Hi, I have an application for Windows that encodes speex into a QT Movie. This all work just fine. I am porting it to Windows Mobile and read to use the FIXED_POINT define for better performance. I decided to test FIXED_POINT on Windows and noticed that with FIXED_POINT the audio was garbled where before it was fine without FIXED_POINT defined. Is there any known issues or anything I must do when FIXED_POINT is defined? Cheers, - Keith

Hi, Should FIXED_POINT work fine on WIN32 or is it just for CE, Symbian and TI? - Keith ----- Original Message ----- From: "Jean-Marc Valin" <jean-marc.valin@usherbrooke.ca> To: "Keith Gurganus" <kgurganus@zygodigital.com> Cc: <speex-dev@xiph.org> Sent: Friday, October 19, 2007 10...

Fixed-point should work on any platform that can multiply two 16-bit integers, including Win32 (that is, until MS releases it's proprietary replacement for integers).

Actually opus-tools-0.2 has the same issue. Sincerely Forrest Zhang -------------- next part -------------- Add "#define FIXED_POINT 1" into the top of resample.c, outputs of resample are all zeros.

Hello - We are building Speex 1.2rc1 on Symbian/S60 using the GNU csl-arm-2005Q1C tool chain provided in the S60 SDK. We build with the supplied config.h and define FIXED_POINT to 1. We found that the encoded audio is "garbled" when we build with GCC -O1 or -O2 optimization level with fixed point enabled. But if fixed point is enabled and no GCC optimization level is specified, the encoded audio is correct. The encoded audio is also correct with fixed poin...

I have build celt with FIXED_POINT option (latest 0.6.1 as well as from the git repo) on windows. However I am not getting a valid output (all samples are saturated) when I try to decode with this version. The input file was encoded with the same fixed point version. Does fixed point version work at all? Following are the comma...

..._org.wav is original file. 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 library. krwawa_fixed.wav was created by libspeex compiled with defined FIXED_POINT krwawa_float.wav was created without FIXED_POINT. When samples values do not exceed (-32000;32000) eveything is ok. Testing platform was Pocket PC, with ARM cpu, libspeex compiled in MsEVC++4.

Hi, I've recently successful built and run CELT under Windows using "testcelt.c" example file. Since I'm about to port it on a embedded platform i activated the FIXED_POINT #define. I included fixed_generic.h and without other changes to the code i tried to encode and decode the same file i previously used. The output though is completely saturated i.e. it jumps from -32768 to +32767. I then tried decoding an encoded in floating point mode file with a fixed point d...

Hi all, i'm going to try to create an app using libspeex (Speex 1.1.10) and Visual Studio and just have a few questions. First, what's the difference between libspeex and libspeex_dynamic? Do I need to include both projects in my new workspace? Next, how do I enable fixed_point using libspeex? Am I correct in assuming that an ARM processor would be able to record speech as speex files in real-time with fixed_point enabled? (I think I read this in a forum somewhere...) Finally, forgive me for asking an *obvious* question if it is... but libspeex (together with libogg) was...

Hello, I received feedback from engineers working on NE10 [1] that it would be better to use NE10 [1] for FFT optimizations for opus use cases. However, these FFT patches are currently in review and haven't been integrated into NE10 yet. While the FFT functions in NE10 are getting baked, I wanted to optimize the celt_pitch_xcorr (floating point only) and use it to introduce ARM NEON
