Master Animation in After Effects with our Motion Beast course:

Hi, guys! Today we want to share with you a versatile way to create a Sound Wave with Shape Layers. And the good news is that you can loop this wave as well using the following expression
freq = 6; //frequency
amp = 500; //amplitude
loopTime = 3; //loop duration in sec
t = time % loopTime;
wiggle1 = wiggle(freq, amp, 1, 0.5, t);
wiggle2 = wiggle(freq, amp, 1, 0.5, t - loopTime);
linear(t, 0, loopTime, wiggle1, wiggle2)

Or you could use the Audio Spectrum or Audio Waveform effect and have the sound wave respond to an audio layer

Thanks a lot, that was the first tut I watched and felt like I didn't learn anything, but your comment gave me the answer I needed, thanks !

It's sometimes very hard to get a good result from the Audio Waveform connected to the MP3 you import. I guess a good tutorial is needed for that as syncing to the sound is crucial

Try with audio spectrum

[@kucingvirtual9791]

Alhamdulillah, nice tutorial and tips

[@iandykes757]

can you save the image as a file keeping the pattern and colour

[@Minitomate]

LOL, awesome, but what if I want to react with the music?

[@Tripplejdog]

Mini tomate you can add a time remapping property and set it to sync with sound from a clip!

[@visualsbywlroo]

Create a solid - then add audio spectrum and have a play around - you will need to make sure the layer is reacting to the music by changing which layer it reacts to within the effect itself.
