Large codebook?
Hello.
Earlier I asked if it would be possible to use one common large
codebook for all audiofiles. Can you estimate how the following
system would work?
1. The audio would be divided to 16 samples blocks.
2. For each block, the first sample would be stored without any encoding.
3. Linear interpolations between the stored samples are computed.
4. The residues (length of 16 samples) between the

One codebook for all audiofiles?
[ I'm not in the list because I didn't find a digested version; please
move the lists to sourceforge.net, and we would have the digested version.
I read the replies from the archive. ]
Hello.
Would it be possible to allow Vorbis use the same codebook for multiple
files? I could keep a 650 MB codebook on CD-R and use that for all my
audiofiles. If that is possible, how much the

repeating rows or columns within a matrix
Hello
Spse I have a matrix, say
1 2 3
4 5 6
7 8 9
and I would like to expand it by repeating rows within the matrix, to
get, if the repeating factor is 2, say:
123

(or columnwise as well) . There must be a smart way of doing that?

Index matrix to pick elements from 3-dimensional matrix
Hi all
Suppose I have a dim=c(2,2,3) matrix A, say:
A[,,1]=
a b
c d
A[,,2]=
e f
g h
A[,,3]=
i j
k l
Suppose that I want to create a 2x2 matrix X, which picks elements from
the above-mentioned submatrices according to an index matrix J referring
to the "depth" dimension:
J=
1 3
2 3
In other words, I want X to be
X=
a j
g l
since the matrix J says that the (1,1)-element should be

Lossless compression
I was just somewhat curious as to what lossless compression is used... is
it just huffman?

Monty on holiday
Hi folks,
My wife and I are taking a long weekend to celibrate our anniversary. I won't
be around again until Wednesday to answer email or do anything else on Vorbis.
Yeah, I know, I usually answer my email once a month anyway (so likely no one
would notice me being gone), but just so folks know if anything really juicy
comes up :-)
I'll be merging my latest branch with mainline

Frequent RRL false negatives when using multiple server processes on Linux
Hi,
Please advise how to use Response Rate Limiting on a server which has
multiple NSD server processes (nsd.conf server section has server-count
> 1).
We have a problem with NSD v3.2.16 repeatedly unblocking and blocking
again a single source which is flooding positive queries at a ~steady
700 qps rate. rrl-ratelimit setting is the default 200 qps. The
unblock-block happens multiple times

samba 4 domain join to win 2008r2 level DC w/ a schema with exchange 2010 extensions: replication after the join is broken
I tried to join a samba4 to a win2008r2 level domain (OS level 2012) running exchange 2010.
The join succeeds but the later replication is broken due to schema differences.
In order to to find the cause, I started a test setup with:
* a win2008r2 DC w/ minimal AD
* upgraded the schema and the OS to 2012 (function level is still 2008r2)
* and added a exchange server to the domain.
And that is

Rcmd install problem: "cannot open the connection" and "No such file or directory"
Dear all,
On Windows XP with R 2.8.0, I get the error message below when I try install a package from the command line.
(Installing as a local zip-file from the menu in the GUI works fine.) Could anybody point me towards the source (and solution) to the problem?

Adpcm, 6KHz codec
Is there a way to play adpcm, 6KHz in asterisk? If yes, where can we get
this codec?
Thank you.

ADPCM 4-bit, 6 kHz
I found some posts regarding this issue dating of September 2003, but no
real answer.
The ADPCM format supported by Asterisk (the .vox files) is 4-bit, 8 kHz. I
need 4-bit, 6 kHz, which is also a widespread Dialogic format, to help
migration.
Is there an existing format/codec for this? If not, can I make myself a
shared object in /usr/lib/asterisk/modules? Is this easy??? :-(
Thanks,

ADPCM support with RECORD FILE
I want to record audio in ADPCM format. According to the "show codecs"
output of Asterisk, it looks like it supports adpcm. But I do not know what
to tell the "RECORD FILE" directive in my AGI script.
The RECORD FILE command usually has this form:
RECORD FILE <filename> <format> <timeout> [BEEP]
It records fine in WAV or GSM if I enter "wav" or

IAXy and ADPCM codec problem
Hi everyone,
I'm using the IAXy boxes and i'm having some trouble when I use it with
the ADPCM codec.
When I use the ADPCM codec only one person (out of the two of the
conversation) is able to hear the other, but when I switch to ULAW codec
everybody can hear the other.
The ULAW codec is too heavy for my bandwidth (64Kbits/s) and its sounds
choppy, the ADPCM codec sounds good but only

ADPCM - vs - G.726
I have been looking at the medium-rate codecs in Asterisk - ADPCM and
G.726. Both of these are adaptive PCM codecs - the G.726 one is a little
more expensive in processing power, however both are 32k bit-rate.
I am experiencing problems using G.726 where the audio level is high. It
produces loud clicks as if clipping. For quiet audio however, it seems
fine.
ADPCM (Digilogic VOX?) seems to be

ADPCM codec and IAXy device
Hi All;
I need to buy one IAXy device, but I discovered that
it supports only g711 and ADPCM codec, so I was wonder
that it does not support g729 or GSM?!
Anyway, what is that ADPCM and how much it consumes
bandwitdh? Also, asterisk support such codec? What its
name in the configuration?
Any advise?
