Low level interface with sound card  
News Group: embarcadero.public.delphi.multimedia 

Hello!

I would like to interface with a soundcard directly and just receive a stream of data coming from the A/D converter and send a stream of data to the D/A converter. What API / Interface is the best to start digging into? DirectSound? Does anyone have any sample code for this?

Regards, Mikael

I haven't used it but I'd say you need to look at ASIO
