Would it help if I scale the input wav data before encoding to spx? One interesting thing is if I encode the same wav file to spx(or decode the same spx file to wav ) on Windows platform, then there is no such big clicking noise, samething is true if I use floating_point speex library to encode/decode on WM2003. Problem happens only on WM2003 using FIXED_POINT library. Thanks Yanxin -----

I am running speex 1.2beta1 on WM2003 using FIXED_POINT option, I got big clicking noise during encoding or decoding randomly, I got more noise if I spoke louder or made the MIC sensitivity higher, for example, when I encode the wav file to spx file, the original saved wav file does not have such noise, the noise is added only after it's converted to spx format. The floating point version of

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 Carl, Can you send me libspeex compilated in eVC. And can you describe where and how set the FIXED_POINT flag in eVC. Thanks you. Regards.

Hi there. We're trying to build a speex decoder for Palm OS (i.e. ARM7). No major problems porting thus far, but when compiling the speex modules with -DFIXED_POINT all the silent parts of the output are replaced with what sounds like high-power white noise. The spoken parts sound great, but all the silent parts in between speaking just sounds like white noise. We're using speex 1.1.6,

Hi All, i have configured speex1.2rc1 for xscale-elf (ARM architecture) ,then executed MAKE and MAKE INSTALL. so, i obtained libspeex.a in the /usr/local/lib with libogg.a compiled as well. but i when i link the library to my program (by adding LDFLAGS += -lspeex -lm ), and try to compile, i get this error: /usr/lib/gcc/xscale-elf/3.4.3/../../../../xscale-elf/bin/ld: cannot find -lspeex collect2:

Thanks for the reply, i added (LDFLAGS += -L/usr/local/lib -lspeex -lm) to Makefilebut the error is still appearing ! /tmp/ccDFH8gi.o(.text+0x179c): In function `main': : undefined reference to `BlinkC$speex_bits_init' collect2: ld returned 1 exit status make: *** [exe0] Error 1 i am trying to guess what is missed to correctly link to the lib .Do you have suggestions? Regards,

It seems that with the file I posted, the decode noise persists all the way back to 1.1.1, when using --enable-fixed-point. When we configure with --enable-fixed-point-debug, the decode seems to be correct, even on 1.1.6. Hope this helps, and thanks for your time!

It's not really documented, but when you compile with --enable-sse, you need to add -march=pentium3 to the compile switches. That's actually a gcc requirement.

Hi, I'm evaluating the libspeex library for usage in an embedded platform based on an ARM7 TDMI micro (the ubiquitous Atmel AT91SAM7S). In details, I'm trying to use libspeex to encode the audio stream coming into the micro from an I2S channel and saving the encoded audio to an SD card (currently in binary format just to test it decoded back to the I2S channel from the saved file), but

Hi I downloaded Speex 1.0.1 and I am not able to compile the source files (examples) speexenc.c and speexdec.c What are the libraries needed to run the above examples ? I am using VC++ 6.0 /Win XP. I addes ogg.lib and libspeex.lib files. do I need to any more lib files ? Please advise. Regards Ravi. <p>--------------------------------- Do you Yahoo!? SBC Yahoo! DSL - Now only $29.95

This is a really good point, and definitely a recurring theme on this mailing list. :) I wonder, what are some better options for handling this issue, other than to keep saying "just use 8/16/32kHz"? - Extend Speex to support other sample rates (seems unlikely..?) - Integrate a resampling algorithm into libspeex - Maintain a list of recommended resampling libraries that work well

Hi, I am working with libspeex api. I would like compare the size of speex file encoded with libspeex and the size of speex file encoded with speexenc. For example, I encode with speexenc (narrowband, quality 1) a wav file of 1.43 MB (17 seconds) output a spx file weight 21KB, for other hand I encode with libspeex the same wav file with same characteristics in arm processor, pocket pc and the

Both output files was created using same program by compressing from wav to speex, then decompressing from speex to wav (using speex_encode_int and speex_decode_int). Only difference was used speex

Sorry, been busy with maintenance on Valin 2.0 and 3.0 :-) Just applied your fix to the assembly. Can you confirm it works
