TPDF dither DSP that leaves digital silence untouched.


1.0.7 (2021-11-14):Fixed noise issue introduced in the previous version when target bitdepth was 8 bps or less. Signed signal was passed on as unsigned.
1.0.6 (2020-01-24):Bit depth truncation to 23 and 24 bits introduced very quiet artifacting (sub -144 dBFS). That is now fixed
1.0.5 (2018-01-06):No changes in functionality. Dynamic C runtime version for foobar2000 v1.4
1.0.4 (2017-01-26):Added option to disable high-pass filtering of the dither noise.
