Well, have you actually referenced the audio layer in the spectrum effect? What audio? What channels? What volume settings? you need to provide more information.
did u add audio layer
I'm having a similar problem, the same I think. I have the audio referenced in the effect.
The audio is a song file.
Not sure what channels refers to, or volume settings. The audio plays audibly when I play the project.
Also, I need some insight on this "start point" "end point" business near the top of the effect settings.
Is your audio spectrum effect applied to a solid or to the audio layer itself? What kind of format is the audio file?
