DVDs & online access for Convolution Example Transform property & other topics. Part 1 serves as an introduction to the convolution integral after discussing the discrete-time convolution based on previous videos. You can view the convolution as the inverse Laplace Transform of Y(s)=H(s)U(s) where Y(s), H(s), and U(s) are the Laplace Transform of the output response, impulse system response, and input signal, respectively.

The method of using sine wave sweeps across the audible frequency range is very much superior to the method of digital noise bursts. Watch as Dan creates the sine sweep, feeds it through his spring reverb unit, and using a method called deconvolution, creates an accurate and noise free IR. The deconvolution tool use in this segment is part of Apple Logic Pro's convolution program called perfewct space. While this is quite a nifty feature ther are other convolution tools out there, most notably Voxengo Deconvolver.

It seems this is mostly (?) used for reverb and such, but it also works with other things - like guitar cabinets. 8) So ... I downloaded a Mac Audio Unit plugin called LAConvolver, found a bunch of impulse responses, and started playing with them in Garageband. So for this recording I've got my Ash Customworks "Catherine" guitar, into my AMT Electronics California Sound distortion pedal, into my Boss CE-5 chorus, into my iMac, running Garageband, and LAConvolver. The track got cut short as Garageband threw a spak for some reason. Never mind .... I hope you like it.

Designing interesting textures with noise calls for accurate spectral control, since noise is best described in terms of spectral content. Texturing requires that noise can be easily mapped to a surface, while high-quality rendering requires anisotropic filtering. A noise function that is procedural and fast to evaluate offers several additional advantages. Unfortunately, no existing noise combines all of these properties. In this paper we introduce a noise based on sparse convolution and the Gabor kernel that enables all of these properties. Our noise offers accurate spectral control with intuitive parameters such as orientation, principal frequency and bandwidth. Our noise supports two-dimensional and solid noise, but we also introduce setup-free surface noise. This is a method for mapping noise onto a surface, complementary to solid noise, that maintains the appearance of the noise pattern along the object and does not require a texture parameterization. Our approach requires only a few bytes of storage, does not use discretely sampled data, and is nonperiodic. It supports anisotropy and anisotropic filtering. We demonstrate our noise using an interactive tool for noise design.**Properties of Continuous-Time Convolution**A short explanation that convolution is commutative, associative, and distributive.

I was going to add more to the open sides and the interior but decided against it for two reasons; one - it would require more cranking power and two, it would make it difficult to see the existing interior mechanicals. Plus, it now leaves the door open for another possible project to explore more wood mechanisms.
