Beat Reactor

The BCC Beat Reactor is a filter that can be used within Adobe After
Effects to generate keyframes based on an audio track within the composition.
These keyframes can be used to affect other parameters within the composition
by using very simple AE expressions to link the generated keyframes to other
parameters or by copying and pasting the generated keyframes to other
parameters.

Beat Reactor displays a spectrum graph including vertical bands representing
the audio levels within various frequency ranges. This graph can be used to
help target particular elements within the audio track for use in generating
keyframes.
