In my work as an audio plugin developer, I spend a decent amount of time doing what some would call “virtual analog modelling,” or “physical modelling”. …

Wave Digital Filters (WDFs) is a circuit modelling paradigm that has become quite popular in recent years. While using WDFs to emulate circuits made up entirely of series and parallel combinations of elements is fairly straightforward, using WDFs for more complicated circuit topologies is a bit more difficult. The idea…

If you’re using neural networks to process signals in the time domain, you’ve probably run into the following problem: I trained my neural network on data at one sample rate, but now I want to use that network to process data at a different sample rate. The Problem For some types of…

Over the past couple years, I’ve dedicated a significant amount of research time to the implementation of neural networks for real-time audio applications, specifically real-time audio effects that can be used on desktop computers, mobile devices, and embedded devices. …

A few weeks ago, I was fortunate to reconnect with a former co-worker whom I had not seen for several years. Let’s call him Chris. Since meeting with him again, I keep thinking back to one particular moment from our time working together. I was working to implement a new…

For the past few years, I’ve been working semi-regularly on an open-source tape emulation audio plugin called CHOWTapeModel. …

As a programmer who develops open source audio plugins, I suppose it was only a matter of time… Let’s say that you’re an audio plugin developer, and one day you decide that you would like your plugins to support Linux. …

A couple months ago, I was doing some research into emulating bucket-brigade devices for creating analog-style delay-lines, when I ran into a rather interesting paper, written by Martin Holters and Julian Parker. Although bucket-brigade devices (BBDs) are made up of analog circuits, in concept they behave like a fixed-length digital…

Over the past few years, the world of audio effects has seen an increasing interest in the use of neural networks to process audio in real-time. …
