Double integration

[Magnetic]

Hello guys.

I need to have a double integrator circuit for my last design about Particle detectors.
The integrator should covers the audio spectrum, so it should work and covers frequencies up to 15kHz.

Any idea about a good integrator circuit?

Somebody suggest me to use tone control circuits as an integrator but I have no idea how those tone control circuits do so, And I have no idea using just one to get doubled integration or just one tone controller is able to so?

Thanks for any help.

What particle detector are you using?
