Creating a seamless audio loop with Timeline

Unity Engine

Hello all,
I just tried creating a seamless audio loop on an audio track in the timeline and it always creates an audible gap on the loop. This also happens when I put the same clip several times behind each other on the audio track. Using a simple AudioSource with Loop set to true produces no such gap!

Has anybody ever succeeded in creating a seamless looping audio track in timeline?

Unfortunately this is not possible with the system as designed today, please take a read of the resolution notes here as to why:

A workaround might be to use events to trigger audio sources instead - this will be more involved as you need to track state etc. It is absolutely a limitation and we are looking into ways to better support features like this in the future.

Thanks for the answer! But wouldn’t trigger an event, e.g., from a signal track, at the “end of a timeline” result in the same audible gap?
