lossyWAV 1.2.0 is released.

lossyWAV is a near lossless audio processor which dynamically reduces the bitdepth of the signal on a block-by-block basis. Bitdepth reduction adds white noise to the processed output.

Changes from 1.1.0c:
  • Now compatible with FFTW (requires libfftw3-3.dll to exist on the path);
  • Spreading function changed;
  • Noise shaping now off by default - can be switched on to automatic or user specified value;
  • Introduction of --altpreset parameter which modifies internal presets and lowers upper frequency limit used in determining noise floor to 15.16kHz;
  • Major code cleanup.

How does the visualisation deal with the unprocessed WAV? Similarly, the decoded WAV from the lossyFLAC file?
