Avoid redundant LPC coefficient rescaling to Q12 to preserve precision
# Basic info <!--- Add commit SHA used to reproduce--> - Float reference: - Encoder (float): - Decoder (float): - Fixed point: - Encoder (fixed): 1c5efba77 - Decoder (fixed): # Bug description In the encoder, LPC filter coefficients are repeatedly rescaled to Q12 format, even though the sub-functions already handle different scaling internally. This redundant rescaling introduces unnecessary complexity and results in a loss of precision. # Ways to reproduce Box folder: ...\\Box_EXTERNAL_IVAS_BASOP_VERIFICATION\\issues\\issue-xxxx <!--Commandline or script--> ```bash ``` <!--- Below are labels that will be added but are not shown in description.
