Suitability of speex for use with noisy, non-voice source material?
Question from new subscriber -
I'm working on a project to connect to remotely connect to a short-wave receiver via a dial-up PPP/IP circuit. Turns out the dial-up circuit is only stable (useful) to 14.4 kbps (faster modem training produces so many link errors that the net circuit quality is unusable - one end is in a remote, rural location), so looking for codec that can fit within this

Low-bitrate audio encode/stream application
Hello Thomas,
You are correct - the application is basically for secure remote access to
ham CW (morse code) station. I believe the solution will be based on low bit
rate MP3 streaming for receiver side (MP3 allows use with existing CODEC in
client side, which could include Win CE or Linux palmtop type form factor,
and the audio source would just be "voice grade" material on a mono,

lowpass recommendations?
A while ago someone asked about a low-pass filter for oggenc and was told to get AFsp and filter outside of Oggenc.
Well, I got it, and am totally lost (It's way more complicated than SOX) so now can anyone briefly describe what type of filter I should set up (FIR, IIR, all-pole), why one is better than the other, and if you have filter coefficient files lying around (lowpass, 19 or 20 kHz

No Voice - only "noisy audio"
Hi Folks,
I'm trying to use my mobile as a trunk via bluetooth - calls done in a
softphone go thru GSM network and calls destinated to my mobile are answered
at the softphone.
I have asterisk configured to do so but I'm facing an issue - Audio is
audible but it?s not intelligible. I feel like the audio is breaking.
Below is the asterisk log. I also get lots of ?hci_scodata_packet: hci0

Write pure sine to *.ogg directly?
Hello,
I am author of a Morse code training software written
in Perl at http://starling.ws/morse
Currently I output to *.wav and, if on Unix, convert to
*.ogg. And that's okay for a trainer.
But I have desire to upgrade the project to a real-time
communication tool...or at least a Morse code audio
mail routine. And I should like to avoid *.wav.
I'd like some means of writing a pure

Thousands Separator
I am a new R user, and am struggling with how to add a comma to the
tick mark labels in a bwplot or a boxplot.
I think the default values of the labels are fine, I just want them
to appear with commas.
If I use the function boxplot, I can then use
axis(2,labels=format(axTicks(2),big.mark=","))
but that just overlays them on the existing labels which I don't know

CBC radio's science show archives Ogg
Earlier today while listening to CBC radio's national science show
"Quirks and Quarks", I was pleasantly surprised to hear that their audio
archives are now offered in Ogg, in addition to mp3 and real. This is
the first CBC show that I am aware of that offers their archives in
formats other than the usual real/wma/qt.
For those who don't know, CBC is Canada's only

Alsa pulseaudio & procmail
Hi,
I'm using a program called morse to generate morse code signals when mail
is received. This is done by calling this program depending on de subject
or from of the incoming mail.
THis worked fine on CentOS 6 but since I'm using CentOS 7 it does nt work
anymore.
In my procmail logging I get:

noisy quantisation
The following creates a point process version of a sinewave (maybe
there's a better way):
p<-amp*cos(2*pi*freq*(1:n)/n ) + 0.5
as.numeric(runif(1:n)<p)
I get something like this:
1 o oo oo o o ooooo o
0 ooo o o o o o ooo ooo
In case it's not obvious, this is a noisy version of
1 ooooooo ooooooo
0 ooooooo

Best way to select good points in a noisy signal ?
Hello,
When I plot y=f(x) from the file xy.txt (
http://www.nabble.com/file/p18773387/xy.txt xy.txt ), I can clearly see a
trend.
Is there a function or a package able to take the median value of y for an
interval of x (x +/- a defined value) to plot nice graph (at least a better
one) ?
Thanks in advance,
Have a nice week-end,
Ptit Bleu.

smoothing noisy data with a twist
Hi,
I have a set of observations (x,y), derived from a previous estimation.
For each observation I also have an estimated variance s(y) derived from
the first stage.
The problem is that I need to smooth the data (x,y) while taking into
account the fact that the y's have been estimated at a previous stage
and thus already come with a variance. So, if I smooth the data I
somehow need to

Noisy/Clicky hangup
When I call in from an outside POTS line to a Zap channel, and the call
ends, it seems like the hangups are very "sloppy." I see Asterisk give
the hangup command, but on my phone there's lots of clicks and the line
acts like it's staying open for several seconds, then I hear a phone
ringing sound followed by "If you'd like to make a call, please hang up

Snom200 -> C7960 noisy?
When a Snom 200 (v2.1l) calls a C7960 (v4.4), both using g711u as default,
the conversation is extremely noisy from the Snom to the Cisco, but clear
in the reverse direction. Using a sniffer, I see packets from the Snom to
the Cisco of 87 bytes and Cisco to Snom of 214 bytes. Asterisk is CVS from
Saturday.
The communications between the two was working fine on Saturday, however

problem of "when memory become 50% or more then sound become noisy?"
Dear all,
Currently I am using asterisk 1.4.23.1. . Over the period of 1 week,
the memory in use starts off at 50% and
continues to climb until it hits 99%. When memory usage ratio become
50% or more, the quality of calls become
extremely noisy. The call quality goes back to being perfect once I
reboot the machine,
but I was to try and avoid having to reboot the machine every week.

[Bug 124979] pam_succeed_if.so generates noisy secure syslog msgs (fwd)
For those of you using Dovecot on Fedora, the noisy syslog is fixed:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=124979
I'd suggest getting the pam SRPM from Rawhide (Fedora development tree) and
rebuilding, to minimize dependency issues.
(I haven't tried this yet. I'm just forwarding the bug-closing report.)

Noisy sound quality with Blackfin in WB-mode
Hi Bernhard,
Can you confirm I'm understanding everything correctly? You encode with
the same encoder and then decode with either A) blackfin assembly and
fixed-point or B) fixed-point only on Blackfin. Then A) sounds bad and
B) sounds good. If you do the same in narrowband, it sounds OK. Is that
correct? If that's the case, it's *probably* some kind of bug and/or
invalid assumption
