The Quest begins.....

Choosing the tools.

As my interest had been sparked by the open source project Guitarix I decided to use that as a framework for my experiments, this would save a lot of programming time, as the framework already existed, and ease the learning curve for DSP prigramming as it makes use of the excellent Faust DSP programming language and its FaustWorks user interface. This enables the user to very quickly develop DSP algorithms and test them as it autogenerates highly optimised DSP code and builds a variety of different plugin architectures on the fly. Check it out at http://faust.grame.fr/.

 After a very short time I was happily writing DSP code in Faust and so ready to start the experiment.

 

 

Experiments in Audio

Written by steve

This blog is a step by step account of audio DSP experiments in an effort to assess the quality of open source DSP code for the simulation of audio effects plugins.

Initially experiments have been carried out within the Guitarix project framework, a guitar amp simulation for Linux.

 I am particularly interested in the simulation of audio valve ( tube ) based amplifiers and effects as over the years I have built many amplifiers for both use as musical instrument amplifiers and hi-fi.

Whatever the reasons there is something magical about the technology that, in my opinion, cannot be matched with solid state technology.

Recent developments in digital technology, faster computers and research into simulation algorithms now make it possible to simulate such circuits.
