I've been using musepack with xlevel and I am glad that the best lossy audio format can handle internal clipping in all by the most terrible cases. However, I'm curious about other formats as well. Is internal clipping a problem with MP3's and OGG's? Do either of these formats offer ways to combat it effectively like xlevel does with Musepack?

Internal clipping is an MPC bug. The other formats do not suffer from it.

And one which should be fixed in SV8 if I understand correctly. I don't know if the current pseudo-SV8 have the problem or not though..

Frank Klemm said that this is not a bug, it's a design flaw from the early stages of MP+, and that a "clean" solution takes 5 minutes to program, but would break compatibility with SV7 (thus the "hotfix" with --xlevel).

The SV8 test versions are already fixed. From the MPC 1.91z changelog:

7 bit scale factors (no internal clippings anymore) for 190 dB possible dynamics.
