Welcome to MetaSounds, Unreal Engine’s built-in procedural audio engine! In this series, we explore the MetaSounds Editor and the hierarchy of MetaSounds: MetaSound patches, MetaSound Sources, and MetaSound Presets. We also compare procedural audio workflows to traditional, sample-based workflows, and discuss how subtractive synthesis can create highly editable and reusable MetaSounds. Then, you’ll learn how to craft interactive audio experiences with MetaSounds, such as sound effects or music influenced by player proximity; values controlled directly by Blueprints; or keyframed scenes in Sequencer.

Excellent starting point for learning Metasounds! Takes you quickly through a good set of broad examples to get you started, through a sample project, including overviews of the motivation for procedural audio. I’ve been tinkering with MS for a few months and this really helped solidify the foundation.

hello - is it possible to use the tutorial project on mac? I’m able to open the playground.uproject in UE, but none of the patches/metasounds seem to be available in the content drawer. thanks.
Hi, I’ve not tried but it should work on OS X, yes. What version of UE are you running?
hi - thanks for the reply. i’ve actually realized that it doesn’t seem to be working on PC either…same issue of the files not appearing in the project’s content drawer. i’ve got the latest versions of UE on both platforms. 
Hmm that’s strange. I think the project was developed in an earlier version but I can check it in UE5.1 on Monday morning.

Sounds good, thank you
Hey, I checked and the project was originally created in UE5.
I just opened the project in UE5.1 also to verify and I can see the MetaSounds listed under the module directories. Everything looks fine to me and works as expected. That was in Win10.
Can you see the files on your file system?
Thanks for the reply. Strange! I’m able to see files in my file system (on both PC and Mac), but not in the editor. Folders show up, but not the actual files in them. I had another friend try on his system, and he had the same issue (files visible in OS but not in editor).
Are you cloning or downloading the folder from Github?
Do the files take up space on your file system?
just downloading the folder from Github. And yep, the files do indeed take up space (647.9 MB for the whole folder)
Can you please try cloning the repo with GitHub Desktop? The files are stored with Git LFS and it could be that the “download folder” option on GitHub doesn’t work properly when using LFS.
The UE5.1 test I did the other day worked following this method on a fresh machine.

Put comments on your patches, explain what is happening there, and simplify the spaghetti.
Matt, thanks so much for this tutorial - lots of great info is contained. I’ve got a background in Max, so knew I was in the right place when I saw the PD topics. The info you’ve given is very well structured and as it’s based on UE 5, very relevant to someone (like me) who is just diving into UE now.

Hi Matt! I just feel the necessity to thank you for your insightful and inspirational Metasound tutorials because you managed to raise my interest in the audio system from superficial curiosity to something close to obsession. Please keep up converting people to DAGG geeks!
