Increasing the speed of speex playback
You're asking the wrong question. The question is not "why does it
would bad with Speex?", but "why does it sound good with LPC10 and
MELP?". And the answer is that both are vocoders. Try dropping
frames/subframes with anything else (Vorbis, MP3, G.729, u-law, ...)
and it'll sound terrible as well. The only reason it sounds good with
vocoders is because the

Increasing the speed of speex playback
Hi. I'm Bill Cox, and I volunteer a bit for the Vinux project, which
is Linux for people with vision impairments. Most blind users use a
closed-source speech synthesis tool called voxin, as it's very easy to
understand at high speed. I would like to make TTS synthesizers based
on large recorded vocabularies of actual speech, but to make it useful
for the blind, I need to be able to

Increasing the speed of speex playback
Here's one clue about whatever is causing the low quality speech.
Speech sounds terrible at 1.01X faster, and it sounds excellent at
normal speed (1.0X). So, the main problem is something that breaks
with any change in frame size in the decoder. Any idea what that
might be?
Thanks,
Bill

sshd refusing connections problem
We have been having a problem with sshd on our shell server.
This has been happening since March 4, 2003 or before IIRC. Initially I
thought the next OS upgrade, to 4.8 would fix this. I am accustomed to
haveing little things go away in a month or two.
I think we jumped to 4.7-STABLE on Feb 28, 2003. Some exploit fix

Increasing the speed of speex playback
Hi, Steve. I tried your the time_scale_tests program, and it works
well! Especially for low speed changes, it's the best I've heard so
far.
For high speed increases, there is what sounds like static added to
the sound output. I've attached two sound samples of high speed
speech, which is a 4X speed up of a popular TTS voice in the blind
community (voxin/Eloquence). I've sped

Bug#298291: logcheck-database: Printer out-of-paper reported
Package: logcheck-database
Version: 1.2.34
Severity: minor
I have parallel port attached printer and kernel reports whenever
printer is out of paper:

However, this is not a situation that should be reported by default
(IMHO) by logcheck sending report email. Thus I propose adding

Calling C implementations of rnorm and friends
Well,
For this particular use case why not just transform the parameters at the R
level and then call the existing function? Is there not a closed form

Multi-Channel/Stream support?
Hi all,
I'd like to know how well Speex handles multiple input streams. More
specifically, if i have 4 streams that are playing at "the same time", how
well does the CODEC handle switching from one stream to the next to process
the audio.
The reason i ask is this....My project up until now uses the MELP CODEC
which didn't specifically have the ability to handle multiple

Increasing the speed of speex playback
Hi, Jean-Marc, and thanks for the quick reply. Let me just say I'm a
huge fan of speex, and the work you've done. I actually barely
understand what I'm reading so far in the source code and
documentation, just enough to understand just how cool the algorithms
are.
LPC10 and MELP allow me to speed up speech with a simple hack on the
decoder frame size. Playing fewer samples per

is it possible to bring speed below 1000 bit/s
Hi folks,
I am totally new to audio streaming codecs, and just looking around. Trying to
figure out what else I can put on top of my very long list of projects.
So a few days ago I figured out that fldigi a digimode application for Amateur
Radio supports a dual 1000 Baud PSK mode. I thought "that's fast" and started
looking around which sort of Data I could put into that.

Bug#306388: add ignore line for udhcpd
Package: logcheck-database

Hi,
the following two lines should be added either to ignore.d.server/dhcp or
ignore.d.server/udhcp to ignore messages from udhcpd (other lines may be
necessary)

Bug#295560: logcheck: Please include filename when reporting "invalid regular expression"
Package: logcheck

I have a couple of home-made logcheck ignore files, and happened to

Issues/thoughts re CentOS-4
This is a list of issues for discussion for CentOS-4. Most of it is
based on my experience from building/maintaining CentOS-2 and observing
CentOS-3. I have not seen the CentOS-4 beta yet so I don't know if any
of this is already done. If these have been discussed on IRC then
perhaps someone could produce a shot summary of the outcomes....?

Increasing the speed of speex playback
I was able to easily hack in an option to play back at different
speeds. For example, using "speexdec --speed 2.0 file.enc file.wav"
plays back encoded file.enc at 2X speed. What I did was divide
st->frameSize and st->subFrameSize by the speedup, and added a
SPEEX_SET_SPEED decoder control for the nb_celp decoder. This
produced speech that was 2X faster than the original.

Increasing the speed of speex playback
Hi Bill,
Any attempt to alter speed by simple insert or dropping produces poor
results. Even if you can get it to sound smooth, the resulting pitch
shift is horrible. You really need to use a transform that alters speed
smoothly, while maintaining the original pitch of the voice. If you look
in my spandsp library you will find a module which does exactly this,
using an algorithm called

Consistency regarding compiled Cortado 0.6.0 sourceand the official binary
It should probably not be necessary in my case to compile a custom version of the Cortado applet-the official binary works fine, and may be advantageous over a locally-compiled version (regarding compatibility with 1.1-era JVMs), as was mentioned in a previous message. My interest was to include the corresponding source code when distributing the official binary (i.e. as would be required for

Accessing ISDN with avm bluetooth hardware

This is my first message to this list, so I hope I am not breaking any rule with my post.
My question is the following: can I establish a voice connection over an ISDN interface by using a
bluetooth dongle to connect to the ISDN access point?
Here follow the details:
