Description

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.

Example launch line

gst-launch audiotestsrc wave=saw ! audioinvert invert=0.4 ! alsasink
gst-launch filesrc location="melo1.ogg" ! oggdemux ! vorbisdec ! audioconvert ! audioinvert invert=0.4 ! alsasink
gst-launch audiotestsrc wave=saw ! audioconvert ! audioinvert invert=0.4 ! audioconvert ! alsasink
