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 build file (speex.mmp) t...

Hi, Sorry if this a repost but I want to create the smallest Speex library possible to be put in TI's TMS320 DSP. I'm only interested in one configuration: 5.97 Kbps narrowband. What part of source code can I remove? Currently, when I compiled the version 1.1.12 libspeex.a library with the TI TMS320 and Fixed-Integer options, I get around 522Kb. I would like to reduce it to as small

...DC__ # include <malloc.h> # else # define alloca(x) (_alloca(x)) # endif # define rint(x) (floor((x)+0.5)) #endif #endif Sqrt domain errors still occur when encoding a full range pure sine wave. Is anyone else seeing that problem? An exception occasionally occurs on line 1251 of smallft.c: if(l->trigcache)free(l->trigcache); when calling ov_clear for vorbisfile. It seems to occur for the new higher bitrate files. The command line tools do not seem to cause the exception. Using old beta 1 code works fine.

...nables FFTW3 to be used by libspeexdsp. Using SSE, the FFT code is more than twice as fast, and it's 50% faster even without SSE. To enable the library, you'll need to call configure with '--with-gpl-fftw3'. Based on the benchmarking we did, this also changes the default FFT to smallft for floating point implementations when not using FFTW3.

Hi, I have included the oggvorbis encoding and playback stuff in the Linux-Mandrake distro back in August 2000. At that time I put the "nightly CVS" version, which worked just fine. Then on Mon Nov 27 I noticed some RPM's labelled "1.0beta3" on the website so I upgraded with these ones. Since then we have had some serious problems in encoding: approx 20% of the WAV
