[PD-ot] Is it possible to detect audio key in PD?

[Sean McColgan]

Hi list,

I am looking for a way to detect the musical key of a piece of music.
Can Pd help me?  are there any patches available which will enable me to do
this?
I am current using tonart www.*zplane*.de/ <http://www.zplane.de/>   which
is great but limiting as  I want to be able to key multiple files.

Any information or ideas kindly appreciated.

Sean
