How does sonic compare to libsoundtouch which is already in Debian and other distributions?
SoundTouch is good for music, and bad for speech. I added a couple samples for comparison on the new sonic home page at:
http://vinux-project.org/sonic
Here's direct links to the samples:

There are good reasons to want to speed up music, and SoundTouch is quite handy for that. It absolutely belongs in Audacity, for example. However, I see little need to speed up music in an MP3 player. Users almost always want to listen to music at the speed chosen by the artist.
On the other hand, speeding up podcasts and audio books is feature used by a lot of people. Sonic is a very simple library to enable this. In fact, only two files need to be added to a project: sonic.c and sonic.h. It has zero external library dependencies, and is optimized for ARM processors with no FPU.
