MusicOnHold Loudness/Distortion
For whatever reason, the music on hold is extremely distorted and
loud. It didn't used to be this way and I haven't changed anything,
yet it persists. This is on all the channels we use (SIP, IAX2, Zap,
ALSA). Can anyone help with this, or has anyone seen this? The mp3s
play fine on any computer and haven't changed since they did work.
Those wishing to hear for themselves, feel

Chopping off the wideband?
If I encode something in ultra-wideband, can I decode it in wideband by
chopping off bytes in every frame?

MOH distorted voice in Native and MP3 format
Hello,
I have been facing an issue that voice is getting distorted sometimes in MOH
(MusicOnHold) application.
I have checked and confirmed that lame is properly installed, even tried
native formats (ulaw, alaw, gsm), but the randomly seen distortion in MOH
can't be eliminated.
I came to know about requirement of timing device for MOH and MeetMe and a

X11 device distortion (PR#10666)
Full_Name: Thomas Zumbrunn
Version: 2.6.1
OS: GNU/Linux (openSuse 10.3 2.6.22.13-0.3-default)
Submission from: (NULL) (131.152.125.199)
With my particular X11 settings, the width to height ratio of the x11 device is
distorted, with the width being half that of the height. This results in wrongly
proportioned plots, wrongly positioned text etc.
Other devices are not affected.

Help with IAX , voice Distortion or Breakage.
Hello all,
We have the following problem:
When calling via iax, the sound is off after a while - most often after
about 5 minutes (sometimes later or earlier) - at one end or at both
ends. While the channel is up, and packages are still being transmitted,
you just can't hear anything. Sometimes you can hear something just a
little, but with the voice greatly distorted, sounding like a

Further bug discovered with the Directshow decoder
Hi good people,
Just to inform:
I finally fed FFMpeg2Theora with a .VOB input, and the .OGV output produced played back beautifully in VLC, both audio and video. However, the same output .OGV file gave clicks and pops in the audio when fed through Directshow programs. I played it through Windows Mediaplayer as well as through Winamp, with the same crackles in the audio, and this leads me to

Music On Hold distorted
I have searching the forums here on how to get Music On Hold working
and I have been able to get * to accept a command for MusicOnHold
and for Meetme after loading the ztdummy module. I used the default
config for /etc/zaptel.conf since I saw no guidance on this. My problem
now is that when I activate MusicOnHold, the sample music file sounds
very slow and distorted. My best guess is that it is

Distorted VM with iax2 with ilbc and jitterbuffer - bug?
Two asterisk boxes 150 miles apart, both cvs-head as of this morning
(and since Sept 27th), connected via iax2 with low-utilized ds3 internet,
C7960 calls exten on remote system (also C7960), and call goes to VM.
No other calls in either system (eg, no load).
Both boxes have iax config'ed as:
trunk=yes
allow=ilbc
jitterbuffer=yes
Recorded VM messages are very distorted.

oggenc adds severe distortion
Hi all,
I routinesly rips my CDs to WAV and then convert to ogg vorbis format
for use in my car and portable player. I don't usually notice anything
amiss, but on the last track of Mike Oldfield's "Music of the Spheres"
album ("Musica Universalis", at the very end crescendo), the converted
.ogg file exhibits terrible distortion (sounds like digital clipping).

Chopping a two column data frame by rows into a three dimensional array.
If I have a two column data frame like:
> dat <- cbind("x"=c(1:100),"y"=c(100:1))
How can I create an array that splits every ten rows of that data frame
into a third dimension of an array so that:
> newarray[,,1]
,,1
x y
1 100
2 99
3 98
... ...
10 91
,,2
x y
11 90
12 89

RFD: With echo and other distortion, can ulaw/alaw line quality ever be good enough for faxing?
Folks,
I've been following recent discussions regarding echo and echo training with
much interest, since it's a problem we've never been able to eliminate here.
We're facing two challenges presently, and they may be related (or not):
a) Cisco 7960s in the office here echo back to our staff, but the customer
hears decent sound.
b) We've yet to be able to pass faxes through

Digital Line Distortion
Firstly, the problem...
Ever since I installed and setup asterisk, I have had various problems,
initially it was echo caused by the ISDN (isdn4linux) card I was using.
So, I upgraded to the X101P from digium. I still had echo, so I figured
it was also caused by the ATA186 (cisco) I was using. So, I upgraded
again to the TDM40B quad FXS card. This solved pretty much all my
problems, except

Distorted audio over Eicon Diva Server BRI
We are experiencing slightly distorted audio with playing of recordings on
our Asterisk server when the call comes in over our Eicon Diva Server BRI
card. An example is an incoming call to IVR and playing some of the standard
Asterisk voice prompts. Note that there is no audio problem with internal
access to the same recording. Neither is there a problem with calls not
involving the playing of

Should Speex VBR Introduce Distortion?
Hi All,
I've run into a small hiccup in encoding my audios with Speex. When I
encode audience laughter and applause with 'speexenc' (version 1.0.1),
the result is quite acceptable... until I enable VBR. Then it distorts
horribly.
My understanding of VBR is that it frees the encoder to vary the number
of bits emitted to better maintain the quality requested, and so I would
have

iax connection and 1 way distortion
I'm new to * and I have my * box connected to another * box located at my
ISP via iax2. Using ilbc everyting works fine but with any other codec I've
tried (gsm, ulaw, alaw) there is severe distortion on the sound going out of
my box as well as a second or two of delay. The incoming sound quality is
fine. This happens even if the outgoing sound is coming from the voice mail

IAX voice distortion with full upload channel / SIP ok
Hi,
this is the scenario:
One * is placed in a central location with more than enough up/down
bandwidth. One * is placed behind a DSL 3000/384. Both * are linked via
IAX trunking. Everything is fine until the upload channel of the remote
site is filled with a download, then heavy voice distortion starts. Well
of course this is expected. So I fooled around with HFSC QoS scheduling

Standard Sound Files Distortion
I've been noticing lately what seems to be some distortian in the standard asterisk sound files, used for voicemail. These files are stored on the local Asterisk system. When Asterisk plays them, I can hear some cracles and pops. I'd never noticed these until recently.
I did a little test.
This sounds fine...
