Make OS X volume change system volume in quarter increments by default?

[mgpg89]

Recently got a new Bluetooth-enabled speaker system, which can get pretty loud.
While this can be highly entertaining, it also has its downsides.
The standard 16-step volume increments are too big a difference at low volumes.

I now find myself adjusting system volume in 1/4 increments using by using the Alt+Shift+Volume shortkey.

However, I would like a solution where I can have OS X change system volume in quarter increments by default. (So, press 'volume up' would result in +0.25 instead of +1)

Is this possible?

Thanks in advance

I would assume there is a way to do it, but it would require some tweaking.

I looked around and it seems like that shortcut you mentioned is the only way.

You can also use KeyRemap4MacBook to remap F11 and F12 to ⌥⇧F11 and ⌥⇧F12:

<autogen>__KeyToKey__ KeyCode::VK_CONSUMERKEY_VOLUME_DOWN, ModifierFlag::NONE, KeyCode::VK_CONSUMERKEY_VOLUME_DOWN, ModifierFlag::OPTION_L | ModifierFlag::SHIFT_L</autogen>
<autogen>__KeyToKey__ KeyCode::VK_CONSUMERKEY_VOLUME_UP, ModifierFlag::NONE, KeyCode::VK_CONSUMERKEY_VOLUME_UP, ModifierFlag::OPTION_L | ModifierFlag::SHIFT_L</autogen>[CODE.
