My current area of research is in sparse, event-based encodings of musical audio (https://blog.cochlea.xyz/sparse-interpretable-audio-codec-pa...). I'm very interested in decomposing audio signals into a description of the "system" (e.g., room, instrument, vocal tract, etc.) and a sparse "control signal" which describes how and when energy is injected into that system. This toy was a great way to start learning about physical modeling synthesis, which seems to be the next stop in my research journey. I was also pleasantly surprised at what's possible these days writing custom Audio Worklets!
I did notice glitching in latest Firefox on a Mac, like I'd get running a DAW with too small a buffer...While the tab was open I got similar crackles and slightly delayed audio stream playing YouTube vids in other tabs.
Working with AudioWorklets (https://developer.mozilla.org/en-US/docs/Web/API/AudioWorkle...) has been really cool, and I've been surprised at what's possible, but I _haven't_ yet figured out how to get good feedback about when the custom processor node is "falling behind" in terms of not delivering the next buffer quickly enough.
