Audio Visualization in Blender | Convert Any Sound File or Audio Into F-Curve | Wave Form Animation

In this tutorial, we have discussed how to convert an audio file into f-curve, and how to create audio visualization, in Blender. This is the first part of the tutorial in which the basic settings are discussed, with a simple frequency-level sound-bar construction. In the next part, we will discuss how to synchronize the motions of any object with an audio or sound input. Please watch the video for the complete tutorial.

Note 👉 For Blender 3.6 onward, there are some changes in the menu options. Now the Bake Sound to F-curve option comes under the Channel menu instead of the Key menu (same for Bake Curve and Unbake Curve). The functionality remains the same, only the menu location has changed.

[@jozsefbaka825]

Thanks for the tutorial! A quick tip: don't delete the F-curve before applying the array modifier. Instead add another F-curve modifier, called Limits. Now you can apply array and separate the elements. Now all you have to do is change the Maximum Y value on the Limits modifier on each object. This is much faster than importing the audio file over and over again, especially with 50+ bars. Also it's easier to change it later to a different value.

[@5MinutesBlender]

Thanks for the info! Very useful tip 👍

[@SUDO-gm2if]

I also used minimum y of the limits it acts like the lowest frequency. Also the envelope to position the entire thing

[@TronHutson]

Good tutorial! Didn't know it was possible to make a sound bar audio visualization that easy with Blender

[@5MinutesBlender]

Glad it helped. Cheers!!

[@hope3d502]

Nice tutorial. I've applied this method using bars too but with no frequency range, only baking the audio curve with 1 frame of distance between the each bar individually (First bar, frame 1 and bake. Second bar, frame 2 and bake...). For 20 bars it looked pretty awesome, just like any old audio equipment.

[@5MinutesBlender]

That's great! Nice work!

[@WolfSeril107]

Thank you for the info about the frequency min/max! That is exactly what I was looking for. Other tutorials only use a single curve and their animations are very flat because of it. I was worried I would have to make separate audio files before importing to blender.

[@5MinutesBlender]

Great to hear that it helped you! Cheers!

[@SMthegamer2]

Honestly pretty annoyed I only just found out about the frequency option, because I did make separate audio files... over 30 of them for each frequency band I wanted.

hey I was wondering if you know why the curve disappears when I unbake it? usually I unbake it and use alt o to smooth it out but when I unbake the curve it just gets completely flat.. I've never had this issue

[@5MinutesBlender]

For me, the curve does not disappear after unbake. I am getting key points as expected and the curve is preserved. So I am sorry but no clue about your issue because I am not able to reproduce that at my end.

[@MM-od9gr]

hey, i once used this and it worked fine on shape keys but also combined with a wave modifier. (f curve only on the shape keys) for linking crying sounds to objects/creatures for their movement. and now its not working anymore it seems like the sound is not the soundwave that i bake in the f curve and it seems off. like its lagging do you maybe know why? i also rendered it out bc i thought its just blender being slow but it was still the same.. like the movement didnt match the sound

[@5MinutesBlender]

Blender would map the sound wave starting from the current frame. So ensure that you are at the current frame number in the viewport when you invoke that bake sound function. You can rectify it later as well by moving the keys together (forward or backward as needed). But if the lagging is not uniform, sometimes slower and sometimes faster, then it might be some other issues.

[@MM-od9gr]

@@5MinutesBlender hey i was having a wrong samplerate in the audio i figured but thank u !

[@5MinutesBlender]

@@MM-od9gr Glad to know that you have resolved the issues!

[@Altitude962]

Hey sir please help me i am in great trouble,my character's sound stucks in final render and also sometimes lipsying doesn't work in final render plese

[@5MinutesBlender]

I have no idea how you have added the sound or how you have implemented the lip sync, so it is difficult for me to suggest something with a cursory description of the problems 🙁

[@atakandurusoy]

Hi, great tutorial, thank you.
I am doing the same thing using speech mp3 files. So I have 5-6 speech mp3 files. Is there a way to connect the same bars to 5-6 different mp3 files though the timeline?
Thank you in advance 🙏

[@5MinutesBlender]

Do you mean to say, from frame# 1 to 500 they should be mapped to the first mp3, then from frame# 501 to 1000 second mp3 etc.?

[@atakandurusoy]

Yes exactly 🙏🏼

[@5MinutesBlender]

One way to do that is to create 5 objects and map the 5 sound files to them. Now for your original object, add 5 CHILD OF constraints with these 5 objects as parents. So the scaling of your original object will follow the height of its parents. You have to control the influence factor of these constraints such that only one constraint is active at a time. You can keyframe the influence factors so that the 1st object is the parent from frame# 1 to say 500, the 2nd object is the parent from frame# 501 to 1000 etc. The other option is to externally join these mp3 files into one single file and use that as the sound source. For CHLD OF constraints, you can check our tutorial 👉 czcams.com/video/Bagw9W0jXhA/video.html

[@atakandurusoy]

Thank you so much 🙏🏼

[@RadioactiveHax]

Hi I was just curious but how do we amplify the frequency of the F curves? My bass is working fine but my hats (upper 10000Hz) is not showing much.
I love this vid. Thanks so much you earn a sub.

[@5MinutesBlender]

Glad you liked this tutorial. You can scale up the F-curve by using the S key (very similar to how we scale up objects in the viewport). First unbake the curve in order to get the keyframes. Select the required keyframes. You need to increase their height, so press S, then press Y (to lock the scaling only in the Y axis), then either move your mouse or type some number and hit enter. The F-curve will increase in height, so the movements will be now more visible.

[@archerslogic]

@@5MinutesBlender Thanks for the tuto, the envelope modifier in graph editor works too by tweaking control points

[@5MinutesBlender]

@@archerslogic Yep, thanks for sharing the tip 👍

[@leonardoz.4591]

Why don't work with me? :(

[@5MinutesBlender]

Hi, can you please tell me which step is failing or where exactly are you stuck? You can give the timestamp as well, it will help me to understand the issue better.

[@leonardoz.4591]

@@5MinutesBlender the bars move very little, almost imperceptibly

[@5MinutesBlender]

@@leonardoz.4591 Please check the frequency range that you have used. Each audio file has its own characteristics, you need to derive the frequency range based on that. It needs a little experiment before you can discover the best resuls. Also the audio file should have good variations or ups & downs. For example, a flat soft background music may not have much variations. If nothing works, you can send your blend file to us, along with the audio file. We will be more than glad to help you. Thanks!

Thank you for this tutorial. It helped a lot for a music visualizer I made in Blender. czcams.com/video/XYprCnmFINM/video.html
