noise.sh VS Pure Data

I actually made something slightly like what you're looking for: https://noise.sh It's certainly not as powerful nor polished as Bespoke but might be worth a look. - Source: Hacker News / over 2 years ago

Shameless plug for my own audio programming experiment: https://noise.sh It's not as powerful as something like PureData but it does give you a good introduction to DSP and audio synthesis. - Source: Hacker News / almost 3 years ago

I love this! The in-browser synthesis here was a big inspiration for my side-project: https://noise.sh (spreadsheet for sound design). - Source: Hacker News / about 3 years ago

For node based workflows, check out Max or Pure Data. https://cycling74.com/products/max https://puredata.info/. - Source: Hacker News / 3 months ago

Tools like Ossia Score, Chataigne and PureData (pd) can also help a ton in building interactive art and triggering other A/V software. Source: 12 months ago

WebPd is a highly modular compiler for audio programming language Pure Data allowing to run .pd patches on web pages. It converts the audio graph and processing objects from a patch into plain human-readable JavaScript or WebAssembly which can then be integrated directly into any web application.

You might also be interested in the very different Pure Data (http://puredata.info/) environment, which is also free and open-source. It uses a visual programming approach, which many people like but if you are already a programmer it might seem inconvenient in comparison. Source: about 1 year ago

Personally I got started with pure data, which is open source and a good place to learn DSP basics. I think there are even a few wrapper libraries for building things into apps (libpd, mobmuplat, to name a few). Source: about 1 year ago
