  Particular/Soundkeys fireworks explode to Bass

  Posted by Till Pötzl on August 1, 2022 at 12:20 pm

  Hi there! I am looking for an automated way to let fireworks (made in particular) explode everytime there is a bass hit in the audio track. It needs to explode in random places with random colors. i fiddled with soundkeys a bit … but didn’t get the result i wanted. Could anyone help me out here? Big Thanks so far!

  Using the Keyframe assistant in the Animation menu, you should be able to convert audio to keyframes.

  Then with an expression, depending how the fireworks are set up in Particular, you could trigger them depending on the audio amplitude.

  Alternatively, you could preview the audio and hit the * key on the keypad to add a layer marker on the beat. Or if like me you have no rhythm. you can expand the waveform on the audio file and use the marker against the beat points.

  Either way, once you’re done, something like Dan Ebbert’s expression for opacity based on layer markers should help:
