Houdini - Basic audio generation in CHOPs

[@antoniocottone2961]

Hi Fabricio! I really love your research works. Thank you for sharing! I had a question: Is there a way to transpose an animated spline directly to an audio waveform? Thanks!

Hi, thanks! You mean like a simple waveform visualizer? yes it is totally possible. This visualizer would be just a slice running along the full waveform as the audio is played. you can create a flat line in sop and use its point indices to query chanel samples from chops. There is a small conversion you need to do: time to chop samples (considering your channel sample rate), so your sop line middle point stays exactly the current time sample being played and first/last points corresponds to the waveform slice you want to display. But it is super easy overall, I have a hip example somewhere in my pc. Will try and make a tutorial for it soon!

Thanks so much for making this video, there are almost no other ones available on the topic

Would love to see the video you mentioned with driving audio based on physics collisions and such

[@Aguiraz]

exactly, that would be awesome. I am struggling to find a way to generate impact sound based on vellum grain collisions

Looking forward to watch more content like this ;) muito brigado!

Great, thanks Fabricio!

Really great, man. Thanks
