My PC sound card is (still) the original integrated one; it’s a SigmaTel with the CXD9872RD chipset – not too bad to be an integrated sound card; plus, it has the ability to capture bit-perfect audio via the digital input – and that’s a VERY GOOD feature, when you must capture laserdisc PCM/AC3/DTS soundtracks.

It’s possible to use an external device as ADC (Analog Digital Converter); Continue reading
