equalizer-10bands

The 10 band equalizer element allows to change the gain of 10 equally distributed frequency bands between 30 Hz and 15 kHz.

Example launch line

 gst-launch-1.0 filesrc location=song.ogg ! oggdemux ! vorbisdec ! audioconvert ! equalizer-10bands band2=3.0 ! alsasink

This raises the volume of the 3rd band which is at 119 Hz by 3 db.
