controlling the volume of an audio source that is not controlled by timeline.

i want to control the volume of an audio source that is not inside my timeline.

i do not want the audioclip to stop and start with the Timeline, i only want to control its volume.

do i need to create a custom track type to do this? ( i need to control the volume property with a curve editor) or is there already a way to achieve this?

You can use an animation track and animate the audiosource volume.

of course…totally overthought that one.
