Bug ID: 510397
Summary: Audio Equalizer (avfilter) may kill your ears when
ramping up Gain

Screenshot of the effect's settings.
SUMMARY
This really, really hurt my ears. I was using InEars(!) for monitoring and
ramped up Gain, unfortunately a bit too much apparently. The sound became
extremely shrill and loud. Ouch!!
>From now on I only have I keep my InEars unplugged from the ear, when using any
effect. :-/
Is there any reasonable setting, where a Gain above ~90 makes any sense? That's
roughly the point, where the beeping sound starts for me. The maximum is 600!
STEPS TO REPRODUCE
1. Drag in any video file with audio or any audio
2. Add the Audio Equalizer (avfilter) effect to the audio
3. Adjust the Gain and play back
OBSERVED RESULT
Be warned again, don't do that with InEars. At above a factor of 90 I hear a
shrill beeping, which becomes extremely loud when raising the gain a bit more.
EXPECTED RESULT
No ear damaging effects.
