Control Time with music rythm

[Mo Dejong]

Hi Eden

What you describe is not going to be easy to do in AA. Your best bet is to use another
piece of audio software to listen to the audio you have and create a new audio file
that contains a sound marker to indicate where the bass starts and stops. You could use
whatever audio software you want, audacity is free and would do what you want. Open the
audio you have, then create another file the exact same length but with no audio in it.
Then, get a sample like a snare drum hit, something with a clear transient. When the bass
starts, add copy and past a drum hit into the blank audio so that it lines up in time
with your audio. Then where the bass ends, put two snare hits in a row. Repeat until you
have created markers for all the start and stop points. Now export the WAV file you created
with just the snare hits and import it into AA as audio and put it in your comp. Expand
out the little triangle to the left of the track until you see the WAV display. Now, it
should be easy to see where each bass part starts and stops, so just create time remap
keyframes at those places. Set the hold property for the keyframes where the bass stops
playing so that time will not pass while the bass is not playing.

thanks should do the trick

The best way is to use Trapcode’s Sound Keys plugin.

The trick is to isolate the bass, then set the Range Falloff parameter to “None (integrate)”.

Hi dan!

I have soundkeys plugin.
Can you post me a fast example of this:
“then set the Range Falloff parameter to “None (integrate)”.”
I never done it

Thanks!

It’s really easy. In the Effects Control panel for Sound Keys:

Range 1 > Falloff > None (integrate)
