Neither 8 Hz nor 16 Hz

You usually should get the source data in the best quality available (=>
44 kHz or 48 kHz should be enough for a mono sound). Harddisk space is
cheap and transferring the files over a flat rate is also harmless.
This allows an optimal conversion later (and once the requirements get
bigger, eg. when all planes will use digital radios or so, we can easily
recalculate the new data)

Far more interesting is the best shape/size when the audio ends up in
the base package. There it should sound right and the size should be small.

For audio that gets transmitted over an noisy AM link 8 kHz might easily
be enough, especially when statics are added.

The audio that comes from the plane itself (IIRC that's the one we are
currently talking about) the quality is much better AFAIK. So 16 kHz
might required, if not even better.

CU,
Christian
