[Speex-dev] Buffer size/rate woes

Hi All, I am trying to get speex working on the Mac and am running  
into issues.  I got the examples working, but am now trying to make  
speex, which expects 8000 Hz and 160 samples per buffer (320 bytes  
per buffer), work with the Mac's built-in audio recording, which uses  
either 11025, 22050, or 44100 Hz and 1024 samples per buffer (2048  
bytes per buffer).

I just need to know if there is a way to make speex run at say 11025  
Hz with maybe 512 (or other power of 2) samples per buffer.   
Otherwise there is going to be a lot of code handling remainders for  
each buffer and downsampling.

Also, does speex use a timer of any kind?  Or does it just process  
blocks as they are given?  I just mean for general encoding, not  
echoes, etc.
