Are files streamed in original quality? Hi-Res?

I just installed swing music and I like it so much! I searched for a while for good self-hosted streaming and it's awesome.

I wonder if files streamed in original quality?

I have an album with FLAC files in 24bit/95kHZ.

When I play it the Web UI sends request

What container mp3 mean? It's transcodes audio to mp3? Can I force uncompressed stream?
