...D_POINT (for win32). The port is not complete, but most of the floating-point operations have been converted. Please give it a try and report any difference with previous versions (both for float and fixed-point).

Hi, I uploaded a pre-release of beta3 for which I'd like to get feedback. There are some new features like a new "ultra-wideband" mode for 32 kHz operation (up to 48 kHz) and a (intensity) stereo mode. You can get the source at: http://www.speex.org/download/Speex-1.0beta3cvs.tar.gz So please test that code and report any bug or inconsistency you may find. Jean-Marc -- Jean-Marc Valin, M.Sc...

Maybe this is plain stupid or off topic. Could an atleast working fixed-point implementation of Speex be made by using a C++ "faked float" class with overloaded operators? Don't know if this is a common way to solve stuff like this, but my guess is that it would work. //Best Regards, Jonas Tärnström. <p>> > So just how much work are we talking about, here, to convert to fixed- > point? > &g...

I was wondering if the developers were using anything to "objectively" test the quality of the speex vocoder. For instance PSQM or one of the many derivatives.

Hi, In view of the problems I was having with DomU network timeout after a live migration (I posted that problems here a while ago but never got anything except from private emails) I finally updated my Debian/Squeeze Dom0s last night to a new kernel, from 2.6.32-23 to 2.6.32-26. Now live migration just hangs...Any ideas?

...Win64. OK, so here's a first start. I've translated to intrinsics the asm I sent 1-2 days ago. The result is about 5% slower than the pure asm approach, so it's not too bad (SSE asm is 2x faster than x87). Note that unlike the previous version which had a kludge to work with order 8 (required for wideband), this version only works with order 10, so it will only work for narrowband. <p>void filter_mem2(float *x, float *_num, float *_den, float *y, int N, int ord, float *_mem) { __m128 num[3], den[3], mem[3]; int i; /* Copy numerator, denominator and memory to aligned...

...e also improvements in the packet concealment code and the VAD (Voice Activity Detection). It's also possible to have the VAD without VBR, so that Speex does comfort noise generation during silence, but otherwise constant bit-rate.
