Hi, I'm Marco from 23DSP.

Here you'll find the audio plugins I've crafted to simplify mixing and inspire creativity. I'm an indie audio developer from Italy, making plugins that bring simplicity and inspiration to music production — handcoded in my bedroom, battle-tested on dancefloors.

23DSP started as a run of small, free experiments, and the free plugins are still the most downloaded thing I have made. Season 02 is the current chapter: a rebuilt DSP framework, new plugins arriving one at a time, and the most-used older plugins kept maintained. The whole catalogue lives on the plugins page, and every purchase, licence and download is handled by Gumroad.

Beta, bugs and feedback

Most of the catalogue is in open beta, and I welcome honest feedback. If you run into a bug, tell me your operating system and your DAW — the fix goes into the next update, and reported bugs get priority. Write to hi.23dsp@gmail.com.

Supporting the work

Many 23DSP plugins are free, and they stay that way. If they have earned a place in your projects and you want to support development, you can buy me a coffee or join the 23DSP membership on Gumroad — both go straight into the time that builds the next release.
