Default Simpw: output filter resonance reduction

This is a SMPS with output filter resonance reduction,it's designed during the ABU robocon 2004 projects, and was open to public since then on our Chinese site.

NOTE:the output stage is designed as a SMPS,not class D amp!

I post here to have this scheme discussed and tested for audio applications -- I'm mainly designing motor control systems before,without any audio amplifier experiences.So my ears is not sensitive enough to judge if a amplifier produces a good sound.

Please point it out,if this touchs any existing patent.Thanks.
