In my poking around looking for a way to replace beattracker* in 26, I came across some promising looking stuff.
Here’s some “vamp” plugins, a couple of which look like they may fill the bill:
They use some recent tracking algorithms so should offer good performance. Don’t see a “phase” output, though.
Here’s a related audio analysis tool that looks like it could be good for extracting all sorts of info from audio:
I’ll give them a whirl and see how hard they are to integrate w/vvvv. I’m also trying to build the BeatTracker VST from the Sourceforge vvvv sources with VS2010 and the current VST SDK, but that’s another post…
- A beat “tracker” is not just a beat detector, but something much more involved that tries to figure out tempo, and produces outputs at that tempo. In other words a metronome that syncs itself to arbitrary input music.
