...ows 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: e:\phonestack\engine\speex\cb_search.c(185) : warning C4133: 'function' : incompatible types - from 'short *' to 'float *' e:\phonestack\engine\speex\nb_celp.c(875) : warning C4761: integral size mismatch in argument; conversion supplied e:\phonestack\engine\speex\nb_celp.c(1603) : wa...

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 difficult is it to convert speex_encoder_init and speex_decoder_init to use preallocated memory buffers (presumably passed...

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.

...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 ?

..., and after some days of trying to fix the problems and following the help provided from speex-dev@xiph.org i've reached to the conclusion that the libspeex.lib was compiled with a different type of compiler.Later i've found the libspeex_arm.lib for Pocket PC 2002 on this site : http://www.phonestack.com/software.html.I had no more linker problems and the functions seem to work (i assume) , but the encoding function creates the "compressed_file.spcx" (but not corectly , i know this because i've tested the size of the file in comparisson with what i got by using speexenc.exe) and...

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

ivo and others, i am having a very interesting exchange about the LTP with diana. I took it offline from speex-dev as it would not interest everyone here. I will reply to ivo separately. I have also setup a mailing list on http://tech.groups.yahoo.com/group/ltpdiscuss/ if anybody is interested. but the key issues that the solves is that: 1. support p2p community based telephony that can punch
