Stephan M. Bernsee talks about developing the Prosoniq morph plug in

How did you come to develop the morph plug in?
Well, I began thinking about such an application shortly after I visited Peter Gabriel at Realworld studios where I was introducing the Neuron synthesizer. They needed a way to seamlessly morph from one sound to another for a television production they were working on. It turned out that the Neuron was capable of doing this, but it is certainly not a good idea to purchase a Mercedes when you just need an easy way to get from point A to point B. So I figured that many people might need such a tool and so we began tossing around the idea of doing a real time morphing plug in. As it turns out, the Prosoniq morph has the potential to be one of our most successful products. Continue reading…

With the increasing speed of todays desktop computer systems, a growing number of computationally intense tasks such as computing the Fourier transform of a sampled audio signal have become available to a broad base of users. Being a process traditionally implemented on dedicated DSP systems or rather powerful computers only available to a limited number of people, the Fourier transform can today be computed in real time on almost all average computer systems.

If you’re into signal processing, you will no doubt say that the headline is a very tall claim. I would second this. Of course you can’t learn all the bells and whistles of the Fourier transform in one day without practising and repeating and eventually delving into the maths. However, this online course will provide you with the basic knowledge of how the Fourier transform works, why it works and why it can be very simple to comprehend when we’re using a somewhat unconventional approach.

This tutorial gives a brief overview of the most popular algorithms used for achieving time stretching and pitch shifting in a musical context, along with their advantages and disadvantages. We provide audio examples to demonstrate common artifacts and effects associated with these processes, and provide pointers to papers and other resources on the net. Continue reading…
