equalizer-3bands

The 3-band equalizer element allows to change the gain of a low frequency, medium frequency and high frequency band.

Example launch line

 gst-launch-1.0 filesrc location=song.ogg ! oggdemux ! vorbisdec ! audioconvert ! equalizer-3bands band1=6.0 ! alsasink

This raises the volume of the 2nd band, which is at 1110 Hz, by 6 db.
