Time scrubbing example project

Audio to position Expressions example:

var x = transform.position[0];
var y = transform.position[1];
var d = thisComp.layer("Audio Amplitude").effect("Both Channels")("Slider");
[x, y-(d * 50)];

...adding linear scale:

var x = transform.position[0];
var y = transform.position[1];
var d = thisComp.layer("Audio Amplitude").effect("Both Channels")("Slider");
d = linear(d, 2, 13, 0, 200);
[x, y-d]

...using audio to drive Time Remap

var d = thisComp.layer("Audio Amplitude").effect("Both Channels")("Slider");
d = linear(d, 2, 13, 0, 100);
d;

Audio files: AIFF or WAV uncompressed --only use MP3 for distribution.
