How much memory reduction are you after? There's lots of stuff you can delete, starting with defining DISABLE_VBR, DISABLE_WIDEBAND and DISABLE_FLOAT_API. From there, you can delete all the *table.c files except for exc_10_32_table.c, gain_table_lbr.c and lsp_tables_nb.c. In libspeexdsp, you can pretty much delete everything (preprocessor, jitter buffer, resampler, ...) but mdf.c Jean-Marc

hi Jean-Marc, I just updated from svn and it looks like there are some errors in the speex.mmp file. the filters.c is duplicated, and the fft/kiss.c files are still missing.. /alfred Jean-Marc Valin wrote: > Applied in svn.

Hi everyone, I'm currently looking into using speex in an embedded project using an ST ARM-device (STR9 family) just with internal memory (96kbyte) and no O/S. Does anyone know if the optimizations included in the code for ARMv4 and ARMv5e are appliable to this device? I would also need to strip down libspeex pretty hard to fit into the available memory. I just want to use a fixed bitrate

Hello to everyone! During building speex library for Symbian OS I encountered some problems. All thess problems can be solved by modifying the speex sources. I don't have access to SVN repository of speex, so I will just describe the changes to be done: 1) mmp file in symbian derictory misses windows.c sources. You need to add this string into speex.mmp: SOURCES windows.c 2) Symbian OS

Hi everyone, Just to let you know that version 1.2beta3 is out. The main change is the split into libspeex and libspeexdsp. Basically, libspeex keeps the codec (just like it was for 1.0.x) and libspeexdsp has all the new components. Other changes include a new jitter buffer algorithm and resampler improvements/fixes. This is also the first release where libspeex can be built without any floating

Hi Jean-Marc, I have the following problem when cross-building speex 1.1.7 with MaverickCrunch support. To add this support I had to define CPPFLAGS as follows: export CPPFLAGS='-mcpu=ep9312 -mfix-crunch-d1' but it seems libtool does not like it, while the object files are compiled fine: ... arm-linux-gcc -DHAVE_CONFIG_H -I. -I. -I.. -I../include

This patch updates the symbian build files to latest svn trunk, and also adds a new makefile for speexdsp. Signed-off-by: Alfred E.

Hi all, I am a newbie here and just started using speex in our lab. During compiling my voice application with windows-compiled version provided today, I am getting "unresolved external symbol _speex_wb_mode". I am probably missing some setting with VS6.0 linker... (I am a bit new to windows too) If anyone could point it out, I would appreciate it. - Tim -----Original Message-----

Hi All, We are using speex for linphone in blackfin fixed point platform. The speex version we are using is svn-14525. If we don't disable vbr by "--disable-vbr", the sound quality will be very bad in linphone. But if we disable it, sound will be perfect. I noticed in the speex.org, there is a comment like this: > >Speex 1.2beta3 is out >December 11, 2007 >The most

Hi Mark, Code below: int16_t* samples; int16_t* fbSilenceFrame; void *fSpeexState; float eng(0.f); int speexFrameSize(0); speex_encoder_ctl(speexState, SPEEX_GET_FRAME_SIZE, &speexFrameSize); for (int i = 0; i < speexFrameSize; i++) { eng += samples[i] * samples[i]; } if (eng / speexFrameSize < 3.f) { memcpy(samples, silenceFrame, speexFrameSize * sizeof(int16_t)); } where

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Could anyone tell me how libspeex_armce.lib Speex 1.1.6 was compiled? (http://www.speex.org/download/libspeex_armce.lib ) Does it exist some modified fixed_arm5e.h for Microsoft EVC arm-asm compiler? or the inline assemlby was compiled with GCC and linked through EVC LINK.exe? if the latter was done could I know how to link with EVC ?
