I came across SoundTouch when I was using Audacity. I am not entirely

That's really positive ! Keep-up the good work and let us know ! :)

Is it a Rockbox plugin, or did you need to hack the core ? I would
love to see the code, as I need to make progress on codec playback
from a plugin.

I don't see Daisy playback as a core feature of Rockbox. A plugin
application (configured as a viewer for NCC or NCX navigation files)
would do just fine in my opinion. As a standalone application, it
would be easier to maintain and could be updated regularly without
any impact on the core.
