Maybe the proof of concept gives someone an idea for something awesome. On OSX I would start searching for a solution with the help of the project "Soundflower", but I'm not sure how easy that will be. On Linux capturing the audio should be very easy for example by directing arecord 's standard output to the UE4 program's standard input and going forward from there, but haven't gotten around to trying that yet.

Finally on each game tick we fetch a list of new frequencies, and if found, add those to the mesh, and move the camera forward to keep up.įeel free to ask me on Twitter or in the comments if something is unclear! Making it work on platforms other than Windows Now that chunks of audio are popping into a queue from which we can dequeue them in the UE4 main thread, we can calculate the sound spectrums for each audio chunk we receive. An audio sink for the audio capturer receives chunks of audio frames from the capturer, and the audio listener itself is ran in it's own thread within the visualizer process. On Windows, we're in luck because we've already done the audio capture part, now we just direct it towards UE4 instead of a file. A very brief and dense overview on how it works

Some of the code for figuring out frequencies from audio chunks is from eXi's sound visualization plugin, especially the original CalculateFrequencySpectrum function that can be found here, and his use of the library KissFFT.īecause I'm proud that I was able to figure out the frequency calculating part myself as well, I want to add that I have my own implementation for it (with the help of the library "ffft"), but for this project I overwrote that with eXi's solution to rule out bugs in that area. Thanks to other open source projectsįor the mesh generation part I got a lot of help from SiggiG's procedural UE4 project/tutorial which lives here: Due to a yet unknown reason the standalone version basically doesn't work at all. Education Ecosystem referral program offers you a great opportunity to earn additional LEDU by inviting Friends Invite a Friend. The program also does not release all the memory that it should. Unreal Engine users who want to get into procedural mesh generation. Spotify, Youtube, or any other audio source on Windows works straight away as well.Ī word of warning though, it's only a proof of concept, so it is not stable! In-editor it generally works well, but sometimes crashes. Here are two example videos of it running live where at the beginning I just press play in Foobar on Windows, and the visualization begins.
