[SUGGESTION] near-lossless audio pre-processor

Description

lossyWAV is a near lossless audio processor which dynamically reduces the bitdepth of the signal on a block-by-block basis. Bitdepth reduction adds noise to the processed output. The added noise is adaptively shaped by default and can alternatively be fixed noise shaped or white noise depending on command line parameters. When lossyWAV processed output is compressed with certain lossless codecs (FLAC, Wavpack, Tak, LPAC, MPEG-4 ALS and WMA-Lossless) the bitrate of the output file is significantly* reduced compared to the lossless original.

The source code of recently released version 1.4 has been completely converted from Delphi to C++, allowing the POSIX port:
