You can do this in either the Animation Sequence Editor, or in Sequencer (by first baking the animation to the Face Control Board), then accessing the animation curves using the graph editor (last button on the right in the Sequencer Tool Bar that looks like … well … a graph).
There’s a filter field above the tracks list that lets you filter by curve name. Would recommend only having a few curves visible/listed before going into the graph/curve editor as things slow down if you try to open/view all the keys on all the curves at once.
BTW, for noise/jitter, both of these tools/windows have a button for filtering. FFT Butterworth low pass filter is really useful for smoothing out jitter (high frequency noise) while allowing the overall motion curve to pass through smoothly.
Hope this helps.
