Analysis can be carried out by a general-purpose digital computer with a sound card selected for suitable performance and appropriate software.
The third and current version of this simulator uses a servo motor and a sound card to mimic the cardiovascular functions of the human body.
Same can be done with such software using a computer's sound card, when coupled to the telephone line.
This is to accommodate rear-center (6.1) or rear left and right (7.1) channels without the need for additional sockets on the sound card.
It performs the conversions entirely digitally, bypassing the system sound card, enabling accurate digital conversion.
The distinction is that softsynths run on a general purpose computer with a sound card, and the hardware (dedicated) synthesizers have the custom software built-in.
The success of this audio interface led to the development of a standalone sound card.
This is helpful when a sound card does not have a hardware volume control.
