art3mis Posted April 21, 2017 Share Posted April 21, 2017 Greatly inspired by the piece 'Oscillate' on vimeo. Can anyone point me to tutorials for audio driven animation in Houdini? Quote Link to comment Share on other sites More sharing options...
edward Posted April 22, 2017 Share Posted April 22, 2017 The traditional resource for this is the e-book "Simultaneous Music, Animation, and Sound with Houdini" by Andrew Lowell. However, his site is now down so I don't know if it's still available for purchase. However, I think Peter Quint's tutorials are still available: https://www.sidefx.com/tutorials/chops-and-music-driven-animation-i/ https://www.sidefx.com/tutorials/chops-and-music-driven-animation-ii/ https://www.sidefx.com/tutorials/chops-and-music-driven-animation-iii/ Quote Link to comment Share on other sites More sharing options...
art3mis Posted April 22, 2017 Author Share Posted April 22, 2017 Thanks! Yes had heard of Andrew Lowell's book but never got around to ordering it:(. Will try to contact the author. Quote Link to comment Share on other sites More sharing options...
Guest tar Posted April 22, 2017 Share Posted April 22, 2017 It would be a great thing if Lowell open sourced the pdf as a tutorial Quote Link to comment Share on other sites More sharing options...
Atom Posted April 23, 2017 Share Posted April 23, 2017 I put together a short video on how to use audio to drive animation. 1 Quote Link to comment Share on other sites More sharing options...

mestela Posted April 24, 2017 Share Posted April 24, 2017 (edited) I've found in the past that stuff that looks like audio driven anim often isn't; its very hard to remove that bad winamp/screensaver quality to things, frequency analysis and whatnot often don't translate to interesting visuals. Not to say its not worth exploring, but that very nice vimeo piece looks mostly hand keyed to me. The other amazing example of this from many years ago is 'gatz graf' by Alex Rutterford, that was definitely hand keyed. Anyway, here's a quick attempt at controllable sine waves, shader, particles kindasorta like that first video, might give you some ideas. waveforms2.hipnc Edited April 24, 2017 by mestela better example 1 Quote Link to comment Share on other sites More sharing options...

Hand-keyed is probably still "audio driven animation" albeit with a lot of manual work. The other aspect is that there's nothing wrong with manual tweaking on top of a procedural solution as well.

rich_lord Posted April 24, 2017 Share Posted April 24, 2017 @mestela Always been amazed that someone could be bothered to hand key that video. Quote Link to comment Share on other sites More sharing options...
mjparent Posted September 21, 2020 Share Posted September 21, 2020 (edited) I want to reproduce in a small version the oscillation as in oscillate. I am stock. I've look at different tutorials, and read these post but my comprehension has hit a temporary limit. So I would like to make just a wave getting out of a turntable needle as in the picture included. I also wanted the particles to express the pulsation... too many things and I lost the understanding of all of it. Would there be someone to give me some support on this please ? this is for a project at school, my last year and the level is going too fast for me, so I am learning to learn and asking is one of the thing I am learning. Thank you in advance. Hope I can find some help.

mjparent Posted September 21, 2020 Share Posted September 21, 2020 (edited) Well you had that gramophone at hand ! yes with following the music... omg this is so complicated. but just trying to express my problem, gives me some clarity. ModeBaroque_FlipBook_Short_000.mov At least there is a conversation about it, and it is fascinating.

mjparent Posted September 21, 2020 Share Posted September 21, 2020 If someone finds it fun to look at and help me solve my problems that would be great. I'll share the two files that I set up. One is with the lines oscillating and the other is more the points that are moving in Y. But what I want to accomplish is that I could get the point/particle be pulsing out on the oscillating lines. I am very new to Houdini. So there is no vex. I'm just at the beginning. Just using the CHOPs network is a great deal of challenge, but I guess I was compelled. I'd love to know more and do more audio driven animation, I see so many beautiful realisations.

mjparent Posted September 22, 2020 Share Posted September 22, 2020 (edited) Yes I know, but the situation now is that everything is done at home, we didn't add no assistant yet, but I ask this week and there will be someone to help. Thank you very much for this support. I'll look at those links and I will share my work if it is possible. Here is what I have been able to do. I want to share as a very little give back for all the support I have from this group. It is not perfect. I will be using what I have learn in this project in my next one. I really like that the music animate the form, whatever form it is. Again, thank you for your help.
