I'm really excited that we've recently started releasing audio
recordings of Pali suttas chanted in Pali by a Sri Lankan monk. These
recordings are excellent quality, and the monk intends to record many more.

Links to the recordings are here:

The first batch is filed under November 2011, and the most recent batch
is under January 2012.

Enjoy! They're great to listen to even if you don't understand Pali, and
if you are a Pali student, hearing good pronunciation is invaluable.
