My question is not close related to the development but as i see the creator of WavPack is also reading this topic so maybe this is the best way to ask you both.
why not just use WavPack hybrid mode?
it sounds like a good question for the fb2k developer(s) - "can you support lossyFLAC+correction files please?"
White noise getting applied "pretty much evenly across the spectrum" just isn't good enough
With adaptive noise shaping the added noise is reduced in the audible range and enhanced above the audible range.
Don't like the --altpreset switch being eliminated. Also don't like the "new & improved" (AKA "Slow") adaptive noise shaping method.
