Motion Sounds
Motion Sounds adds sound effects to the Video Sequence Editor based on bone motion events. It detects when armature bones cross a specified Z threshold during animation and inserts sound clips at those frames in the Video Sequence Editor. Features include speed-based volume mapping (faster motion = louder sounds), random or single sound selection from a folder, and volume randomization.
See it in action in the demo video.

Add default sounds
OMG yes, thank you for doing this!! Something like that was absolutely missing.
Do you think adding sound strengthening depending on the distance to the camera would be possible? Also crazy would be to get "sound collision" where objects could block the sound like cg matter did here https://youtu.be/hgLwpTvW21E This could ofc be a paid addon also, in any way, thanks for using your time for the community <3
Hey, this addon is incredible!!! I was looking for an addon like this for about two monthes, but here i propose some improvements:
➡️It only supports Armatures: It would be interesting 👍👍 to use it with normal objets, that collision without bones.
➡️It only supports some types of movement detections: It would be incredible 🤩🤩 if it detects different types of movemets: Roll (ball), Impact, Slice, etc.
➡️It only suppports random or sigle sounds: It would be perfect ⭐⭐ that you could use different types of custom sounds for the different types of movements detected.
I hope you can improve this addon, to be perfect. Thank you very much. (Excuse my English, I'm form Spain).
wonderful add-on. Thanks so much!
Have you thought about an option to automatically place a speaker object in 3d space at the trigger location? This way you can get the audio to move around in stereo, or even get a free Doppler effect depending on camera movement.
I've always wanted to incorporate audio a lot more in my workflow within blender and I can see myself finding this add-on very useful!
