You can clearly see that vorbis-tools is in the dependencies, and attempting to install:

jaska@bowmore:~$ sudo aptitude install ripperx

The following NEW packages will be automatically installed:

The following NEW packages will be installed:
  libid3-3.8.3c2a ripperx vorbis-tools

...suggests that it will actually install encoders. The fact that I used aptitude is irrelevant when it comes to direct dependencies.
