    ac3enc: do not right-shift fixed-point coefficients in the final MDCT stage. · 323e6fea
    Justin authored
    This increases the accuracy of coefficients, leading to improved quality.
    Rescaling of the coefficients to full 25-bit accuracy is done rather than
    offsetting the exponent values. This requires coefficient scaling to be done
    before determining the rematrixing strategy. Also, the rematrixing strategy
    calculation must use 64-bit math to prevent overflow due to the higher
    precision coefficients.
