Description Wellington Wallace 2017-05-16 21:57:19 UTC 
When I send a 59 Hz test signal to the equalizer its amplitude increases when I reduce band0 gain. I could reproduce this with the following commands:

gst-launch-1.0 audiotestsrc freq=59 ! equalizer-10bands band0=12 ! pulsesink

gst-launch-1.0 audiotestsrc freq=59 ! equalizer-10bands band0=-24 ! pulsesink

I can hear a louder sound with the second command. When the test signal has a frequency of 29 Hz the sound amplitude decreases when band0 gain is reduced as I would expect. So it has something to do with the overlap between band0 and band1.

I am using gstreamer 1.12.0 on Arch Linux.
