Digital Ear evaluation of Vorbis beta 4
For those who haven't yet seen this:
EarGuy's Digital Ear (physiological model of the ear based on work by Frank
Baumgarte) has just finished rating the sound quality of Vorbis beta 4 at
128 kbs using 30 random 10-second selections of music:

Peri-ear
Found this.

The peripheral ear model is based on the structure of
Eberhard Zwicker's "Analogmodell". That model consists
of analog electrical elements.

no ring in ear
Hello.
I have two snom200 ip phones and 1 mp108fxs (audiocodes 8 fxs) and i
dont get a ring in the caller phone when I dial from a snom200 to the
other snom200 or the mp108fxs, I made a debug with ethereal, and I can
see a "Ringing" packet being return from the called snom200 or mp108fxs
to the asterisk box, but it is not being re-transmitted to the caller
snom200.

Virgin Radio launches an Ogg stream
Apologies if this is a bit of a commercial post (I've not been lurking
long), but you might like to know that the world's most listened-to online
radio station has just launched an Ogg stream. (As of today!)

Can compressed music sound better than uncompressed?
I quote from "Principles of Digital Audio" by Ken C. Pohlmann:
"Because perceptual coders tailor the coded signal to the ear's acuity, they
similarly tailor the required response of the playback system itself. Live
music does not pass through amplifiers and loudspeakers, it goes directly to
the ear. But recorded music must pass through the playback signal chain. Much

space in column name
I read a table from Microsoft Access using RODBC. Some of the variables had
a name with a space in it.
R has no problem with it but I do.
I cannot find out how to specify the space

simple q: returning a logical vector of substring matches
I'm a relative R novice, and sometimes the simple things trip me up.
Suppose I have
a <- c("apple", "pear")
and I want a logical vector of whether each of these strings contains
"ear" (in this case, F T). What is the idiom?
Quizzically,

Illustrating kernel distribution in wheat ears
Dear all
R2.10 WinXP
I have a dataset dealing with the way different wheat cultivars build their yield.
Wheat ears are organised in spikelets where the spikelets can be numbered from the bottom, with even numbers on one side and odd on the other.
I know how many kernels there were in each spikelet after some months spent counting them...
Now I want to illustrate the differences between the

Glusterfs/CTDB/Samba file locking problem
Hi guys,
I try to set up two identical installed up to date CentOS6 machines with Glusterfs/CTDB/Samba .
I have set up Glusterfs and it works. I have set up CTDB from CentOS and it seems to work too.
Samba is AD integrated and works mainly.
The main problem is that file locking seem to not work between the machines at all. If two Win7 clients try to open an document

Phone still rings while on a call
Hi All
I have some grandstream phones registered to my asterisk and all internal, external, voicemail services etc are working very well.
I am not sure that it is a problem more so an annoyance. If someone dials my extension number or external DDI while I am already in a call rather than skipping to the next priority in the dial plan for example voicemail the line continues to ring and while in

Stange question...
Ok, guys... Please be gentle with me. I have what is going to be the
strangest question you will have ever heard, but I have no idea what to
tell this person.
I set up Asterisk 3 or 4 weeks ago, everything is running smooth. My
receptionist has told me on two different occasions that she tried to
transfer a call by pressing "#", and she heard a buzz noise in the phone

OH323 doesnt hear ringing
I have Asterisk running with a combination of SIP and H323 clients. I am using the OH323 module instead of the H323 one.
When the SIP clients ring each other, they can hear a ringing noise in the ear peice to let them know that the other parties phone is ringing. However, when the H323 client rings a SIP client, there is no ringing sound at all, although as soon as the called party picks up the

Why echo occurs
Hi all,
Can someone give me a simple rational explanation why a $5 analog
handset gives me no echo whatsoever on an analog PSTN line, but
PSTN-VoIP devices such as the TDM400 and Sipuras do and thus require
software-based echo cancellation. Surely a $5 analog handset does not
have an "echo canceller".
The echo I mean is when I hear myself while talking to another party.

FLAC: headphones
hi flac list!
I'm not sure if this question can be asked here, but here you go (it's a
question for audiophiles only):
I encode CDDA tracks to FLAC and play them on my Pocket PC (PDA). I'm
looking for a high quality headphone to connect to my Pocket PC, but it must
be an in-ear one but not like these:

Headsets for Cisco 7940/7960
What headsets have people found work well with the Cisco 7940 and 7960
phones? To date, I have tried a couple of the headsets within the
Plantronics H series (H41-N), and noticed that the volume of my speaking
is lower over the headset than on the regular handset. I am currently
looking for headsets that are known to work well. I do know that Cisco
lists the H-91 and H-101 as certified to
