The code accumulates the raw mantissas while only using the exponent from the last iteration during the dB conversion, which can lead to an incorrect result when the exponents differ. ```bash *p_ild_new_fx = extract_l( L_shr( Mpy_32_16_1( L_add( BASOP_Util_Log2( *p_ild_new_fx ), L_add( 16 << Q25, L_shl( p_ild_new_e, 25 ) ) ), 24660 ), 15 ) ); ``` <!--- Below are labels that will be added but are not shown in description.
