Comment (by gjdfgh):
> I meant flaCCL have better compression in comparison with libflac.
Besides better compression, it's ~7 times faster than libflac, since both
openCL and CUDA increases encoding considerably.
This is questionable and might just be due to different settings. Also
someone else said libflac got some SIMD optimizations recently.
>at maximum compression level.
These things tend to get exponentially slower at higher levels for very
little gain. Meaning you're trading minutes for some kilobytes in
compression efficiency increase.
