Obscure, and yet technically superior in all ways... Bitwig == Ableton++, after Ableton management vetoed engineering's desire to do a major and much needed architectural rewrite. As I understand it, they didn't see how tearing

To me, the use case is really obvious: when you reached for SQLite but now want something with Moar Powah. Now I've reduced it to a previously answered question: what's the use case for SQLite? ;) https://www.sqlite.

Hah, it's okay :) I'm the opposite -- a large number of the things I have some above average skill at, I honestly never worked at improving, it just... happened. So I empathize with "no idea how to share" :) FWIW I al

Any advice on how to get from "fast for a normal" to "fast for a computer person" (like you)? I'm around 90wpm on a good day, but for the life of me can't break ~100. Always used to piss me off... my ex type

This sort of tech was really good at tracking drones. Neat thing about drones is they put off so much waste audio, rich with information. I know very little about drones, but, in a demo I made years ago (trying to convince someone to giv

Ah! In that case yeah, this tech could possibly help. At least, I'd love to give it a shot! (I hope you don't mind an email from me later...) It's sensitive enough to noise that I can pick up (and locate) the air vents in

I think you're talking about a different problem, though that one could also be helped with the right tool. After setting up the array, once could answer questions like "where is that darn squeak coming from!", and even cha

Funny you should link that! I have gotten as far as getting a raspberry pi zero to be a USB audio gadget, but I haven't played with the Pico yet. The raspi zero has one i2s input and one i2s output. > Pico itself can interface 29

I found that quite hard! Curious if there's anything public about your approach :) With high enough frequencies I can see reflections, but not at any distance, and the sound source has to be loud . Of course, I'm relying on lin

I'm not familiar with Acoular*, but the math involved in computing the sound coherence function over a large space is quite involved! In my implementation, there are multiple stages using a dataflow approach with lots of compile time o

Oh that's interesting! Is your thinking something like: 1. mount the array on a tripod somewhere in the frame of the camera 2. the array is covered with an assortment of fiducials, 3. software uses the known intrinsics and extrinsi

Really? Would it be "great" enough that you'd pay for such a device? If so how much? (would love to continue over email)

It can be done w/o phase locked ADCs :D it just takes... More Cleverness. I made a 16 mic array out of a bunch of trash-picked and cheap 4ch ADCs.

Interesting. I'm casually familiar with Video Amplification (the approach at SIGGRAPH a decade ago IIRC), but have never implemented it myself. A really cool result, using the changes in the phase of the basis vectors over time to in

This took me years to figure out. :) Even cooler is that you can put them in a random pattern AND have the system determine its own geometry w/o measurements.
