ChowDSP BYOD is a free, open-source plugin that lets you build your own distortion effect on macOS, Windows, iOS and Linux. 

Chowdhury DSP has released very exciting free plugins and iOS apps over the last few years. For example, the Chow Matrix is an endlessly growing delay effect with complex internal modulation and feedback that goes far beyond what other commercial plugins can do. Plus, all these creations are open-source and gives you the option to use the code in your own creation.

Today, ChowDSP is back with another big highlight. BYOD is a new free distortion plugin that is fully customizable.



BYOD is a new free cross-platform distortion effect plugin. However, it is no ordinary distortion plugin. It’s like a modular distortion plugin that allows you to craft your own distortion timbres. As in modular synthesis, there is an input and output section and various modules that can be chained together.


ChowDSP has built a huge number of versatile modules into the BYOD plugin that emulates different guitar distortion and tone-shaping circuits. Including 16 distinct drive modules (diode clipper, diode rectifier, dirty tube, waveshaper…), 11 tone modules (filter, EQs…) and 9 utilities (mixer, frequency splitter, oscilloscope…).

Lastly you get 7 other modules including a chorus, compressor, delay spring reverb… So it’s not only a distortion designer but also a multi-fx.

Another fascinating plugin from ChowDSP. I think this is the most complex that Chowdhury DSP has developed so far. Yes, it is again open-source giving other developers to learn from it, the option to incorporate it other creation or to modify it. Friends of distortion sounds can live it up freely here. It’s a distortion playground.


ChowDSP BYOD is available as a free download for macOS, Windows, iOS and Linux. It runs as a VST, VST3, AU, AUv3, AAX, LV2 plugins or in standalone. The source code is available on GitHub.
