That's true I'm trying to build it to use in android I used the -DOUTSIDE_SPEEX. and i get speex_resampler.h:51:2: error: #error "Please define RANDOM_PREFIX (above) to something specific to your project to prevent symbol name clashes" 2013/10/28 Gregory Maxwell <gmaxwell at gmail.com> > On Mon, Oct 28, 2013 at 11:26 AM, Antonio Juan <anquegi at gmail.com> wrote: > &gt...

Hi and thanks for your interest! this is the error, i need to add the speex folder and a path to the .h file and it works Compile thumb : opus-proj <= audio-in.c In file included from jni/../../opus-tools-0.1.7/src/audio-in.c:74:0: proj/../../opus-tools-0.1.7/src/speex_resampler.h:90:32: fatal error: speex/speex_types.h: No such file or directory compilation terminated. make: *** [/opus-tools-0.1.7/src/audio-in.o] Error 1 but then i have this error: error: undefined reference to 'opus_multistream_surround_encoder_create', this I think that is for I'm not us...

I recently stumbled upon <speex/speex_resampler.h> and made a chain of discoveries: - "http://speex.org/downloads" some links are broken ("rarewares" and git) - there is some (minor) development (whitespace and more) of the "dead" Speex codec ... will there be a release?

Dear Nikos, thanks! But you use Opus only for resampling, not for entirely replacing Speex, don't you? Greetings!

...not using Opus at all. I'm just including its resampler in my own sources. It's not even a DLL; it's directly compiled together with the rest of my code. You need these sources from the opus-tools package (http://www.opus-codec.org/downloads/): arch.h resample.c resample_sse.h speex_resampler.h stack_alloc.h In your project file, define these macros: #define SPX_RESAMPLE_EXPORT #define OUTSIDE_SPEEX #define RANDOM_PREFIX NAME_OF_YOUR_SOFTWARE If your software is actually a library itself, you might to instead: #define SPX_RESAMPLE_EXPORT __declspec(dllexport) or whate...

Thanks for your help, I will follow that, so in order to sum up I need: - libopus 1.0.3 compiled as static or shared library - libogg 1.3.1 compiled as static or shared library - opus-tools 0.1.7 and then follow the example in opus-tools opusenc.c to get things ready, because if I try to compile opus-tools, this ask for me for the speex library, and other things I think that that will we all.

hi on my device i can sample only at 32khz and want to use speex at 16khz so i need to down-convert the input signal by factor of 2. does anyone provide me a reference to some code that does that? are there any trick to do that? i tried to add to subsequent sample but the result was very bad. what are the requrment from a decimation filter for audio? thanks, nir -------------- next part

Attached is a snapshot of work-in-progress of a FFT based resampler. At the moment it works in floating point only, and only basic quality inspection has been done. Some benchmarks comparing the filter-based resampler at Q3 with the FFT resampler with overlap = in_len / 2, using 20ms chunks of data. (-O3 -ffast-math, FFTW3, gcc 4.3.0 on x86_64) 16=>48: 59us vs 19us 16=>44.1: 204us vs

Hi, Here's the (hopefully) final version of the resampler, now always using st->mem as the buffer area. It only allocates buffers on the stack when it's necesarry to convert the output between int and float. -------------- next part -------------- Index: include/speex/speex_resampler.h =================================================================== --- include/speex/speex_resampler.h (revision 14829) +++ include/speex/speex_resampler.h (working copy) @@ -73,6 +73,8 @@ #define speex_resampler_get_output_stride CAT_PREFIX(RANDOM_PREFIX,_resampler_get_output_stride) #defin...

Hi everyone, I recently began using libspeex 1.2 Beta 1 on Windows using MS Visual C++. I have gotten a decoder and an encoder to work fine from the excellent sample code posted at the website. But I face a problem. I am working on using Speex in a program to play and create audio books encoded using Speex (currently testing it only; for these tests, I do not use Ogg to save the encoded
