I recently worked a lot with sound as a form generator for my projects. In this project i used DisplaceD plug-in for Maya.
DisplaceD is a deformer which driven by a 2D/3D Texture Nodes. You can deform every geometrys with your own painted Textures, or simply procedual textures.
Cool thing about this Plug-in is that it gives instant feedback. After desired texture map was aplied displacement is driven by the audio frequency.
