Here are some proposals for the bass boost filter:
Boost Strength: adjust it in dB, is more understandable to adjust.
Maximun Boost:
- It would be good to change the second slider ("Then dropping to no boost at"), For outstanding values in octave / dB (6, 12, 18, Oct. 24 / dB)
Allow Harmonics:
- Same as above for the second slider.
- Add a control to adjust the amount of harmonic level before the mix.
- Add a Phase Shift (0-90 °) to the harmonic mix before, this does change the shape of the bass giving more effect.
- To choose a cut of the fundamental frequencies, instead of that value is from 0, never to add the key.
Indicators: Consultation, because brown bars increase by lowering the peak Maximun level (to very low values) when I understand it should happen otherwise.
Well that's all I can think of for now ...
