; Presearch tries to quantize by using the property Sum( abs(x[i]*K)/Sx ) = K.
; If we use truncation for the division result then the integer Sum would be <= K.
; By using nearest rounding we get closer approximation, but
; we could also get more than K pulses and we have to remove the extra ones.
; This method is the main improvement of the ffmpeg C function over the Opus original.
