Developer Jonathan Higgins has released SoundThread, a free cross-platform node-based UI for the Composers Desktop Project (CDP), one of the most powerful (and previously most intimidating) free sound design toolkits around.
CDP has been a hidden weapon for experimental sound design since the 1980s, famously used by artists like Aphex Twin.
The problem is, though, that it’s always been incredibly difficult to use, requiring command-line input and a lot of patience.
SoundThread finally changes that, offering a modular, user-friendly interface that makes the power of CDP available to a much wider audience. And believe it or not, it’s completely free.
Now, I’m not someone who typically uses CDP, but here’s a quick overview of how SoundThread simplifies the whole process.
Simply put, SoundThread works like a modular audio processing playground. You load an input file, patch together various CDP processes, and send the result to an output module. That’s it.
Every thread you build creates a new processed audio file, which is ideal for resampling and exporting unique loops that you can later transfer to your DAW or wherever you’d like.
What makes SoundThread so exciting, though, is how intuitive it feels. Processes are visual blocks that you can connect with virtual cables, just like working with a modular synth.
Let’s say you want to stretch a sound, pitch it, distort it, or send it through some of the most bizarre time-domain processes ever coded. It’s just a simple drag and drop.
The interface even supports automation curves, so you can modulate any parameter over time. If you’re used to working with modern DAWs, this should feel right at home.
There’s a learning curve, of course, and installation takes a bit more effort than a standard plugin. But follow the instructions on GitHub carefully and you’ll be up and running. The results are well worth it.
CDP isn’t a basic sound design tool, though. Consider this if you want to play around with something that can completely transform sounds in creative and often super unpredictable ways.
I haven’t even installed it on my main DAW yet because I know I’ll be sucked into the vortex. I’ve got articles to write and projects to finish first.
But once I dive in, I plan to throw dozens of cinematic loops at it and harvest whatever comes out for later sound design projects.
SoundThread is still in beta, and not every CDP function is currently supported. But it’s already stable and hugely fun. If you love experimental sound design and want a tool that’s as powerful as it is unorthodox, this one’s a must-have.
SoundThread is free and available on GitHub. It works with macOS, Windows, and Linux, but you’ll need to install CDP as well. Instructions and downloads for both are included on the GitHub page.
