I have followed some tutorials how to make a vu meter, to a sound file. That seems to work for me! I have added the function to have more bars than one, with a high and low pass filter. This is how i do it.
Sound bar is ready
Add sound file
Convert audio to keyframes
Then i add the high and low pass filter, on the different audio amplitude, that seems to work. The bars are moving different. That means, that it will generate the keyframes after, is that correct ?(1)?
Now my big problem is, i would to add different music files, but having 20 bars will take a lot of time, making new amplitude keyframes every time, is there a way for this, now it looks like it generates keyframes afterwards(possible to add sound filters after generation og audio keyframe)?(2)?
Hope someone can confirm 1, and answer 2!
Have just realised that it was the same, when adding filter after converting to audio keyframes.
So now i need
1 - Generating new keyframes, after adding filter
2 - I need to change audio file
I think you want to do the high and low-pass filters BEFORE you convert audio to keyframes. That way, it will create keyframes in the frequency range you want.
