Hi Mikkel,
what I think you need to do is;
right click the audio> keyframe assistant, convert audio to key frames
this will make a new layer which has a slider with values based on the audio. you can get rid of left+right channels, you only need ‘both channels.’
now, go to your logos opacity, Alt click the stopwatch so you can enter an expression.
Use the pick whip (it looks like a spiral) and pick the slider.
this basically links opacity to audio.
if for instance your opacity is too low (never over 20%)
try adding something like +50; or *5; at the end of the expression.
that will get the value of the slider, and add 50 or times 5.
