Audio Factory encodes at the audio's native 48 kHz; this is what the 
stations operate at internally. 44.1 kHz was a legacy thing and to be 
honest was unnecessary; after stations went all-digital at 48 kHz it 
effectively gave us three resampling steps (48 -> 44.1 -> 48).

Now we have zero additional resampling steps (save for anything like 
commercial music, which will have been resampled once from 44.1 kHz 
source to 48 kHz).

Don't get confused with the HLS bit rates (of which 48 kbps - 48 
Kilobits per second - is one). :-)
