Hi all, I'm quite new to Speex and i'm tryng to do a porting of it for my pocketpc platform.... The encodig time seem to be too hight, i think something goes wrong putting --enable-fixed-point --enable-fixed-point-debug --enable-arm-asm in project setting of EVC++ 3.0 (i've got EVC++ 4.0 too) i do my test with an Ipaq 3850 (206 MHz Intel® Strong ARM 32-bit RISC Processor) running

Hi i'm developing a sort of VoIP application for my ipaq using speex... I'm still at beginning and i have many problems encoding and decoding my wav files....output is only noise! Why? I'm using Libspeex 1.1.3, Embedded VisualC++ 3.0, Ipaq 3850(206 MHz Intel® Strong ARM 32-bit RISC Processor) PocketPC 2002 (Windows CE 3.0). Libspeex is complied with the definition of

Hello Jean-Marc, I encoded a 143 kb file on both the desktop as well as the Pocket PC using the default settings/ Here are the results. Size : Desktop - 17.6 Kb, Pocket PC -17.1 kb (not much difference in size) Now when I try to decode the file encoded on the Pocket PC, I get a message "This doesn't look like a Speex file". However, when I decode the Pocket PC encoded file on

Hello Greg If money isn't a problem Intel has an optimized compiler for eVC and XScale processors http://www.intel.com/software/products/compilers/techtopics/PCA_Optimization_WP.pdf If you have any luck getting the eVC compiler closer to realtime I'd really like to know. I'm still far from realtime when using Speex 1.1.3 on a HP iPAQ (Intel pxa255). Best regards Bjoern D.

Hi, I encoded file in a ipaq 1940, pocket pc 2003, processor Samsung s3c241(similar to ARM), 266 Mhz. I would like to know your opinion for the quality output if this is right to entered parameters. File original: http://padawan.ing.puc.cl/chavezorig.wav File encoded: http://padawan.ing.puc.cl/chavezq1.wav The parameters for encoded are: state = speex_encoder_init(&speex_nb_mode); int tmp=0;

hello, I have recently compiled speexenc for WinCE/StrongARM SA-1110-processor. It seems to run with no errors, however the encoding time is very slow - 10 seconds of speech takes aprox 3 minutes to encode. Even though the target architecture is significantly less powerfull than a standard PC, I am trying to figure out why it is this slow. Does speex use floatpoint calculations? The input raw

Hmm, what these instructions do? (I know nothing about ARMs; I have some knowlege about x86 assemblers and programming). Cant we use pure standard C++ or Java? Does Speex work with fixedpoint math? (As far as I know Java on 6600 has no builtin floatingpoint, there is emulation class somewhere on the net, but it is probably painfully slow.) I do not know if this processor has builtin

Hi, Now that Speex is getting pretty stable, I have decided to make a fixed-point/integer port the #1 priority. At this point, I'm looking for help from people with prior fixed-point experience and/or a good signal processing background. Anyone would like to volunteer? I have already started the port by converting to int some of the most used functions. While this should only have a small

Thanks very much. You mean both encode and decode simulateusly (duplex)? Could you test the Java version (jspeex) on that iPaq too? (I do not have anything other than very fast PC, so I cant do this...) And, in phone, the mic can record not only the users speech but also voice from the other side (from speaker)... Does this make compression harder or the result worse? How can this impact

Is there a soft phone for PocketPC or iPaq? If not, is someone working on it? I will be more than willing to contribute my mite if needed. Thanks, -- sudhir

Hi Rodrigo, I'm Fabio and i'm in your identical situation, i need Speex to run on PocketPC in real time mode for my tesis. I've to develop a sort of VoIP apllication for pocketPC... I recently discover speex (Only yesterday i joined this mailing list....) and I'm doing many test using mostly VC++ 6.0 but only because i'm still undestandig speex... I did many works with EVC++

Hi all, I've created a Speex decoder for Pocket PC so that I can play Speex files from within my .NET CF app. But there has been a problem while playing the files on my Pocket PC. I encode a wav file on the desktop using Speexenc.exe (Speex- 1.1.5) and then copy this file to my Pocket PC where I playback using my decoder library. But the sound quality is extremely poor and completely

Target is Spv & Nokia phones ARM and also ipaq ARM. With the generic fixed point at complexity 0 I am still about 1.6x realtime for narrowband. The MS eVC compiler does not support inline assembler, only separate assembler functions. Does anyone have a feeling on whether a 2x speedup is possible if I hand tune a few functions? -greg. --- >8 ---- List archives:

Hello Cesar I'm using Speex on a PPC2002 and PPC2003 with no problems. For tune-up remember to define the FIXED_POINT macro in Project->Settings in eVC. With this setting you ought to be able to at least decode in realtime while using debug-mode. Kind regards Bjoern D.

Re: [speex-dev] Error in compiling Speexdec code (Speex-1.1.5 code)onWindows usingVC++6.0Actually one thing i should point out if you do decide to go this route.... currently my demuxer builds a seek table, which could potentially be a bit of a memory hog on a small device... though when i get around to adding the networking code, i will have to use my bisection seek code, so the use of the seek

Hi all, Can i use The denoise preprocess in my pocketpc (ARM XSCALE 400 Mhz)? It seen there is no a fixed point version...

Hi all, I've got a 400MHz XScale-PXA255 board, and I want to stream voice from it over a network connection at 28.8baud. This calls for a capable voice encoder which can encode at about 24kbps. I was damn happy when I found Speex and said goodbye to MP3 :) However, i'm still a long way from realtime encoding using speexenc, is this possible? Using the fixed point math option in
