Question [4.4+]Adjust the Headphone/Speaker button level

Hi guys ,

I just flashed this rom: Paranoid_SaberDroid_4.1-BETA2 and i have a bit uncomfortable with volume buttons.
It's take a lot of times pressing to adjust speaker volume from 0 to full (30 times pressing)
I think we need to 15 - 20 times pressing are enough.
Please let me know how to change this parameter to decrease times volume button pressing.
