I've been deep into x-platform development lately for an experiment I'm working on. It involves multiple devices, and will incorporate EEG and potentially a bunch of other things. A nice result of this is that I've managed to get liblsl running on Bela.

If you're not familiar with LSL, it's a timestamped, drift-correcting network data streaming library that can send all kinds of data, including real-time audio, and you can then process the data in real-time and forward it on to an outlet stream, or do whatever you like with it. It's used frequently with neuroimaging data, but also for other equipment and of course it's very relevant for audio too.

Source code and instructions for using the library or building it yourself are available here: https://github.com/zeyus/Bela-liblsl

Here's a demo of it in action 🙂

Nice. Year ago I was helping a friend at university with something like that, it was EMG acquisition (not sure it was LSL?) and they required accurate timestamping and alignment of HID events and EMG data and I was like ... "well if it was me, I'd try to do this on Bela". Now we know how it should have been!
