An Open source phone based on Speex
Hi Farhan, What is the purpose of the protocol? Just to be a binary form a SIP? I mean conferencing, PTT, chat we have in h.323, sip, jingle, iax? What is the reason for a new one? The NAT traversal has been fixed for a while for all those protocols also. Diana farhan@phonestack.com wrote: > Dear All, > > I have finished documenting my Lightweight Telephony Protocol.

Symbian port
A couple of things to be noted on the symbian port. 1. the spokn.mmp file is missing window.c, please add that. 2. smallft.c is not required. it has global data that prevents compilation on symbian. 3. lbr_48k_tabels.c has a global variable called dummy_epic_48k_variable on line 37. this has to be commneted out too. 4. check that all tables are declared const. i will shortly post the symbian

An Open source phone based on Speex
Dear All, I have finished documenting my Lightweight Telephony Protocol. It is now availalbe on www.lightweighttelephony.org. I invite you all to use the simple command line client (so that you can script it anyway) that works with Speex codec (Create your userid on spokn.com). The site may not render properly on some browsers, I will fix it in the coming week. This protocol is simple and

Mixing Codebook?
heh...:) maybe I?ll just answer "the number is 42". ;) well... some guys did mixing using *G.722 *encoded frames... maybe we could ask them: 8P http://ieeexplore.ieee.org/Xplore/login.jsp?url=/iel5/4054516/4054517/04054870.pdf?isnumber=4054517&prod=CNF&arnumber=4054870&arSt=2045&ared=2048&arAuthor=G.+Agnello%3B+R.+M.+Dansereau and a little off-topic, but fun for

Divided by Zero Error Speex-dev Digest, Vol 34, Issue 12
Hi, I am getting the same problem of divided by zero while decoding in the function multicomb(). I am using fixed point speex code. Can anybody please tell me the solution for it. -----Original Message----- From: speex-dev-bounces@xiph.org [mailto:speex-dev-bounces@xiph.org] On Behalf Of speex-dev-request@xiph.org Sent: Tuesday, March 13, 2007 12:30 AM To: speex-dev@xiph.org Subject: Speex-dev

SPEEX on iPhone ?
Hello Ashhar, thanks for your reply, but i'm a bit surprised. 1- Does it mean that it is possible to make a Real Time Encoding/Decoding with SPEEX on iPhone ? 2- What parameters have been used (QUALITY, SAMPLING_RATE, BITRATE) ? and what kind of CPU load do they measure for that ? Thanks by advance, Vincent ----- Original Message ----- From: "Ashhar Farhan" <farhan at

SPEEX on iPhone ?
ok, interesting ! Do you know how much CPU it takes for a real time encoding/decoding ? it's more around 20% or 80% instead ? Do you know if it works for 44100 Hz / 32kbps / Quality =8 ? thanks again.

Windows Mobile build, memory allocation
I have sent the visual studio project files that compile the speex client to jean-marc directly (as an attachment), sometime this week, I will also upload the binary builds of static library files to my site www.phonestack.com. I am porting our LTP (lightweight telephony protocol) to some embedded systems. I require to run speex in an environment that doesn't support memory allocations. How

libspeex for other platforms
wouldn't it be a good idea to have the libraray available as a binary for non-PC platforms like the PocketPC, Symbian and Mac? i am suggesting this as it will allow the developers to go ahead and program to an interface while the development continues. there are builds for symbian, pocket pc and linux already in the tar ball. putting their binaries on the download section will probably

bad VAD in preprocessor of version 1.2beta1
Hello, first of all, sorry for the joke in the subject ;-) I have successfully update the speex library my software was using from 1.1.12 to 1.2beta1 (1.1.13). It is a VoIP software, where i set preprocessor VAD on and use the result of speex_preprocess() to determine if there is voice activity. I must say that it works fine...since i have update to the new version. Ive been testing, and

SPEEX on iPhone ?
I can confirm that it will run in real time on iPhone if you compile with FIXED_POINT defined; it will also run in real time if you have FLOATING_POINT defined and disable 'Compile for Thumb' in the target's build settings in xcode. Wideband works too. Cheers, Dave

SPEEX on iPhone ?
hello, i 've already used SPEEX in a protoype of voip application (on VC 6) and i must says that it works well, the sound is good, and the object works well with multi-instances. But now i'm wondering if it's possible to port the SPEEX encoder (and decoder process) on iPhone ? Does someone tried to do that ? Do you think it is possible or completly over the capabilities of the ARM

Palm OS port
hello all, At my workplace, our colleague Mukesh has just completed a port of speex 1.2.1 to Palm OS. He had to write a couple of mathlib functions, but the trunk remains unchanged. It works quite well, I was wondering if there will be any interest in this port in the distribution. - farhan

Playing captured speex frames
Hi, Searched far and wide for a solution to this problem but couldn't find anything. I'm debugging a VoIP application that uses Speex and need to playback the raw speex frames to verify the quality. Wireshark helped me save the RTP payloads into a file but unfortunately, the speexdec utility seems to be wanting a valid header at the start of the file without which it reports an error.

SPEEX on iPhone ?
Why don't you just try it? From what others have been reporting, it shouldn't take you long to get it running. You can use speexenc and speexdec for testing.

Trying to build ISOLinux Minimal CD
Okay.. I'm pulling out my hair, not having much luck trying to get ISOLinux (syslinux) running on my IBM x345 Server... I want to put my boot (syslinux) and root files (lib etc for modules) on the CDROM and just boot off of it to use PartImage... Not having much luck though.. For testing purposes I'm using the boot floopy I created using "The Linux Bootdisk HOWTO" and it
