 Lowest latency. Requires special audio device to support ASIO, at specific format (e.g., https://iidx.org/infinitas_asio for IIDX, which needs Int24LSB)
 
+So far, only IIDX TDJ and SDVX VM support ASIO. They both require a specific sound card, Asus Xonar AE. You can use options in Spice (-iidxasio and -sp2x-sdvxasio) to override this to use your own ASIO sound card. IIDX works reliably with some cards. No known cards for SDVX.
 
+## Spice audio hooks
+
+Spice has an audio hook that can accept **WASAPI exclusive mode** as input, and output as ASIO or waveOut. waveOut is not recommended.
