General Audio / Re: How do you test SACD audio dynamic range?
Last post by soundping -I never would have thought of using Replaygain.
The compilles i did with GCC 13.2.0 should create the same files in size.I do indeed have fast-math enabled on both x64 compiles. I too recall a lame issue, I think with a particular Intel compiler option, but I don't recall which option, and it was in any case some many years ago.
It is only when i use AVX or fast-math that includes -funsafe-math-optimizations the output changes.
The rarewares x64 compile for example creates the same files as when i use fast-math.
I attach a compile that has both versions with exactly the same settings but fast-math if someone wants to check.
The question is if such optimization at some point changes the sound. I am no expert here but think to remember there once was a problem with a lame compile because of some compiler option.
