What is the best format settings to store a physical music?
I did look at Flac but the data is almost the same size as the uncompressed Wav and none of my devices or self hosted services seem designed to play flac files. Everything gets converted.
What are people using?
If flac is almost the same as uncompressed, I think something is wrong.
OP must have it set to the lowest compression level. All levels are lossless, but higher compression levels are smaller, at the expense of increased encoding time. Should be half the size or less in general.
