Amplitude Xtra - Site License 2.6

The
Amplitude Xtra 2.0 allows Macromedia Director #153; movies to respond
in real time to the amplitude data derived from sound cast members.
The xtra sends a continuous stream of amplitude values to Director while
a sound is playing. This means that, amongst other things, you can,

#149;
control sprite animations and properties by synchronizing them to sound

#149; draw sound waveforms using normal Director sprites in real time
at any resolution

#149; achieve basic lip-sync between animated characters and spoken
dialogue

#149; change inks and blend properties in time with sound and music

#149; change sprite colors based on amplitude intensity
