I'd like to learn a bit more about chromagrams. They seem to be popular for analysing the harmonic structure of music audio. I wanted to try out a few ideas of my own, but before getting too deeply into it I was hoping to have a play with some existing implementations.
I'm experimenting with the current version of Sonic Visualiser
. This looks like a pretty cool appliction, and I love the fact that someone has finally
come up with a plugin API for audio feature extraction. Thanks to the team for your great work!
The Vamp Plugins Page
mentions chromagrams under the "Queen Mary plugin set", but it looks like these are currently unavailable. I tried an older version of these plugins from here
but these seem to make the host hang on startup.
- Does anyone know if/when the Queen Mary plugins will be available again?
- Is there an older version of Sonic Visualiser that works with the earlier plugins?
- Are there any other applications or plugins around that do chromagram visualisation
