[speex-dev] Coredumps when --enable-sse is selected
> I've tried the same configure options on my system and it doesn't crash. > I have the same glibc and gcc 3.3.2 (can you see if a newer gcc works?).When I build it with gcc-3.3.3, the problem disappears. I guess the older gcc's XMM macros were buggy. Thanks for the suggestion.> Also, could you explore a bit with different options so we can narrow it > down a bit.Actually, the crash occurred with even very simple options. I'm now encoding the very same file which caused segfaults in the gcc-3.2.3-built binary. I would probably put a note (or modify the build script to detect/warn the user) about gcc-3.2 and --enable-sse. I suspect if we lookup the gcc bugbase, we'll see some changes made to the SSE intrinsics.

I get input from microphone, but the microphone's noise is so noticeable. How to avoid microphone noise? Should I buy another better microphone? What kind of microphone I need? How much is it? Or I could do something in the software, using speex functions? <p>--- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this list, send a message to 'speex-dev-request@xiph.org' containing only the word 'unsubscribe' in the body.

What kind of microphone I need? How > much is it?You have three things that contribute to the noise: 1) The microphone 2) The soundcard 3) The environment (don't underestimate that one)> Or I could do something in the software, using speex functions?For stationary noise, there's now a denoiser in 1.1.x (unstable). You can use it with the --denoise option to speexenc and the API is in speex_preprocess.h Jean-Marc -- Jean-Marc Valin http://www.xiph.org/~jm/ LABORIUS Université de Sherbrooke, Québec, Canada -------------- next part -------------- A non-text attachment was scrubbed...
