[FCP] Audio Keyframing - Linear?

How do I get the audio keyframing to be linear instead of this curve?

Audio is logarithmic, so in short, you can't.
I assume you are coming from Avid or Premiere, where the audio fade is linear. It only looks linear in those programs. Audio by nature is logarithmic, so FCP's fade works the same as all the others, it just looks different.
