Dear @C.R.Helmrich, if you're about to abandon this project, be sure to roll out one last release that improves the sound as in that sample of yours (May, 2022). You see, a lot of hardware has FLAC support, including quite old players, so Exhale (which you mentioned above) is not an option there.

The difference in size between FSLAC -2 and -3 never ceases to amaze me. But the hand still reaches for -3, because its spectrogram is almost indistinguishable from the original, which welcomes further lossy compression for the portable player. Of course, the spectrogram is not everything, you need to check with your ears, but it would still be unpleasant to upgrade the hardware tomorrow and discover that the -2 collection has flaws. Curiously, achieving the same visual indistinguishability with Wavpack in hybrid mode is not easy, it stubbornly retains some content (quantization noise, I guess) in the upper segment.

@C.R.Helmrich Could you update it with FLAC 1.4.2 please?

Oh, @C.R.Helmrich, where are you? Boys and girls are hungry for an update to 1.4.3.
