lowpass option (Was: RE: channel coupling in rc2)
I would very much like a lowpass option because for FM radio broadcasting I
don't want to encode frequencies above 15khz. I'm waiting for this option
before switching to ogg from mp3(lame).

channel coupling in rc2
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?
Thanks for your patience,

5.1 surround channel coupling
>Yesterday I have finished writing the ambisonic pan filter for oggenc.
May I ask what this "pan filter" is?
I made some tentative suggestions for coupling Ambisonic B-format in a post
"Vorbis Ambisonic coupling" on 4feb07
I gather from the last monthly meeting, that some of you, including Monty, had problems with the phase behaviour of B-format.

Channel coupling in Vorbis
I saw from the interview on Slashdot that there is no support for channel
coupling in Vorbis. I would like to help work on that. Has anything been started
about that? I don't know yet whether if could work "in real life", but I have
started to work on a way to do adaptative coupling between two channels (by
finding the best transformation to predict one channel from the other).

5.1 surround channel coupling
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?

Peeling vs Coupling
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 rate,
channel coupling type

Channel Coupling and Quality (-q 5 vs -q 4.99)
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

Square Polar Stereo Coupling
Hello,
I've read http://xiph.org/ogg/vorbis/doc/stereo.html and the Vorbis specs,
but I haven't got a clear concept of how does the Square Polar Mapping
works. I mean, in the "Ogg Vorbbis stereo-specific channel coupling
discussion" document, it's described how the decoupling process works for
Square Polar Mapping (and it is fairly clear explained), but it does not

Contos3->5 upgrade, smbmount is gone?
I solemnly puke upon people who break things and call it progress. Get

I upgraded Centos3.8 to Centos5.4; smbmount is gone. Mounting a WinXP
share requires a new instantiation of the old command

Encoding with Channel-Coupling
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

Sorting messages by date
I've recovered a load of messages from a different mail server without it's

display in Outlook Express (yes, you may puke at this), all as today's date.
However when I read them in Pine, the date of each message is displayed
correctly, but they're in no particular order whatsoever.

Not accepting nil values in fields when CREATING a record
Hello,
I have a question for you.
In my application, I want to make sure that the database doesn''t have
any NULLs in fields.
I can''t use validates_presence_of, because it will puke if there''s an
empty string ("")
So... is there an EASY way to check if a list of fields is null?
Right now, I''m doing:

Measuring the change in coupling of time series through time.
I am trying to work out what analysis to perform on two coupled
time-series. I want to ask how the coupling (i.e. lag or correlation)
changes over time.
The time series are of 4 replicate pred-prey time series where the
series appear more tightly coupled at peaks but drift apart during the
decline and trough phases of the cycles.
The time series are short (70-80 weeks/points replicated 4

Recommend a pdf reader?
Hello!!!
evince is a really good ubuntu pdf reader, but for some tasks I would like to use mouse button 1 for panning, because I use a netbook touchpad. Currently panning is only available using mouse button 3, which I would need to use a separate mouse for.

Channel coupling
Unfortunately nobody has answered to my question about the channel mapping.
:-(
Are there any new ideas how save the channel mapping in multichannel vorbis
streams?
In addition it might be interessting thinking about using channel coupling
for storing the same content in different langauges (because many things
like background music are supposed to be the same). But there would be the

Resample and Relay Using Icecast2
Hi Robert,
Icecast itself doesn't do any resampling of audio streams it receives.
One would likely craft a solution that listens to the original stream
and re-encodes on the fly, providing those alternate bitrate streams
back to Icecast. I've heard people doing this with liquidsoap and other
source clients, and a bit of server-side magic.
Some quick Googling provided me with this link
