Is Moode Audio a Real Time Kernel? I cannot find in the web site.

No, it isn't.

Thanks. As I know, there was a real time kernel in the previous version, something like ver.3.8. Why there is not now?

The RT kernel has been 'discontinued' because the creator (not Tim Curtis) has dropped the support long time ago. If you are looking for sound tweaks check this thread:

There is a fairly significant performance penalty derived from making the entire kernel pre-emptable and given that as of the last few versions (may be .22+, there’s a bluetooth conflict that keeps the older version the default) mpd utilizes real-time threads on timing critical tasks I’m not sure there’s any actual benefit. I might try compiling an rt-kernel when I get my pi4 but it would just be for personal use - even if a rt kernel was available it would potentially introduce a lot of support issues and Tim is already overworked. Here’s some reading material if you’re interested...
