If yes, does such a program already exist? (similar to mpc2sv8, the Musepack SV7 to SV8 converter) Motivation: I'm asking this because I have many gigabytes of MP2 files stored on my hard disks. These are captured DVB radio broadcasts in 320kbps 48kHz stereo MPEG-1 Layer II format. I would like to save some storage space here and hope that Musepack with its more efficient lossless coding method can produce smaller files than MP2.

But even if the entropy coding is better, I don't think you will be able to gain more than 20% of the file size. I don't know any program that do that (but I may be able to help you if you want to do it).
