As usual, a good quality during the decoding.
8000 Hz sampling rate, this means that 4000 Hz AF are possible.
That should also be sufficient for Easypal. In this narrow DRM-mode only 
almost 3 kHz AF are needed.

I think: For the transfer of Hamradio-Data-Audio a WAV-file with 8k 
Samplig is more suitable than a lossy (psychoacoustically) MP3 with 44k 
sampling in stereo....
