Simultaneous Music, Animation and Sound with Houdini

Info

These chapters are intended to promote and build interest in this unique area of Houdini software; and to empower the graphics artist to creatively work with some of those nebulous gray areas where an understanding of both types of communication (audio/visual) may be required. If nothing else I hope these examples will prove to be a lot of fun, and also help explain larger topics concerning procedural animation and various parts of Houdini that graphics artists might not have had the opportunity to explore. sound synthesis generated with Houdini
Houdini / Graphics / Sound / MIDI / WHAT?!* One of the exciting and unique capabilities of Houdini is the ability to natively work with audio and MIDI data. This sets it apart from all other mainstream 3D apps. Also, the procedural nature of Houdini allows you to take these areas much farther than they could normally go in other apps, even with custom code and scripting. Once the data is in Houdini, the possibilities are endless. This unique feature-set allows you, the creative mind, to be an effects artist, an electronic music composer, a character animator, a 3D spatial audio engineer, or all of the above! The Houdini artist can break free of the graphics barrier and utilize the full scope and creative potential of audio-visual media. For those who have never seen a waveform or a MIDI note before and are a little weary of diving into a completely new area of art / humanity / media / and human perception don’t be too shy. I’m continually amazed by how many similar aesthetics and concepts are shared between graphics and music/sound professionals, usually just with different names for the same overall concepts and ideas. The more I work with either area, the more similarities I find. And besides, who knows, some of our greatest musical treasures have started off completely unaware of music technology / theory / or even common sense (some still are), and great musical and sonic ideas can come from a basement, garage or even a 3D graphics artist! Advantages of Houdini in a World of existing Audio and MIDI software Houdini can read, manipulate, generate or save MIDI (synthetic notes) and Audio (sound files) data directly just like a dedicated audio and/or MIDI program. It can exchange common file formats with these programs as well. For instance you could … o Create a sound in Houdini and export it to an audio program to add an effect. o Use musical notes to animate a 3D character o Use particles to create musical notes based on which object they collide with o Place sound effects of different volumes and timbres based on where something collides in a dynamics simulation. o Create a musical score entirely in Houdini o Record a sound in 3D space with a virtual microphone o Have a character automatically react to what it “hears” in 3D space o Animate a procedural texture or compositing filter according to a particular sonic property of an audio file. o Have a character automatically produce facial expressions based on a voice recording o Things that only you can think of …
