I have been tidying up here, and have split the soundclips into Concert Pipes, Flat Pipes and the A chanter, Eb chanter and Northumbrian clips

Here is an interesting recording of the same chanter design, same cap, same reed, different timbers. Ebony Palosanto Mountain Mahogany All Three but in which order?
The differences are subtle, but are there. Same position from the Rode NT1 (I may try again with the K2 if I get chance) and same settings.
