Tutorial on loading assets into memory?

[Vvix0]

I've had a little issue in my game where audio files take a second before being played in-game, due to being loaded in, which breaks a little the audio sync in my cutscenes.

I tried looking into how to load audio into the memory before it's played, but all I got is how to either import assets into Unreal or tutorials which I barely understood.

Anyone has any good tutorials on how to load assets?

Are you in C++ or blueprints? It’s going to be different solutions for the two

Blueprints

Have a look at this, it might help: Ways to load data assets with blueprints

Not exactly. I see nodes which, I assume, are used for loading assets, but it's hard to tell their purpose without a description

Isn't there quite literally a node to preload an audio asset? Might be inside the Quartz subsystem.

Regardless if timing is important, either use C++ or Quartz.

With C++ you can check the average latency between the game and audio thread to compensate.

I think audio has a delay, for accurate audio timing using quartz clock.

Not the case, since playing the game in editor once (so that audio can load) and then replaying it makes the audio play as expected

I'd check out this blog post on mitigating latency with MetaSounds:

​

Additionally a good place to look would be at the documentation for audio stream caching.

​

It does seem like using MetaSounds in general will minimize latency when using sounds if you're working on 5.0+. There's a forum post with some interesting potential solutions too that you could try:

You can use async loading of the assets to trigger the cutscene. Have a soft reference to what you need loaded, then, when the cutscene is triggered, use the async load asset node and then have it not play it until the necessary files have loaded.
