IMHO none of the sound card tools fulfill the requirement of
arq (formerly known as automatic error correction now known
and CRC checking). Hence they are not used where msg integrity
is the prime consideration from origin to destination and the
msg passes thru many gateways and channels to reach its final
destination point.
