Fo this portion of code in the psydecay_init( ) of CELT (psy.c) :
decayR[i]=Q15ONE*power(0.1f,deriv) /commented: decay corresponding to -10
decayL[i]=Q15ONE*power(0.0031623f,deriv) /commented: decay corresponding to
Why 0.1 (or 0.0031623) is being raised to the power of deriv? what is the
meaning of this? why 0.1(or 0.0031623) not other number? is it related to
(-10, -25 respectively) how we get it?!
Why Q15ONE (which is either 32767 or 1.0f, as I have observed it in the code) is
being multiplyied by the term also?
Thank you for your attention,
