Stop using private variables in virtual functions please!

Thank you for your responses, they are really helping me as I try to learn UE4’s audio system! I will play around with the code you posted to try and get what I want up and running.

I don’t think you’re understanding what’s going on here… So the cap is there because the system is actually not allocating a new buffer each callback so 8k sample max is there because there’s a max buffer size already allocated in the lower level.

It’s also intended for real-time (procedural) generation of audio data. If you want to generate a precise 1 second of audio data only all at once, feel free to do that! But you’ll have to feed it the procedural audio callback in small chunks due to the way the whole system is designed. It’s not designed to allow you to feed one big chunk of data all at once and call it day.

You’ll need to track the current sample read position against the total number of samples generated and copy only the amount of data the callback wants.

I don’t understand what you’re trying to do. You don’t call the callback, the playing sound wave does.

So, I start my sample almost exactly the same way you do from my AudioComponent. The problem I was having was that my sound only played once, for the 8k samples, and then quit. I have to keep calling “PlaySoundAtLocation” over and over again in order to get the callback to keep going.

Let me know what cool stuff you come up with! The possibilities are endless…

For sure! I’m super excited.

Edit: One more question, may I ask the type of variable SineOsc is? FSineOsc from here: “UnrealAudioTestGenerators.h” ?
