Merge remote-tracking branch 'shariman/wmall'

* shariman/wmall:
  Perform dequantization of channel coefficients
  Perform inverse inter-channel decorrelation and ac-filter
  Implement revert_inter_ch_decorr() and revert_acfilter()
  Enable inverse-MCLMS filter
  Fix inverse-MCLMS filtering routines
  Do not update buffers in case no speed change is necessary
  Use int for channel_coeffs instead of int16_t
