I would like to make an audio visualization where the material would change it’s color or emitter would emit something at certain moment. For audio visualization I would like to insert a keyframe at the certain moment of the beat but it’s pretty hard to find that certain frame at which the beat hits, putting it just manually requires a lot of patience and precision and often leads to missing the beat when the beat has been repeated for like 3-4 time. So I would like to just start the animation with alt+a and then simply when the beat hits or when I feel like it i would just press some button on keyboard and the keyframe would be created, just like when you are bumping with your fingers by the beat, if I want the light emitter to start emitting light somewhere around the frame 260 I would just press one button and the keyframe would be created and not like repeating the same song and frames and try to carefully listen to those beats. What if the beat is quick and it makes like 5 beats in 1 second, imagine putting that in a 60 fps video, very hard.
You’re probably looking for something like “Bake Sound to F-Curves” See if this helps.
