There is a ladspa plugin doing that and it's made available by ladspa-karaoke
element (plugins-good). However, I didn't manage to build a working pipeline
using it...

gst-launch --gst-debug-level=2 filesrc location=song.mp3 ! decodebin !
audioconvert ! ladspa-karaoke ! audioconvert ! alsasink

loops with WARN message (no sound produced):

gst-dsp gstsignalprocessor.c:585:gst_signal_processor_pen_buffer: Pad
ladspa-karaoke0:Right-in already has penned buffer
0:00:04.664787000  5522 0x8082fa0 WARN   

then stops after a while.
