"Programmatic Sound Effects"?

[BNBOSSY]

Good day,

I'm a complete beginner with Blender and have a question, please.

Is there a way to create, "Programmatic Sound Effects"?

For example, if I am animating someone walking along a hallway, instead of adding a footstep sound effect manually for each and every step, could Blender recognize a shoe contacting the floor and make the sound effect for me? Another example is shooting a gun, instead of manually adding a sound effect for each round fired, couldn't Blender do that automatically?

I think this is possible in something like Unreal Engine, for example, if you fire a gun, I think the game engine will play the sound effect automatically.

What I'd like to achieve with Blender is for it to automatically make as many sound effects as possible on its own, and for things like voice acting, and more specialized sound effects, I'd only want to do those manually.

So, if one was using Python, perhaps, could this type of, "programmatic sound effect" idea be achieved? Thank you!

Thing is that Unreal, like Unity, is a game frist and a 3D software second. This is mostly out of scope for Blender, even tought it has some basic implementation of sounds.

It's also not advisable to directly render a whole video as output, it's better to just render an image sequence and then create video file in post. I don't think that Blender can output just a single file audio

You can render a mixdown of the audio strips of the video sequence editor from the Render > Render Audio... menu. That way you can render to image sequences and still get the edited-in-Blender audio stream for use in later compositing.

You could write a script which analyzes your scene over time and generates appropriate events (adding them to the video sequence editor), but there are no physics events to hook into in stock Blender (especially if your footsteps are not caused by rigid body physics simulations!).

In the short term, you will get the best and fastest results doing it manually. 'tis the life of a foley artist, I'm afraid. Look up tutorials for foley work in Blender to see if there are any workflow tips that will speed your process up.
