Until now, Diretta has been connected via ALSA or ASIO audio interfaces
Since Diretta uses a network protocol, this connection results in some loss
Connecting directly to the player reduces this loss.
Reducing the number of buffer copies results in a more direct effect
Developers can use the Diretta Host SDK to develop players
