Replace call of celt_inner_prod_c() (step 2) Should call celt_inner_prod(). This requires the API change of celt_pitch_xcorr() by passing in "arch". We tested on x86 and arm, and got bit exact results as original. Change-Id: I606915da6a196f327ce81f4a5ae32811f4c1fabb Signed-off-by: Jean-Marc Valin <[email protected]>
