    dca: change the core to work with integer coefficients. · aebf0707
    Alexandra Hájková authored
    The DCA core decoder converts integer coefficients read from the
    bitstream to floats just after reading them (along with dequantization).
    All the other steps of the audio reconstruction are done with floats
    which makes the output for the DTS lossless extension (XLL)
    actually lossy.
    This patch changes the DCA core to work with integer coefficients
    until QMF. At this point the integer coefficients are converted to floats.
    The coefficients for the LFE channel (lfe_data) are not touched.
    This is the first step for the really lossless XLL decoding.
