell me too much about it. My questions are: 1. What is the current status of the 5.1 channel coupling in Vorbis? 2. If I''ll be interested in participation in its development, what is the recommended reading? -------------- next part -------------- An HTML attachment was scrubbed...

Hi all, I've searched everywhere to try to find out how to do this and have had no luck. I am trying to construct identifiers for couples in a dataset. Essentially, I want to identify couples using more than one column as identifiers. Take for instance: obs unit home z sex age 1 015029 18 1 1 053 2 015029 18 1 2 049 3 015029 01 1 1 038 4 015029 01 1

Hi, Yes I'll do that. The situation has changed a lot since then and lld got support for other architectures, in particular aarch64. But if I remember correctly, there was a discussion whether we should bring this ABI oddness to the ABI standard body (if exists) or not. I wonder if there was some progress on that.

Hi, all, I''m a newbie on dtrace and the problem I am having is: For processes which have been running for more than a couple of hours, dtrace doesn''t seem to be able to trace(I waited for at least one hour and didn''t see anything happening). However, it works every time for a relatively new process. Any insight or help will be appreciated. This is my machine:

Hello all, I'm using the directshow filters by Tobias. Yes I know they are not supported here :) The vorbis encoder (I really mean encoder, not decoder) by tobias works good in 2 channels mode, but with 6 channels it exchanges the order of channels while encoding. The front center goes to the front right, and the like. I have reported the problem, but Tobias gives no signs of life. I want to

With reference to the previous query, I think, i miscalculated the offset, just recalculating. 1. without instruction combining coupling member variable, is at:   %struct._FRAME_DATA* %2, i32 0, i32 5   where "%2" is defined as:   %arrayidx3 = getelementptr inbounds i16* %Data, i32 1024, !dbg !446   %2 = bitcast i16* %arrayidx3 to %struct._FRAME_DATA*, !dbg !446 i.e. at 5 offset in FRAME_DATA i.e. the 6th element, i.e. co...

...'s specific volume at each depth (pressure). The volume vp (p to indicate pressure) depends on s,t, and p, and h is essentially a sum over the volume at each p. When the individual models are computed, coefficients should be chosen so that this is satisfied. How to do this in R? Without the coupling the least-squares formulation would seek coefficients a_p and b_p to minimize: sum_p(sum_p((s_id,p - a_p t_id,p + b_k)^2)). Minimization at each p is independent. With coupling, there would be an additional term: sum_id((sum_p(vp)-h_id)^2) where vp is a function of a_p t_id,p + b_k and of t_...

I'm not sure if I am wording this correctly, but I'll try. I have a Cisco 2621 w/ a couple FXO and FXS ports. I have a couple cheap analog phones plugged into the FXS ports. I am able to get * to ring those phones when a call comes in, but I cannot get the phones to dial out. I guess it's all syntax that I'm doing wrong. Does someone have a couple small snip-its to accomplish

Thought I'd throw another log on to the quality debate to liven things up a bit. Does anyone have any evidence anecdotal or otherwise on the difference between -q 5 and -q 4.99? Now, I know that the difference between them is ONLY that a lossy channel coupling is used at 4.99 and that lossless channel coupling is used at 5. So my question is: How good is the channel coupling in 4.99? Can you tell the difference? We all know that JS in mp3 sucked royally, but can anyone give testimony on the quality of channel coupling in Ogg Vorbis? Is the difference...
