Audio Codec Test Files

The following audio files are made available to evaluate audio codecs at low bit rates. This is of interest to folks wanting to get audio programmes out of NZ to the Pacific Islands, Asia and rural NZ (is that a new definition of  "out of NZ" ? - oops)

Feedback is appreciated to info@r2.co.nz
