Please be aware that much of the software linked to or mentioned on this forum is niche and therefore infrequently downloaded. Lots of anti-virus scanners and so-called malware detectors like to flag infrequently downloaded software as bad until it is either downloaded enough times, or its developer actually bothers with getting each individual release allow listed by every single AV vendor. You can do many people a great favor when encountering such a "problem" example by submitting them to your AV vendor for examination. For almost everything on this forum, it is a false positive.

Frame Size in Speex

Hi,
Can someone please tell me how should I go about changing the frame size which is hardcoded to 160 for NB and WB and 320 for UWB.
For NB speech(8KHz) the framesize of 160 is 20ms frame but for WB and UWB its 10ms.
What are the parameters being affected by simply changing the framesize and sub-frame size in "modes.c"
How to change the buffer size and how its affected.
can we have a variable frame size implementation based on some voiced/unvoiced part?

I was also trying to add pitch prediction in WB/UWB part i.e. in high band coding, but found it really difficult to do it. Tell me if I can use the direct functions of pitch prediction in NB ? and HOW ?
