Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Best way to integrate procedural audio

Hi all, I would like to know the best way to integrate programmatically-generated audio.

Basically I have various simple generators (such as noise, etc.) which I would make usable by any sound designer working on the project: for this reason I try to rely as much as possible on available UE4 audio features.

I wrapped those generators into SoundWaves, something quite similar to what have been done here - except that I made my SoundWaves actual assets, with a proper factory. I can create then as any other asset and assign them to SoundWave Player nodes, or some custom node (equivalent to the "USoundNodeProceduralTest" in the thread linked above) that I created and allow me to expose any parameter this generator may be fed with.

It works great for now, however I recently noticed the SoundWaveStreaming class which seems to provide some basic functionality for the same thing - is it worth using it instead? The only example I could find were SoundMod and Phya plugins which use it quite differently:

  • the first one derives from it and override the GeneratePCMData method

  • the second one create a SoundWaveStreaming instance, assign its delegate for sound generation to the proper function, and make it played by a sound component

The 2nd method seems cleaner, but in my case what would be the advantage of using SoundWaveStreaming?

Thanks for your time!

I am unsure if this would suit your requirements, but have you considered FMOD studio? They have built a plugin specifically to integrate with UE4

Actually I have, and Wwise also. But I'd really know if such things have been done relying on native UE4 framework only.

The main goal being a simpler, and wider access to procedural audio content creator in UE4.
