Speexdec plays ogg files. You can simply modify it to play your raw file or even rtp capture.

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

Speexdec is expecting the frames to be wrapped in an Ogg frame I believe. Since you have the raw data can't you just add the Ogg header information to this before passing it to Speexdec?

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.

what you need to do is this: take the wireshark raw dump, read each udp packet and write it back to another file. While writing back to the new file skip the sizeof udp header + rtp header. I can't recall how many bytes you need to skip, however, I suppose it would be in the range of 36 and 32 bytes. A five line perl script will do it. - farhan On 7/7/11, Vinod Panicker <vinod.p at

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

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.

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

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

hi, i am trying to compile a fixed point version of lipspeex on desktop windows environment. a short reason for the complicated story is that we need to keep the 'engine' part of our project same across the various ports of our voip project (blame the pointy haired boss). now, when i compile with FIXED_POINT defined in the Visual C++ 6.0, i get these errors:

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

i have been working on a voip client that goes head-to-head with skype in technological terms. for this, we used speex wide-band codec. without the denoiser or the pre-processor, i find that speex quality at 16 khz sampling, 16-bit samples (mono) to be clearly superior to anything that skype offers. even though, at the moment, i am not using packet loss compensation, i find that speex is

Hi, I am experiencing some unfortunate problems when encoding WAV files to spx using version 1.0.4. A "click" which is not present in the original WAV file is added to the end of the spx file. Is this a known problem, and if so, which version of the encoder should I switch to... and if I have to switch the encoder, will I also have to switch the version of the decoder? Sincerely,

Hi all, i'm going to try to create an app using libspeex (Speex 1.1.10) and Visual Studio and just have a few questions. First, what's the difference between libspeex and libspeex_dynamic? Do I need to include both projects in my new workspace? Next, how do I enable fixed_point using libspeex? Am I correct in assuming that an ARM processor would be able to record speech as speex files

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

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

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
