GObject +----GInitiallyUnowned +----GstObject +----GstElement +----GstBaseTransform +----GstAudioFilter +----GstAudioInvert
Swaps upper and lower half of audio samples. Mixing an inverted sample on top of the original with a slight delay can produce effects that sound like resonance. Creating a stereo sample from a mono source, with one channel inverted produces wide-stereo sounds.
