Creating Sound “bars” using soundkeys for layer’s Y scale
Hi everyone, I am trying to create the audio bars that you see synched to audio in players like iTunes and Windows Media, i’m sure everyone knows the sort i’m speaking of. Anyway they have a fixed width, on the x scale, but i need them to scale vertically on the y, but when i’ve tried targeting the output of Soundkeys, it scales the whole layer(bar). I want to create several different bars by targeting different sections of soundkets output. the desired animation actually looks very similar to what soundkeys renders on the layer with the effect. If i try to use the keyframe assistant>convert audio to keyframes, the same issue occurs. If anyone can help or can give me a better idea of how to produce these bars it would help. Thanks in advance!

you probably just need to separate the x and y scale components…
this expression would scale just the y component if it was linked to a layer named ‘audio amplitude’ that is created when you choose to convert audio to keyframes:
y = thisComp.layer(“Audio Amplitude”).effect(“Both Channels”)(“Slider”);

Thank you very much Kevin, but how could i make it so the changes did not so drastically affect the y scale? So the fluctuation was not so extreme? Thanks again!

you could add a multiplier to the y value… for example, if you needed the y to fluctuate at half the amount, your last line could look like this:
[value[0], y * .5)
is something like that what you are looking for?
