Free g.729.1 implementation
1st. - I'm from Poland, we don't have (yet, and hopefully forever) software
patents.
Is there any free g.729.1 implementation for asterisk? I want to use it for my
private use (dialing into inet->PSTN gateway), and I don't want (now) to buy
codec, as I don't know if I will be using this service in future (now I just
want to test it). Any solutions? Maybe even

Polycom wideband codecs?
Doing a little research before Friday's Voip Users Conference call with
Dan Behringer.
Are any of the newer Polycom wideband codecs implemented in v1.6?
Specifically, G.722.1 or G.722.2?
Thanks,
Michael Graves

Are the Siren7 and Siren14 the G.722 HD voice codecs?
Hi Everyone,
1- Are the Siren7 and Siren14 the G.722 HD voice codecs?
2- Are these codecs only for Polycom units or are they universal across all
other SIP phones that advertise the HD voice codec like Aastra?
3- What is the main difference between the two and is it advisable to run
these over the INTERnet (not INTRAnet)?
Thanks

Asterisk G722
Hello,
I have some problems to use G722, when my client sent an invite request
to asterisk using G722/16000 codec
asterisk respond with G722/8000 codec.
I dont know exactly if Asterisk supports G722/16000 codec??
If yes how can I activate It??
Thanks.

Speex 1.1.2 - Try it on ARM
Hi,
I just released unstable version 1.1.2 that contains more fixed-point
work. Though it's still not 100% complete, enough have been done to make
it run in real-time on ARM. In order to do that, compile with
--enable-fixed-point --enable-arm-asm. All narrowband modes work in
real-time with complexity 1 (some work with higher complexity) and some
wideband modes also work (up to ~20 kbps) at

added background noise problem?
Using narrow, wideband, and ultra-wideband encoding on a short 16khz wav
gave .spx's of 3,789 ... 2,935 ... and 1,875 bytes. Even after reading the
manual, smaller files for the higher frequency encoding seems
counter-intuitive.
My mp3 at 32 kbps on the original 22khz wav is 3,866 with a quality
comparable to speex wideband on the converted 16khz wav, so speex is a 24%
improvement in size.

Asterisk 1.8.32.3 : no video (h.264)

I am not able to make a call with video support. I do not know what I am
missing to make this video call.
Codec h264 should be supported.

Digium transcoding card
Hi,
Given that the Digium transcoding card has no external connections
(AFAIK), it strikes me that it would suit a mini-PCI slot very well.
Does such a beast exist, or is it likely to? Am I correct in assuming
that this is a Digium-only product, and there is no OEM equivalent
"generic" board out there that I could be investigating? It would be
such a shame to waste a PCI slot that

AEC troubleshooting
First of all, thank you for your input Tim. That is very helpful.
I would love to hear from other people with experience of AEC and Speex.
I guess I have to split my question into to parts now.
1.
Is it a fact that using the windows multimedia API (wave audio) for audio
capture and playback makes it impossible to do echo cancellation with Speex
AEC or other EC method due to inprecise timing?

Compare to Skype
One of my user is praising Skype!!!
I cannot figure out anymore what I can improve!
This users sip show peers is jumping from 65 msec to 1800 all the time.
Of course his voice quality is like a morse code with dashes or dots of
connection time.
The next minute he calls me via Skype and it works fine !!!! What
indicates that there is no fault on his Internet connection!!!

Higher Bandwidth at lower quality settings
Hi,
I was wondering if anyone has experimented with Speex's wideband (16kHz)
mode at lower quality settings. In particular I have been using quality 3,
and with wideband input files the resultant frequency spectrum is limited to
about an upper end around 3.5kHz (almost telephony quality bandwidth). Has
anyone tried increasing the spectral bandwidth at the expense of lowering

Recommended GUI for Speex
Hi all,
I have recently added Speex support to my app (http://sbooth.org/Max/) and
am in the process of creating a GUI for the user to control the codec
parameters. I am new to Speex and as such I am not really sure which
parameters are more important than others, and deserve prominent
placement, etc. Is there a recommended GUI for people to follow or use as
an example?

Sampling Rate
Kirk,
Speex was designed for 8kHz, 16kHz, and 32kHz sample rates. If you
don't use one of these sample rates, you'll be messing up important
assumptions deep within the codec. Why these sample rates? It's
telecommunications tradition, rather than PC audio tradition.
If you want an efficient and high quality format for voice chat, try
16kHz with VBR quality 6. You should see

Speex test cases?
I'm trying to get speex to encode a bit faster, mainly by rewriting a few
functions in SSE and translating the GCC __asm__ to VC __asm.
There's 2 functions I'm targeting, first is vq_nbest which consumes 40% of
the time at high complexity and split_cb_search_shape_sign. Which consumes
just over 30%. I've split out two functions from:

mingw (native gcc for win32) doesn't officially support using gcc 4.0
and 4.1 yet (apparantly there have been some issues), so there are no
binary packages. But if you think it helps, I can compile gcc 4.1 and
give it a shot.

Better audio in than just 8k
Hi all,
If I use a SIP softphone and set to gsm codec clearly I get a 8K sample...
if I change that to something like opus I get a much better sounding
input...
How do I get a "better" than 8K sampled input ?
I "desire" to have that input be from a pipe. I have cd quality audio in
this pipe - I would like to get that audio into asterisk to then send out
to endpoints. How do I

Speex hardware requirements?
Compared to todays PDAs the GameBoy Advance (GBA) is low spec. it has a
16MHz ARM7tdmi RISC processor. 32-bit but it can handle 16-bit
instructions in a mode that resembles "bytecode" (a 32-bit instruction
is executed using a 16-bit instruction). I got a feeling that the GBA
would need a FPU.
