In Part 1 we described the Impulse Response and how that can be used to characterize a room, which can be used to add a specific reverb to an audio track. In this post we’ll explore the process by which this is carried out, which is convolution. So what is convolution? If you have two

Creative Convolution – Part 1
Most musicians who also hang around on the other side of the mixing desk will likely have encountered convolution in its most common application for musicians and producers – reverb. A convolution reverb (such as the well known Waves IR-1 plugin) is a great way to recreate a physical space in a recording, such as

Last week I posted on twitter about an upcoming paper to be presented at SODA (Symposium on Discrete Algorithms). The new algorithm for the calculation of the Nearly Optimal Sparse Fourier Transform (Abstract). This new algorithm for certain specialized cases of the Discrete Fourier Transform, which allows processing of digital signals to create JPEG images,
