Expression for movement with low frequencies audio

Postby scottkane on 09/21/2016, 6:23 am

Hi there guys.
I want to ask you scientists of Adobe AE

I need to make an audio visualiser, and I would like for example with each low frequency of the audio material, to scale an image a tiny bit each time the bass plays for example. Or something like moving the image in z space just a bit so its not static.
I need to make some audio visualizers for some music. I will owe you if you can help me!!!

Thank you very much

SoundKeys is the plugin for that purpose, you can select the frequency range you want to use for animating things.

Hello scottkane,

if you don't have Soundkeys (http://www.redgiant.com/products/trapcode-sound-keys/), you can use
the function "Convert Audio to Keyframes" in AE. But before you must build filtered audio-subfiles (Audition):

- open your audiofile in Audition (or another Audio-Programm)
- use a filter for the low band >>save as lowaudio.wav
- remove the filter and use now a filter for the high band >>save as highaudio.wav
- you can also use a filter for the midrange >>save as midaudio.wav
- load the two or three audiofiles in AE and use for each "Convert Audio to Keyframe"
- now you can use a simple Expression to use the Audiokeyframes for Scale, Position, etc.

Hi there, how do you go about doing this with Soundkeys?
I can't seem to find any parameter usable for linking that to scale for example.
Hope anyone can help! Thanks!!!
