Can anyone recommend a good way of changing keyframes in Audio Amplitude?

[DanielHaskett] “ive also been trying to use soundkeys which admittedly has more variation to it, but still creates so many keyframes…is it just about going through and deleting, changing where necessary? “

The key in SoundKeys is to change the properties that control what audio is analyzed to generate the results, then change the way the results are given. For example you could limit the analysis to a certain range of frequencies and amplitudes, then generate values between 0 and 90 (or any arbitrary number) based on the amplitudes the analysis finds. If you use a lower and upper threshold, then anything at or below the lower threshold will return 0 and anything at or above the upper will return 90.

Additionally, you can use a smooth(); expression on the keyframed property to smooth out the jaggies if necessary. This could be very effective if you set SoundKeys to only return either 0 (closed) or 1 (open), then for your angle property multiply the result of the SoundKeys effect by your maximum angle and smooth() the result.

You can also use Window > The smoother to smooth out keyframes.

Select the keyframes and then apply the smoothing. It will delete man if the keyframes.

Soundkeys is a much better option overall when working with audio.

Hey Darby,

Thanks, that sounds like a great idea, im definetly gonna look into that.

I was just wondering if you could help with a couple of other related things, basically this is a very rough example of the animation – https://www.danhaskett.co.uk/ani%20clips/bottles.mov

basically i want water to splurt out of their mouth and also for the water line at the top of the bottom to wave around as it moves.

i was thinking i could link both of these 2 the soundkey keyframes. so ill make an animation of some water splashing out, and then maybe link its opacity to the keyframes…altho maybe not opacity, would need it to tell the animation to start whenever the mouth opens…so maybe like link it to time remapping? hmm….do you have any ideas?

with the wavey link at the top of the bottle i was thinking of using a mask, but any suggests as to how best to create a kind of wavey moving effect on the line? i guess i could link a slider control to the audio keyframes, so that whenever the mouth opens, the line is more wavey….

phew…well if u have any additional ideas itd be much appreciated!

thanks
