You might not be doing anything wrong. Speex is stateful and can get into a bad state sometimes. It's happened to me too, but not recently. And I've seen such bugs reported on this list and fixed. I suggest several approaches to solving the problem: 1) Try compiling Speex without compiler optimizations and see if the problem still occurs. Most likely it will, but this is an

Hi, Basically, inner_prod() can and should be adapted to the architecture it will run on. It is not really sensitive to noise, so it's possible to tweak it a lot. Also, in the current code, I saturate it to +-16384, which is OK to prevent overflows. I'm not concerned with the case of a constant -16384 value because it can't really happen in practice (especially after filtering). BTW,

Hello, I am from a small Czech software company (circletech.net) working on software for mobile phones. We are currently starting a development of an Voice IP software, and consider using speex for voice compression and decompression. The software will be Symbian OS C++ program. Is there anyone who has actually used speex Symbian OS port for realtime voice compression and decompression on mobile
