[Speex-dev] Speex on TI DSP 5505

Hi 

 

When we run the profiler these 3 functions take more than 8500 cycles.

 

split_cb_search_shape_sign_N1() 22782
pitch_search_3tap() 19208
lpc_to_lsp() 16007
 
So can I configure these in a different way so it takes less cycles.
I do not need very high sound quality
 
Thanks for your time

Warm Regards 
Saju
